Breeding sheep to eliminate dags and worms. 1.

By Dr Clive Dalton

PART 1


Introduction
  • Farmers used genetics to improve fertility in their commercial sheep flocks in the 1970s - 1980s, and this greatly improved income.
  • But with recent inflation and currency fluctuations, they realise that more lambs are not all profit.
  • Rising costs, especially for animal health are now a major issue, but veterinary science has not come up with ways to reduce these; so-called progress seems to be to use more!

Dagging and drenching


  • These are the two main killers in terms of cost and physical effort, as sheep farmers’ average age is now creeping up towards 60, with fewer young people entering the industry, or who want to spend their time wrestling with today’s 80kg sheep.
  • Many sheep farmers have back, hip and knee problems from hauling sheep around, and the veterinary profession are only offering more drug and chemical therapy as future solutions, which will not reduce costs.
  • This approach is not sustainable – neither economically nor for the environment.
  • So the obvious conclusion is that we have to stop, (or at least greatly reduce), dagging and drenching sheep.
  • If you don’t agree, and are happy to get the handpiece out to clean up sheep like the one below, then don’t read further.
What a prospect to have to clean up this sheep's rear end!

Major mind change needed

Sheep are never keen to cooperate
  • Dagging (to prevent blowfly) and drenching (to kill worms) have always been accepted as part of sheep husbandry.
  • So has crutching, most of which is done to prevent dags forming.
  • You never see these chores featured in a shepherd’s job description: they are taken for granted.
  • If the boss had no jobs planned, then he/she could always find some dagging or drenching to do to keep staff active and give the dogs a run!


This advert in a 1970 New Zealand Farmer was certainly convincing.
Back then, nobody thought about long-term implications of the
new wonder chemicals!


Breeding is the solution

  • Breeding is the way to get rid of the endless chore of dagging and drenching, which inevitably is followed by more dagging and drenching.
  • The chemicals used in drenches cannot be sustainable, and consumers will start to demand ‘drug-free’ products for their health and welfare.
  • Genetic gains are cost effective and they are not lost.
  • But breeding as a solution has been hard to get through to farmers, as since the modern anthelmintics came on the market in the 1960s, farmers have been bombarded by myths and untruths.

Myths & untruths

A typical range of anthelmintic chemotherapy products on the market.
Sold in bright coloured packs with regular promotional specials.

  • Breeding is too slow. Breeding for Facial Eczema (FE) resistance for example took nearly 30 years. True but there are reasons – see below.
  • Drench is faster, and with the new products on the market that kill everything, the problem of drench resistance has been solved. Not true.
  • Vets who sell drench hardly ever mention genetics to their clients. If they do, it’s always as a last resort. Drench sales are a significant part of vets' income and the more they sell the bigger markup they can negotiate from the manufacturer supplying them.
  • Genetics doesn’t seem to figure strongly in their university training, and in any case they don’t sell rams from their clinics!
  • If you start a breeding programme, you’ll be buried in paper and will need a computer. Not true.

Breeding for FE resistance – why it took so long?


Hogget with FE which is clearly suffering pain and distress.
It also cannot see as its eye lids are swollen up.


There were plenty of reasons:

  • The sporidesmin toxin harvested from the fungus was so horrendously expensive that stud breeders could only afford to dose a few of their rams.
  • It’s a very dangerous poison and has to be handled carefully by veterinarians, and if not done correctly valuable animals can be killed.
  • Farmers couldn’t afford to drench any females, so halving the overall ‘Selection Differential’ (selection pressure) and slowing up genetic gain, despite the trait being highly heritable (about 25% or the same as fleece weight).
  • Selection on the ewe side had to rely on ‘natural challenge’ to the toxin, which varied greatly between seasons.
  • Commercial sheep farmers only bought FE tested rams after a bad season, and expected instant solutions the next season. They didn’t have a policy of buying resistant rams every year.
  • Farmers turned their purchased FE resistant rams out with their commercial ewes and expected to see rapid gains. This random mating approach could never bring rapid improvement.
  • Because tested rams were expensive, farmers only bought one or two, when they should have bought a team of rams to bring about positive change.
  • So, many stud breeders gave it away, as there was no profit in the business. Only the dedicated kept going to benefit their own flocks, which they certainly did. Now in bad years they hardly ever see a clinical case of FE.
  • With today’s knowledge and technology, success could be achieved in a quarter of the time.

How did FE resistance work?
  • Scientists worked hard to find out how resistant sheep could break down the toxin’s complex chemical structure in the liver, and get rid of it. It was a fascinating bit of detective work at Ruakura, which I don’t think was fully completed.
  • In simple terms, the sheep’s immune system did the work, so breeders were actually selecting for sheep with better genetic immune systems.
  • This is very interesting, as the pioneer breeders today (along with their ram buying clients), are finding their sheep don’t get grass staggers (another fungal toxin), and have fewer internal parasites as judged by less drench needed.
  • So to select against dags and worms, we need to identify sheep with a high natural (genetic) immune system, and manage them to allow it to be fully expressed.
  • It’s a simple objective and is really a repeat of breeding for FE tolerance, but in a very much shorter time.

Dags and worms – why fix them in this order?
  • Because this is the order in which they cause pain to the farmer.
  • With dagging you have to wrestle with sheep before staying bent over, to remove a worthless product. And then being in constant contact with faeces is also a health hazard.
  • Even if you have modern sheep handling equipment, physical effort is still needed and costs didn’t disappear.
  • Drenching is not so bad, as you stand upright but with no automatic drenchers invented yet, stretching and being bumped by sheep, and perhaps even being bitten are still hazards!

Are these traits inherited?
  • Yes they are.
  • The heritability of dags is around 25% and resistance to worms (also called host resistance) is around 23-25 %.
  • You will see ‘resilience’ used which is where a sheep can live with worms and still keep performing.
  • If this is a separate trait, (and scientists state that it is), we don’t want it as these sheep produce dags.
  • We only want sheep that are Worm-Free and Dag-Free.

Are the traits linked?
  • Technically, dags and worm resistance are separate traits so are not linked through common genes.
  • But there are farmers who have cleaned up the dags in their flocks (measured in barrow loads), and are finding that worms, (measured by the number of drenches given) are very apparent.
  • This may be entirely environmental and not genetic, but at this stage why worry – it’s saving work and money. So keep an open mind at this stage.

Breeding sheep to eliminate dags and worms. 2.

By Dr Clive Dalton

PART 2

Dag-Free & Worm-Free sheep – where to start?
Commercial sheep farmers have two options if they want to get rid or drastically reduce dags and worms:

Option1. Buy in the genetics (as rams) needed from established ‘stud breeders’.

Option 2.
Start a breeding programme in their own flock, which includes breeding their own rams.

Option1. Buy genetics from stud breeders.


Stud rams at public sale. FEC data are rare and Dag information non existent.
All rams are drenched frequently before sale.



  • Buying the genetics (as rams) from stud breeders seems the logical choice, as ‘stud breeders with registered flocks have been providing rams (and assumed genetic improvement) for commercial breeders since sheep farming began in New Zealand.
  • They record masses of data through Sheep Improvement Ltd (SIL) database via a number of bureaus.
  • But it’s often this mass of data that scares commercial buyers away. Stud breeders have all worked hard over many generations and none got rich from selling rams.
  • Few commercial buyers appreciate the costs, dedication and work involved in stud breeding.

Selection indexes

SIL Ram selection front page listing all the Indexes
There are 5 indexes and 11 Breeding Values provided.


  • The core of the SIL data provided to commercial farmers on the ‘ram selection list’ is in the ‘indexes’ and ‘sub indexes’, and there’s a range of them.
  • Breeding Values (BVs) are first calculated for each trait using all the information on the animal and its relatives.
  • They are then balanced up for varying genetic relationships between them and finally balanced for the relative economic value of each one. This is to achieve maximum overall gain expressed in cents.
  • See SIL website for details.
  • But geneticists never tell you how long it will take to see this overall and balanced improvement expressed in the index, in the bank account. Time is not built into the index – it cannot be.
  • The old genetic principle is well known – ‘that the more traits you select for, the slower is the rate of progress in any individual one’.
  • My concern is that today’s sheep farmers don’t have time to wait for these sophisticated indexes with all the various economic traits to bring about improved overall income, of which dags and worms are only a part.
  • If you want to fix dags and worms on ‘Fast Track’ because they are killing you and your profits, you need to hit them hard, and not let the rest of the index components slow you down.

This regularly scares ram buyers so they end up picking rams on their looks.



Special concern over dags and worms

The obvious conclusion: Farmers need to get rid of dags and worms on fast track as there’s nothing more important on a sheep farm right now.

Using ‘Independent Culling Levels’
  • We need to treat dags and worm resistance as ‘Independent Culling Levels’.
  • This is where you select for each trait independently (as they are unrelated), and if an animal fails to reach the pass mark for one trait (whatever level you set the pass mark at), then it fails the whole exam.
  • It’s like what the old School Certificate used to be – if you failed one critical subject like maths, no matter how good you were at the others – you failed the lot. It was tough.
  • Using the index approach, excellence in one trait can compensate for failure in another. This is not good enough to get rid of both dags and worms quickly – which is urgent right now.

The BIG problem:
Finding SIL breeders with Dag-Free and Worm-Free sheep
  • Very few SIL breeders have taken the option to select for host resistance to worms, and fewer still are selecting against dags to provide Breeding Values (BVs) for these traits.
  • This is understandable, as their clients are not asking for such rams. The new drench chemicals have now come along as the ultimate solution.
  • The BV for worm resistance (called WormFEC™) is based on a flexible protocol, (too flexible in my view) allowing great variation in FEC sampling times and methods, so accuracy for selection purposes has got to be a concern.
  • For those with WormFEC™ BVs, not all the lamb crop is always put up for testing, and this is often not made clear. So the choice of rams for sale within a flock can be very limited.
  • These BVs only apply within farms and not between them.
  • It would be hard to find a stud breeder who had not drenched the sale rams for at least two months before your visit. This is the minimal period needed to get an honest drug-free assessment of how genetically daggy individuals are.
  • Farmers are told by stud breeders, technical advisers and stock agents, that if they stop selecting rams for the main economic traits like fertility and growth (wool doesn’t worry them), then these traits will go backwards in their flock.
  • This is NOT true; they’ll just stay where they are, until selection moves things ahead again. You’d be hard put to select against these traits to start and lose them.
  • Ignoring the other main traits won’t drive you bankrupt for a couple of generations at least till you make a big dent in dags and worms.
Obvious conclusion: The choice of getting Dag-Free and Worm-Free rams from SIL breeders is very limited, so you need to look at starting a breeding programme in your own commercial flock.


Option 2. Start a breeding programme in your own flock.


What’s wrong with the idea?

Here’s some facts and fiction that you hear:
  • Fiction: Breeding is too much work and you’ll be buried in paper, stuck in the office when you should be outside – presumably dagging and drenching! Not true.
  • Fact: All you need to get started is some raddle and some tags (which may as well be numbered). Later on you may need to use your index finger!
  • Fiction: The genetics in your flock are not good enough as stud breeders have all the superior genes. Not true. This is biologically impossible.
  • Fact: If you’ve been buying rams from the same stud breeder for a number of years, you’ll have all the genes they have. Your flock will genetically be a couple of generations behind that stud.

The big positives

Sheep selected and bred on your farm will perform well on your farm.

  • You’ll be identifying top genetics in your own farming environment, and that’s a massive advantage. There’s no worry over whether a stud’s sheep will ‘shift well’ and adapt to your farm and management.
  • You don’t have to keep trying different studs in different areas to see which suits your environment. On your own farm – what you see is what you get, and you certainly can’t hide how much time and money has been spent on dagging and drench!
  • Also, because of the large numbers of animals in a commercial flock, there is a mass of scope for selection and culling, which many smaller studs don’t have. A high proportion of the ram lambs born in many small studs have to be sold as sires to make money.

PART 3





Getting started

  • To keep focused when reading further, have your own flock in mind to see what’s possible for you to do.
  • First: Have a slogan on a big card in the woolshed or in the sheep yards for all to see. It should say: ‘We breed sheep that are Dag-Free, Worm-Free & Sustainable’.
  • Keep quoting it and telling everybody you meet what you are doing, especially the stud breeder you have been getting rams from, your stock agent and especially your vet as your drench account will take a massive drop!
  • You’ll need a flock of at least 1000 – 1500 ewes to fast track initial improvement, and it probably wouldn’t be worth starting with fewer than 500 because of the selection pressure needed.
  • But give it a try with a smaller flock, and see how far you get; you may be surprised!

Essential features

First: To keep the job simple and avoid getting bogged in paper.
Second: To keep costs to a bare minimum.


Genetic theory

Thomas Bakewell in the 1700s used the principles used in this exercise to improve Longhorn cattle and Leicester sheep, so they’ve been well tested! He did it by ‘breeding the best to the best’. The challenge is to sort out what’s best. There are four basic ‘pathways’ to do this.


The four pathways to improvement

Text books show these in different orders but they're listed below in the best order to get started:

Pathway 1: Selecting females to breed females.
Pathway 2: Selecting females to breed males.
Pathway 3: Selecting males to breed females.
Pathway 4: Selecting males to breed males.

  • Pathways 1 and 2 put pressure on the females, and 3 and 4 on the males.
  • To maximise overall genetic gain, you must do both.
  • So often the only selection pressure is put on the rams, which is not good enough to see any great change in human years.

Forming an ‘A’ team of females (mothers)
  • To start on Pathways 1 and 2, find the best ewes in the flock as mothers of the next generation of female replacements, and to also breed males from them for use as sires.
  • These ewes need to be identified and kept as a separate ‘A team’ or ‘nucleus’ flock which will get intense selection pressure for traits that keep you in business.
  • Being Dag-Free and Worm-Free will top the list and so will their ‘easy care’ traits.
  • All A team ewes have to keep on performing to stay in the team, because as things progress, there will be plenty top prospects waiting to gain entry.

When to start looking for A team members?
You can start the programme at a number of times through the year, but it’s best when there are no lambs around to get in the way. Mid pregnancy is an ideal time to start.

for a genetic improvement programme.



Ewes at scanning

  • Identify (ID) the twin-scanned (TS) ewes. Mark them with a raddle that will last till at least lambing, run them separately, and feed them well.
  • Whichever is easiest, select the TS ewes out of the mixed age (MA) flock, or screen the two-tooths to find them.
  • The 5-year-olds are also a great starting point to find some as they have stood the test of time. Don’t be worried about the size of the nucleus at this stage; just get started.
  • Once you’ve got all the TS ewes drafted off, go through and throw out any you don’t like for anything you consider important.
  • Do NOT drench any A team ewes, or any ewes for that matter in the rest of the flock from now on. They shouldn’t need it and it only confuses the picture. Avoid any long-acting drenches like the plague.
  • f there is a health/welfare crisis (confirmed by your vet), only drench individual sheep in the A team, and mark them for culling later. Don’t be persuaded to drench the whole lot even if the drench specials are appealing!

Ewes between scanning and lambing



  • Cull any A team ewes that ‘pack up’, grow dags or have any health/welfare problems.
  • Be ruthless and ‘if in doubt – throw them out’ to tighten the selection pressure on them. To stay into the A team they have to measure up!
  • However, if the whole A team suddenly becomes daggy, don’t panic as that’s an environmental (feed quality) problem and it’s a good ‘challenge’.
  • Use it to ID any ewes that stayed clean during this ‘dag storm’, or got daggy and soon cleaned up. Give them a special mark. The ones that fail to dry up need a special mark too – for culling.

Ewes at lambing


  • Lamb the A team ewes separately and with normal commercial care. If this is ‘easy-care’– then carry on with your normal routine.
  • If you go around the ewes and see any that had trouble – try to remember them, or mark them for culling if you can catch them. If you can catch their lambs, mark them for culling too.
  • Again, be ruthless. Carry the raddle or ear markers at all times!

Ewes at docking of their lambs
  • Do NOT drench any A team ewes, or any others on the farm at docking. They should not need it, regardless of current drench promotions.
  • Mark for culling any TS ewe that didn’t lamb, was wet/dry or that had any other problem. Be ruthless!
  • If there’s a chance that these TS ewes may get mixed with the main flock after docking, and their scanning raddle may have faded, ID them with a numbered plastic tag. The cost is justified at this stage as you don’t want to lose them.

Ewes at weaning of their lambs


  • Mark for culling any A team ewes that have developed physical defects or failed to meet your standards.
  • Check udders, as you’ll be able to find any that went dry early or had mastitis. Teeth are also an obvious feature.
  • Be ruthless, especially on real dirty backsides that never dried up. How dirty is dirty, you’ll have to decide and set your own standards.
  • If you didn’t tag these ewes at docking, then give them a good permanent numbered tag now that you can read from a distance, as you cannot afford to lose these girls after all the work you’ve put into them.

Maintaining the A team nucleus flock
  • You need to decide how big the A team flock should be to provide the number of replacements needed to keep up the pressure on dags and worms.
  • A rough rule of thumb is to have about 7-10% of your total ewe flock in the nucleus. But be flexible at this stage.
  • Keep culling these ewes hard for physical defects and health problems, especially any that get daggy, have flystrike, are lame or have simply packed up.
  • Their problems won’t be all genetic, but be ruthless, as there will a genetic component to their ills somewhere, even if it’s not strong.
  • The target is structurally sound robust ewes with ‘constitution’ that can stand up to your management. If you have any doubts about a sheep, cull it.
  • YOU need to have great confidence in these sheep, as they’ll be great motivators for you and your staff as the programme proceeds.
  • In your doubting moments, go and walk through them and see if you’ve seen any better ones anywhere in the district.

What does it take to stay in the nucleus flock?
  • This is a vitally important part of the exercise. Apply the same simple rules used at the start of the programme.
  • To gain entry into the elite flock in the first place, or to stay there at any subsequent lambing, then a sheep must have completed all of the following:
Scanned twins.
  • Not been wet/dry at docking.
  • To have weaned lambs – judged by udder.
  • To have survived all the culling on constitution, health and structural soundness – and not caused any extra work or cost you money!
  • To have stayed free of dags, or dried up quickly after a ‘dag storm’ caused by feed changes.
  • Have consistently produced marbles or hand grenades.
  • Have had a FEC in the low hundreds.

Where’s the best place to find A team replacements?
  • If because of intense selection and culling, the numbers of ewes in the A team nucleus are now not enough, you may need to do another screening like was done to start the nucleus.
  • Two good age groups to screen for A team replacements to supplement the nucleus are
  1. The 5-year-olds as they have stood the test of time.
  2. The two-tooths as they have a long life ahead, and have already been subject to intense selection pressure.

PART 5

Two-tooth ewes from the A team nucleus
  • Now as two-tooths bred from the A team nucleus ewes, they should look a picture due to the intense selection pressure put on them up to now.
  • Apart from the odd sample to monitor progress, it’s not worth doing any more FECs, but keep on ruthlessly culling any that get daggy and don’t clear up quickly.
  • There would be no harm in doing a FCS now and again to check on any that are not measuring up, especially those getting daggy and not drying up fast.
  • Cull any that develop problems like footrot.

Planning the two-tooths’ mating
Decision needed: What rams are you going to join with these top two-tooths? They deserve very special consideration after all the work you’ve put into them.

Ram options

Option 1:

Stud breeders rams at pubic auction but few FEC records and no dag data.
  • Contact your nearest consultant from Sheep Improvement Ltd (SIL) by phoning 0800-745-435, or Email "mailto:help@sheepimprovement.co.nz" help@sheepimprovement.co.nz
  • Ask which breeders have rams for sale with WormFEC™ and Dag Score BVs.
  • Take care to check the records and ask the breeder how many rams have been tested and how this was done, as despite the SIL WormFEC™ protocol in the Breeders’ Manual (1994), some breeders have developed a few variations of their own.
  • FCS is not accepted by SIL as a correction for FEC. And in any case, the rams will all have been drenched regularly and recently, so you won’t be able to get a true ‘drug-free’ FCS assessment.
  • Beware that breeders may advertise that they are breeding for worm resistance or even worm resilience, but their programmes will need questioning.
Lab FEC raw data on rams at a sale - a very rare feature.
The FECs were not being used in an index.

Option 2:
  • Failing any success with SIL breeders, the next option is to look at any old sires you have on the farm purchased previously from SIL breeders.
  • This could surprise you or shock you - to see what you have spent money on (in all innocence) in previous seasons.
  • Their mature (genetic) immunity against dags and worms should have been fully developed – if they have any. It would be worthwhile having a look.
  • Make sure they have not been drenched for at least two months (preferably three) and first check their FCS. It’s not worth wasting $5 on a FEC if a ram is a scourer.
  • Any like this need to be used as terminal sires as you’ll be dagging their progeny for the next five years at least.
  • For the marblers or hand grenaders, get a FEC done.
  • Don’t contemplate using any animal with a FEC over 500 epg and zero should be a better target.

Option 3:
This is the obvious choice - to use your own rams, bred in the A team nucleus flock, and Pathway 2 describes this.

Breeding sheep to eliminate dags and worms. 7.

By Dr Clive Dalton

PART 7



These are the last two pathways where emphasis is on the males.

Pathway 3: Selecting males to breed females.
Pathway 4: Selecting males to breed males.


Pathway 3: Selecting males to breed females

  • This will happen by using the two-tooth rams bred from the A team nucleus ewes described in Pathway 2.
  • With all the selection pressure put on their dams, they are bound to be ‘improvers’.
  • They are your ‘power house’ for flock improvement, because a ram has greater genetic influence than any single female.
  • Their mission is to sire as many future females as possible in the flock to spread their genetic potential for resistance to dags and worms.
  • These rams are worth big money and if in doubt, ask yourself where you could buy better ones with intense selection against dags and worms?
  • Also, they have been intensively selected on your farm, so there are no worries about how their progeny will perform.
  • If AI had been a commercial reality, then this would have been the way to use them. But a lot can be done using single-sire natural mating.
  • Past experience has shown that really top rams can be single-sired mated with 400 ewes for one cycle. But using a top ram to mate 100 ewes is normal these days.

Pathway 4: Selecting males to breed males
  • This is the final genetic pathway and comes from using the male lambs produced by the top sires out of the A team ewes.
  • They will go around the loop again described in Pathway 2.

Inbreeding:
  • Inevitably the top sires of one generation will sire the top sires of the next generation, so a build-up of inbreeding is inevitable.
  • At low levels (e.g. under 7%) this is not a problem, but when it reaches high levels quickly (> 25%) then problems can be seen such as minor genetic defects like undershot jaw.
  • When levels get really high (> 50%) they can be major from ‘inbreeding depression’ where fertility and survival are reduced.
  • In this programme, a top two-tooth ram which finally comes through, when used on the A team ewes could have a dam in there, and a twin sister.
  • He could also have a number of half sisters (by his sire out of different dams) which he could also mate.
  • However, if this bit of intense inbreeding did cause problems in this early stage, the intense selection and culling programme would identify and eliminate them.
  • After a couple of generations of the programme, if there was cause for concern, then one single outcross to rams from a breeder with similar objectives would immediately restore genetic variation to continue making progress.
  • Another method for the long term is to divide the A team nucleus into small sub-flocks (on paper and with different coloured tags) and keep moving rams around these in a planned rotation each year.

Final points to ponder


  • There is no need to panic!
  • You certainly cannot go backwards genetically as everything you have done so far is positive! Sheep that don’t produce dags and don’t have worms are ‘efficient converters’ of their feed so are profitable sheep.
  • What you have done in your flock should be of great interest to your former ram suppliers, as now you have given them a challenge to come up with genetics that will reduce your animal health costs and increase ‘easy care’.
  • Invite them to visit your flock and show them the A team ewes and your sires bred from them. They can go home and plan how to keep your custom in future.
  • The wise ones won’t write you off, as you could have genes to help them in future!
  • For any vets complaining about your low drench purchases, suggest that if they want to keep on selling drench, they should provide a free dagging service with each container. Not many vets would ever have done a week's dagging!

What to do if you hit a worm crisis?
  • This could happen of course. An example would be an unexpected outbreak of Barber’s Pole (Haemonchus contortus) worms or some other species depending on where you farm.
  • Again, don’t panic as now when you use an appropriate conventional drench, because your sheep have never been drenched and developed any resistance, the drench will be highly effective.
  • You won’t need to keep on drenching.

NZ farm working dogs. A Heading pup's first year

By Dr Clive Dalton

Meg tied up at her kennel but 'on alert' - a good sign.
What would she turn out to be?
Her genetics were right - would her training complete the job?


MEG
Around the mid 1980s, Kevin Meredith, a farm manager and keen dog trialist got a new heading bitch pup, and I was keen to document her first year - the formative time in the making of a top working dog.

Kevin called her "Meg" and she had all the right genes from top ancestors, that had not only won trials, but had also come from hard working dogs on commercial farms.

These pictures I took of Meg's first year show the important stages of how Kevin provided the correct environment and training, so the dog's genes get every chance of full expression. It was all about getting the right balance between 'nature' and 'nurture' as the old saying goes.


Hello - what's that? A good sign of pup with a sharp eye.


Housing - cage or kennel?

This is an interesting question - is it better to keep a pup in a cage up off the ground, or tie it up at a kennel on the soil?

Most veterinary advice, for hygienic reasons, would go for the cage with slatted floor and no contact with soil, as in areas where there have been dog kennels for may years, there could be all sorts of infections around.

And of course dogs love to dig holes with a favourite spot being under the kennel. Some of these holes get so big that the kennel eventually falls into the hole, or in heavy rain it floats on the little lake like a boat!

Kevin's argument was simple - he always liked to tie a pup up at free-standing kennels as it gave him the opportunity to handle it more, and especially at the important time when you put dogs away after running loose. It was an opportunity to keep reinforcing the human-animal bond which is vital in successful dog training.

Dogs spend a lot of their time being tied up in their daily lives when out working so the sooner they learn to be comfortable with it the better. All working dogs have a short chain and snap hook on their collars to fasten them to a fence when they are temporarily not needed. Many dog handlers reckon it teaches them patience when they have to sit and watch other dogs working and not being allowed to join in until commanded.

The main thing it that it teaches the dog that going to be tied up is a pleasant positive experience, and not one to be avoided in case they get a reprimand. It's too easy to open a cage door and the dog runs in with no contact with the owner. Kevin's practice always seemed to make a lot of sense from the animal psychology point of view.

Make sure the pup's collar fits well so she doesn't learn to slip it.




Dominance of the 'pack leader'

An important part of this human-animal bond is to sort out right from the start who is the boss - who is going to be the 'top dog' in the hierarchy. Dogs and humans love boundaries, because they know that if they stay within them they'll be safe.

So having the pup on a chain, you can start regular lessons in dominance from an early age.

In the picture below you see Keven holding the pup's head up and holding his gaze into its eyes. It's a simple exercise once the pup has been tied up, petted and reassured with low voice tones. A few minutes each day is all that's needed. You can see from the pup's pose that it's a new experience for her and she's not liking it all that much.

This Kevin showed to be a very simple but very effective way to dominate a pup. He even used to to sort out a mature dog that was playing up.

All you do in this exercise is to lie the pup on it's side and calm it. If it struggles to get free - press down firmly with both your hands and calm it with low voice tones and a gentle massage. It's very effective and there's no physical violence involved anywhere. In the initial stages if the pup struggles, giving a low growl to imitate its mother's reactions can be effective.




Remove its food

Another trick used by Kevin and other dog handlers is to wait till the pup gets really stuck into a bit of meat, which it clearly considered its private property, and take if from it. If it gets nasty - give it the 'prone' treatment again and hold its meat in front of it before handing it over on your terms.





Teach 'Sit'

On the chain at the kennel, Kevin started to teach the first early lesson of 'Sit'. It was also part of the bonding/dominating experience for the pup and was a simple exercise of holding up the pup's head while pressing down it's back end on the command 'sit'.

This was done when the opportunity arose, e.g. when passing the kennels or after the dogs were let off for a run. Older dogs don't enjoy the overenthusiastic youngsters being let off at the same time but it is good for the pups to keep in social contact with the oldies who they could be working with in future.





The result seen in the picture, is a happy little fast-growing confident pup doing what dogs do - digging holes around their dens as they would in the wild. It means moving kennels now and again.


Hydatids
In the 1980s, to combat Hydatids which was also a threat to human health, dogs were dosed regularly by an officer from the local District Council. It was not a nice experience for the dog and they all knew when his van arrived - and what they were going to get.

The oral dose made the dog purge and the faeces were collected and sent to a veterinary laboratory to check what parasites were present.

Thankfully Hydatids has been eliminated and dogs are given pills every six weeks containing an anthelmintic to control the other main internal parasites of dogs.


Meg getting her first 'purge' dose - nobody liked this system

Vaccinations
Meg then had to have her injections for distemper and parvo virus - both killers of dogs. This was not as traumatic for her as it was a subcutaneous injection in the loose skin of her scruff. The veterinarian was my former colleague at the Ruakura Agricultural Research Centre - the late Tony Day.


Serious interest in work
There's often debate about the order in which you do things with a young dog. Do you put some commands on her before you let her loose with sheep, or do you just let her run free to develop her natural instincts and then teach the commands?

Kevin Meredith believed that the better option was to let the pup run free and then teach the commands. A good pup will quickly learn what the commands are, and almost understand why they're needed.

So here's Meg now about 9 months old with some of her first meetings with sheep in a confined space. The confined space is critical, as you don't want sheep to get the better of the pup. When you move to a larger area such as a small paddock, dog trainers always have an old experience dog handy to prevent any disasters such as sheep escaping and the pup not being able to get head them off. You don't want a pup to become a simple chaser of sheep.

You can clearly see Meg's genetics showing through. These rams are not going anywhere, as she keeps increasing pressure on them by moving in closer, and anticipating their every move.





Meg's further training
Kevin further developed Meg's skills by using her for light work on the farm as part of his team of dogs made up of older heading dogs and huntaways. So things were always under control and the sheep never won the day to shake a young dog's confidence. Top dog men like Kevin make sure a young dog is never over-worked and situations never get out of control.

Picture shows Meg off to work with a Huntaway team member on the right and the picture below shows the end of a working day where Meg has been part of the team.

Once a young dog starts to work it's important to keep them at it without overdoing it. A good stockman like Kevin Meredith knows exactly how to keep this fine balance, of avoiding both overwork and boredom. A heading dog is born to work - not watch others doing it.


Off to work

Time to knock off

Meg's first dog trial
Kevin was pleased with the young Meg and entered her for the 'Short Head and Yard' competition at the Waingaro dog trials near Raglan in New Zealand's North Island. She did well on the cast, the gather and the drive and as you can see on the picture below penned the sheep with no bother with plenty of force.


Kevin told me she was probably in too much of a hurry to get the job done to win, but he was delighted with her first outing. After the sheep were penned - Meg got a wee pat, and she was quite happy with that.

Top dog 'Meg' and top dog trainer and stockman - Kevin Meredith.
It's all about the animal-human bond and a dog trial is where you see this best.


A hard working life
In 2009 it was wonderful to catch up with Kevin again. He told me he had Meg for about 8 years before passing her on for an easier life. He reckoned she lived to about age 12.

What a great contribution she made to farming - one of the many unsung heroes of her kind. Loving her boss, always wanting to get off the chain to work, hating day's off, and happy with a pat or scratch behind the ear after a hard day's work.

Imagine how many man-hours she saved in her 12 years of work, and what financial value you could put on it. Imagine how many kilometers she had run too in that time?

Communicating with farmers – Getting your message across

By Dr Clive Dalton
Clive addresses a crowd of farmers and MAF staff at a Lands & Survey Angus field-day in 1976.

Farmers constantly need new information
To keep farmers and their staff up to date with new developments, good communication is essential by the many technical people, (consultants, farm advisers, sales and advertising people) who have information to impart.

Measuring efficiency
It’s very difficult to measure the efficiency of communication, without testing the recipients to see how much has been learned and acted upon. What many in the information business know, (but rarely admit or measure), is that communication is generally a very inefficient business.

No formal training
Few technical people who have to address farmers, have had any formal training in the craft of communication, and you would be hard pushed to find out where to go to get any. It’s a case of learning on the job – which may include not much ‘learning’. The result is hours of wasted time and money
Rarely do we ask anyone in our audience after a lecture or talk for an honest assessment – and if we do, they give us what we want to hear!

The good and the bad
Most folk looking back on their school, college or University days would be hard pushed to find more than 5% of those who stood in front of their class, as brilliant communicators. This is a frighteningly waste of peoples’ learning time when you think of it.

How few people do you hear say they were ‘switched on’ to a subject by a brilliant teacher, but how many more quote how they were ‘switched off’ a subject by some awful teacher? Maths would have to be top of the pops for this.

Key points if you have to give a talk
There’s a mountain of books on communication – a few readable and helpful, but most full of jargon and theory, and impossible to finish. The books have a major communication problem!

What follows are a few points, gleaned from many sources and from my personal suffering at the hands of others, as well as guilt over what I may have inflicted on others. They are some issues to think about if you have to give a talk, and if you want your audience to learn something.

What’s your aim?
Get this very clear right at the start. When you walk out the door after the talk, think what have you left behind in the minds of your audience? What did you set out to do?
  • To inform
  • To entertain
  • Provide a bit of both - “Infotainment”
  • Be memorable – will they remember both you and your message?
  • Provide value for money if they have paid!
The chance of success
This is a bit scary, but face the truth! It’s old news but is frequently forgotten. So you can see how your effort has to be allocated.
  • 7% is WHAT you say
  • 33% is HOW you say it
  • 60% is the ENERGY you used in saying it
Clearly, dull people and a dull talk cannot get a message across, no matter how good it is!

Message retention
This is also very scary. It’s amazing how many people sit through a talk, and think all the information will be in their heads after the talk for ever. It probably is, but it cannot be recalled and with age things get worse.
  • You remember only 25% of what you HEAR by the next day.
  • By the next week it would be about 5% if you were lucky.
  • Adding visual messages increases the retention rate.
  • Adding smells will increase it further!
  • Success depends on ‘listening skills’ – which we are not taught.
So the lesson is that you have to do a really good job with visual aids.

How to get it wrong?
These sins are far too common –but the last person to be aware of them is so often the speaker, and nobody tells them afterwards so nothing changes!
  • Too much information – tell them the least your audience needs to know.
  • Too little – no meat in the message.
  • Wrong place – it was impossible to learn in the environment. The speaker was not aware of how bad the conditions were for the audience.
  • Wrong time – nobody could learn at the chosen time of the talk for many reasons.
  • Above their heads – no chance of anyone understanding the message.
  • Boring – dull enough to make everyone beg for it to end.
  • Speaker not aware of the time spent so the meeting over-runs.
  • Poor chairman not doing his/her job – eg keeping speaker and programme to time.
  • Insulting audience’s intelligence.
  • Telling the audience what they already know– so wasting everyone’s time and somebody’s money.
How to get it right?
  • Wear your client’s shoes (gumboots)!
  • Check the venue. Will everyone in your audience be able to see and hear?
  • Check the seating – how comfortable are the seats.
  • Check visual aid equipment – have spares.
  • Check sound equipment – have spares.
  • Get a friend to sneak around the venue once you have started speaking to see everything is going OK.
  • Watch your audience’s behaviour – bad signs are people sleeping, sitting with head in hands, looking at the ground or the ceiling, fidgeting trying to get comfortable, clock watching, exhaling loudly, gasping for fresh air, talking to person in next seat, and walking out! Many speakers never notice these – believe it or not.
  • If the chairman doesn’t get people (who have sat for more than an hour) to stand and stretch, YOU take action and make them stand up. Don’t let them out of the room though!
How do we learn as children?
This is a vitally important issue, as so many people seem to think that when we grow up, we can put up with appallingly bad communication that you would never inflict on an innocent child! As mature beings, we learn the same way as kids do! We all crave for a talk that is:
  • Interesting
  • Relevant
  • Clear & simple
  • Rewarding
  • Entertaining
Who is your audience?
This is closely linked to the question of what is your aim. You are lucky if your audience is made up of people with identical interests, but even then, they will vary because of the points shown below. You can’t do much about this, other than be aware and try to modify your message.
  • Age
  • Sex
  • Leading busy lives – so time is precious.
  • Interest in the subject
  • Educational background
  • Social status
  • Religious & cultural status
  • Tiredness
  • Hungry –low blood sugar
  • In need of a smoke –agitated
  • Comfortable – how long have they sat on hard seats.
Profile of a 16-year-old
As a tutor approaching retirement, I was very aware of being horribly out of date when I had to teach young farm trainees straight from school who were from generation X and Y.

Now we are on to generation Z which are very different again. They need more guidance but they certainly know their rights. But I was amazed how few folk I talked to in the farming industry (especially employers who didn’t have teenagers), had thought about these issues. They judged 16-year-olds by what they remember of their youth.
  • Two thirds are from split homes. (Ten years ago this was one third).
  • They come from class sizes at school of at least 30.
  • Their concentration span is very short - max of 3-5 minutes – the time between TV ads. It used to be 5-7 minutes.
  • Low discipline levels in schools. Class disruption is normal.
  • Students want to talk continuously – they have been taught in groups and encouraged to talk so they don’t see a problem.
  • At school, they have been encouraged to work in groups which is good. However, sitting listening for periods of more than a few minutes is very hard for them, so they miss vital information only told to them once.
  • They can learn among noise, which in today’s world is also very good.
  • The love loud throbbing music – especially inside a vehicle or restricted space.
  • Teachers have had little time to help anyone with individual learning problems. Disruptive students get attention (that’s why they are disruptive), but quiet non-achievers in class can easily pass through the system having learned very little.
  • Many have a negative attitude to formal learning which is not their fault.
  • Little or no encouragement received from home for academic learning –in fact there could have been positive discouragement.
  • A large proportion will have no NCEA subjects due to lack of motivation and boredom.
  • Boredom is the main disease of high schools. The school system had betrayed them!
  • Many will have one or two NCEA subjects - generally not in academic subjects. Some may have done sixth form but not got any qualifications.
  • They are active people who like practical subjects.
  • At least twenty percent of them will smoke –and few will want to stop.
  • About 3% will have serious learning problems (ADD), and won’t be able to concentrate. They stop their class mates learning.
  • They all know about drugs and have seen them in primary school.
  • A very high percentage will have used them by secondary school and will be very knowledgeable.
  • So drugs in the workplace are now a normal part of the daily environment.
  • Poor literacy - many have reading age of 8-10 years or worse.
  • Maths ability is good with money, but they cannot do any sum without a calculator, even divide 1000 by 10. Mental arithmetic is beyond them – they are just not taught it.
  • They have fantastic finger dexterity, keyboard, computer and mobile phone skills. They can text without looking at their keyboard and while their phone is hidden in their pocket.
  • They walk around with a phone permanently in their hand, texting and checking for incoming texts with one hand. The other is for work!
  • Ninety percent are males with strong male stereotypes and attitudes to hygiene and pain.
  • Ten to twenty percent will have already had a driving conviction.
  • Twenty percent will be driving cars with no WOF or insurance.
  • Five percent will have hearing impairment from loud music.
  • They are growing rapidly and are always hungry.
  • They are high on testosterone and oestrogens.
  • Most will be sexually active - or they’ll tell you that they are!
  • Few are capable of a hard day’s physical work that a grown up can handle.
What makes communication difficult?
The theory talks about a ‘message’ which is ‘coded’ by a ‘sender’. This then goes to a ‘receiver’ who ‘decodes’ it. The three things that ruin this process are:
  1. Competition for your message from other messages.
  2. Bad coding by the sender and bad decoding by the receiver.
  3. Information overload at both ends.
Competition for the message is a major hazard. We ask why folk who came to our talk have done nothing about the message they took away so enthusiastically? The answer is simple - when they got home, there was at least 5 new issues that had blown up which needed urgent fixing. After that, they’ll have difficulty remembering when they attended your talk, what your message was and even your name. Ask some university students to give the full names all that lecture to them. The answer in communication terms is scary.

So you can see the value of a ‘take-home’ message that doesn’t look like junk mail and that they’ll keep (or their partner will keep) and not file in the bin.

Prioritise your message
This is very important as it stops your wasting your time, and more importantly, their time. Sort out what are your audience’s wants and needs (they may be very different).
Get this order of priority right. If time is short, cut number 3.
  1. Must know?
  2. Should know?
  3. Nice to know?
  4. Questions and discussion
Never, ever, cut out number 4! That should be THE highlight of your talk. If you are running out of time, cut out number 3 and go straight to 4.

The brain plays tricks
Speakers who make you ‘suffer’ their presentation regularly forget these basic points.
  • Our concentration spans are short – and getting shorter thanks to TV advertising.
  • The brain can cope with many issues at the same time, so our thoughts wander all over the place if what we are hearing is boring or deemed by our brains to be unimportant.
  • The brain works mega times faster than speaker can speak, or read words to us from a slide - which so many insist on doing.
  • The brain filters out things that it may consider unimportant.
  • The brain is lazy and smart (both at the same time) so it looks for the easy path.
  • It’s always interesting and a bit alarming when you ask someone who has been to a talk or presentation what they learned. Most will be struggling to give you a detailed account – but they’ll all add it was a good meeting.
Our brains differ – 7 intelligences
This too is well known and is a major reason for so many folk failing. We have different kinds of brains, and sadly for some, their’s cannot be accommodated in a teaching regime. The only hope is for individuals to do more themselves to cope, as teachers have enough problems!

Be aware of this as a learning strategy for yourself, and recognise it when you need to teach. From the list, find out which one(s) you are, and try to recognise what some other folk may be, especially those you have to communicate with.
  • Mathematical
  • Musical
  • Physical
  • Visual
  • Linguistic
  • Intra personal
  • Extra personal
A very sad tale
I had a 16-year-old farming student who could not pass one written test of the simplest questions – even on the third repeat. In fact, the more repeats he got, the worse he got. Yet on a bus trip of well over an hour, he sang the complete works of the Australian bush balladeer ‘Kevin Bloody Wilson’. His mates assured me he was word perfect! The lad had a musical brain, which I could not handle, as I couldn’t put my lectures to music with three expletives in every line. Sad to say, he was killed in a railway crossing accident when the train hit his tractor.

Six stages of learning
The books tell you this is the way to learn things. It’s also useful to know when you are teaching so that you can make the learning by your listeners easier if they need to remember things. You do things in the following order:
  1. Get set
  2. Get information
  3. Explore
  4. Memorise
  5. Show-U- Know
  6. Reflect
The major problem I found when teaching farming students (16-17-year olds) who had hated school, was that they had never been taught to learn. So they sat during class with arms folded, listening, enjoying the discussion, but assuming that they’d remember all they heard. They didn’t realise that for most of us, learning needs some kind of effort.

I had to make them write some things down and draw diagrams – to do something physical, as they had not learned (or not been taught these skills). The would ask me 'have we got to write this down'?

 As a result, they had nothing to use for 'revision' which they had never ever been shown how to do, and hence failed in any written tests. These students had fantastic practical skills, so their school record showing low achievement was so wrong! The education system had failed them.

Mind maps
I gave up on talking and expecting them to 'make notes'.  At University with many lecturers that's all you did - try to write down everything they said hoping that it would make sense when you re-read them. It rarely did!


Mind maps like the example above were my salvation and the students' too. You can see from the above example that we discussed everything that had to be done to prepare for calving.  We both learned so much from sharing information and experience – without the chore of them having to write many words down. It kept all our brains active, and by turning words into a picture, it was had high recall, which I proved by asking them to draw a mind map to answer questions in exams.

I used to hand out large A3 sheets so that they could keep the finished map to bring out in future years to work on with their staff before calving.  Different jobs could be allocated to different people and nothing slipped through the cracks.

These same students would struggle to write 50–100 words as an answer, but could  fill a whole A4 sheet with detailed information as they had very good recall. Communication had worked. 

For more information on mind maps - Google <‘mind maps Tony Buzan’>

Written words and spoken words
These are so different in terms of communication efficiency. Apparently with texting and emailing, more words are being written today than at any other time in history. But they are very different words to those used by anyone who sets out to write a handout, or god-save us, a manual!

You have to stop yourself writing ‘hard to read’ English in anything you give to a modern audience. Your only chance of getting anything ‘browsed’ is to write it in ‘spoken’ English or journalistic style.
  • You need to become a good browser and the trick is to only read the first sentence of each paragraph. Here are some interesting points that have been around for a while.Humans communicate best with sound.
  • Most visual image fades in 1 second – unless they are spectacular or shocking.
  • Sound memories fade in 4-5 seconds – again unless they are spectacular of shocking.
  • Voice tone gives “emotional impact” that no picture can do.
  • In journalism we strive for “colour” in our written words to try and imitate the spoken word.
  • Monotone is a killer – if the voice is dull, then our brains assume the speaker and the subject is dull too.
  • Ums, Ahs, Eh’s, You-knows, etc can kill listener concentration – listen to yourself on a tape, or view yourself (in private) on video. The shock can be overwhelming!
The handout
Handouts used to be considered important for the take-home message, but we know that most of them end up as junk mail, as there’s so much other material around of very high quality. So class handouts as a ‘nice’ idea but don’t rely on them being effective after your talk.

A good idea is to hand them out during the session, so keen folk who are trying to take notes can just highlight key parts as you go through.

The take-home CD, video or DVD
This is the latest idea, but again how many folk have time to sit and watch them – even if they know how to work the player! There used to be a figure when video recorders came out that at most, only 9% of recorded videos were ever watched. Thing won’t have changed.

The ‘slide’
Once upon a time we had projectors and 35mm slides. These were made from the colour pictures we took, but we also made stencilled words into 35 mm slides.

Then came the Overhead Projector (OHP) with a pack of multi-coloured pens, all of which we used, even if some like the brown and yellow could not be seen!

Then came the laptop computer and the digital projector with 'Microsoft Power Point'.  This is my view is death to communication!

The technology is not to blame for poor communication – it’s the way it’s been used which is the problem. What has happened, and is still going on because it’s easier with computer software, is that speakers are still producing ‘slides’ and abusing them rather than using them in their talks. Here’s what happens:
  • The slide has too much information. The rule is to have a maximum of five lines and five words per line.
  • The speaker reads the words on the slide out aloud to the audience – who can also read – and a hundred times faster than the speaker can read.
  • The speaker is simply using the slide as a memory jogger. This is now a worse problem as Power Point makes the production of slide so easy. People are typing out their talk in Power Point which we then have to endure.
  • Power Point also allows you to use fancy gimmicks, which fortunately many folk have not learned to use yet! Others go crazy with them which distracts from the message.
  • These slides go on forever and the meeting over runs, so there’s no time for discussion or questions. How often has the last speaker been asked to cut down their time because the chairman has failed in his/her duty!
  • Speakers should NEVER be allowed to over-run by chairmen.
Back to the board – why not?
Consider going back to basics. There was nothing wrong with the old blackboard (apart from chalk dust and finger nail scratchings), and the whiteboard (apart from pens that don’t work and permanent markers) provided that, it was in the hands of a skilled operator.

The big advantages are:
  • When you use a whiteboard really well, you cannot help being active. It’s hard for people to fall asleep or their minds wander off, when the speaker is leaping around and you are watching for the words or pictures to emerge.
  • You are actively combining words (from your mouth) with pictures (from your pen).
  • Rubbing out words provides action in anticipation for new ones, and gives a sense of progress through your talk.
  • It’s a good idea to write a sort of ‘menu’ for the talk down the side of the board before you start, and wipe bits off when finished. It makes the audience feel they are progressing towards the end – always an attractive destination in a talk.
Points for success
  • Double check the pens – always keep plenty of new ones and don’t lend them to anyone.
  • Check the caps have been tight, and get into the habit of always putting the cap back on while speaking.
  • Avoid green, and only use red for emphasis.
  • Check no ‘smartass’ has slipped a permanent marker into the set of pens. If you need to remove it, go over it with a proper whiteboard pen and rub the lines off straight away.
  • Make sure there is a cleaning cloth or duster.
  • Don’t stand in the one position all the time, as some in the audience may not be able to see. Check this out before and during your talk and make people move (nicely) if you find it easier to operate from one spot to avoid blocking their view.
  • Use mind map (see above).
  • The brain likes colour too – but don’t overdo it. Use colour to underline and highlight key words in your mind map.
Final thoughts
All you have is this – in any order:
  • Be simple
  • Be clear
  • Be brief
  • Be entertaining & be memorable
Fast track to improvement
If you want to improve your presentations real fast - just arrange to have your talk videoed. But view it in private first, as you can be devastated with the result. You will see things that you cannot believe you did!

At the end - for goodness sake END!
Some folk find ending very hard - they seems to get a pain when they have to sum up- so keep on to avoid it. Don't be fooled (if you are chairman) by  words like ‘finally’, or ‘to summarise’ or ‘to sum up’ which lifts the listeners’ heart, and then the speaker’s brain seems to find another thread.

The trick I find that works every time is the chairman - to dive in when they are drawing breath between sentences and say in a really loud voice over the microphone - 'And FINALLY'! They are so shocked, and the audiences laughter so spontaneous,  that they say - 'Well I'll stop there Mr Chairman"!

Yorkshire advice
Yorkshire folk are noted for their thrift with money, time and words. They have this advice for public speakers which is well worth remembering:
1. Stand up
2. Speak up
3. Then SHUT UP!
