NZ Shearing Sheds Construction or Renovation 1981

Introduction by Dr Clive Dalton

Getting information to farmers that they could understand and use to improve their profits, was the main driving force for all of us who worked for the New Zealand Ministry of Agriculture & Fisheries (MAF) in the 1970s to 1990. Our ‘Information Services' section was staffed by top agricultural journalists, and we had radio and TV producers the equal of any in the commercial world.

The core for the printed information flow to farmers was a series of fact sheets called 'AgLinks' developed by Geoffrey Moss, a former Farm Adviser, especially well respected in Taranaki, who headed MAF Information Services.

Geoff was awarded an Eisenhower Fellowship to visit America and came back with the AgLink idea, to get research information from scientists to farmers, horticulturalists and their advisers, in brief ‘fact sheets’ that were easy to read, easy to file – and were free! The were an 'information link'.

Geoff appointed Colin Gardner as the first editor – a kiwi Sheep and Wool Instructor who had come back from working in Australia. Other top agricultural journalists, editors and people like me in the different MAF regions, joined the team, which started work in 1969.

We sourced topics for AgLinks and did the first drafts, which our Head Office editors fixed up and got printed for distribution either from the Wellington Head Office or through each MAF local office.

We ended up with well over 1000 topics, and we printed and gave away thousands, from which farmers could build up into sets on different topics. The sheets were colour coded to make this easy.

The aim was that if a farmer had a question – MAF needed to have an AgLink to answer it - and we did. We were farming’s Google before Google! Clearly the concept was well ahead of its time.

Shearing Sheds - plans and construction details

A classic example of the value of AgLinks was the series on Shearing Sheds written

by Lindsay Galloway, who was the highly respected Sheep & Wool officer in the MAF Christchurch office. Lindsay drew all the plans himself and had them checked by building inspectors from the Ministry of Works.

Lindsay says that as he travels around Canterbury and beyond in his retirement, he can see the results of his 40 year's service to the New Zealand sheep and wool industry still standing proudly on farms, many of which don't run sheep now and have been adapted for calf rearing with the change to dairying.

Lindsay also worked to help sheep farmers on the Chatham Islands where many of his sheds were built, and have withstood the challenging climate there.

Linsday Galloway’s Shearing Shed AgLinks are still as relevant today as they were when produced, and are invaluable for anyone wanting to build a new shearing shed, or to repair or modify a facility that has fallen into disrepair.

The death of AgLinks

AgLinks were dumped in 1989 after a failed attempt to charge for them by the ‘new MAF business managers’ who saw the end of MAF’s dedicated service to farmers. All Head Office copies had to go to the Wellington landfill, but some of us in the regions pirated a set. The National Library holds an incomplete set.

Sheep yards: Design and Construction details

By Dr Clive Dalton

Set of sheep yards to handle 1500 sheep built at the Whatawhata Hill Country Research Station by Farm Manager Joe McLean in 1980s.
They were based on the MAF Bulletin 353


Sheep are smart animals

If you try to keep sheep and you don't have decent handling facilities (pens or yards), then you will soon start to hate them and declare that they are stupid animals. Nothing could be further from the truth - as it's YOU that has the problem and not the sheep.

Sheep in modern times
In today's world, most countries where sheep contribute to the national economy are finding that 'labour' is a major problem. Young folk don't want to work with livestock on farms, and the existing population of sheep farmers is rapidly aging and are not capable of the physical work traditionally associated with sheep - most of it involving bending over animals or lifting and dragging them.

Sheep farmers are notorious for back and knee injuries from sheep handling and shearing, and this is a major cost to the nation.

Sheep instincts
Sheep have two major instincts which if exploited when designing handling facilities will make life so much easier. These are:
  1. Sheep are a 'flocking' species. At any sign of panic they flock together for safety rather than run away in all directions for self preservation.
  2. They are also a 'follower' species. A sheep loves to follow another sheep, and lambs from the day they are born follow their mothers and stay with them, unlike goat kids, calves and fawns where their mothers hide them in a creche. They are a 'lying out' species.
Things to avoid
So the two above features of sheep behaviour are the core of good sheep yard design, to avoid the physical effort of pushing, catching, holding and turning sheep over as this is where human backs are damaged.

Large and small flocks
The size of flock doesn't have much influence on basic sheep behaviour. Obviously as flocks get large, it's harder for an individual animal to know where it is in a mob if the scale of the facilities are not increased to cope.

Information sources
The biggest demand of late in New Zealand has come from small 'lifestyle' farmers who need some handling yards for a few sheep.

New Zealand Reference book
The classic NZ publication is called 'Design and Construction of Sheep-drafting Yards' published by the NZ Ministry of Agriculture as Bulletin 353 in 1951, and revised in 1956 and 1962. The author was J.E. Duncan, Chief Advisory Officer (Wool), Department of Agriculture, Wellington.

The price was one shilling and six pence!

I have created a free PDF version of this treasured archive of sheep farming information which you can download by clicking on this link to online publisher Scribd and following the instructions: http://www.scribd.com/doc/71774584/Design-and-Construction-of-Sheep-Drafting-Yards

Design and Construction of Sheep Drafting Yards

Here's what J.E. Duncan wrote in his 1951 introduction:

'Over a period of years the volume of inquiries for plans and specifications of sheepyards and their accessories has shown that there is always a demand for this information. Some inquiries are from young men just starting on their own and others are from established farmers adding to or rebuilding their existing yards, but whatever the reason the demand seems to be increasing. This bulletin aims to supply basic information covering most of the questions usually raised'.

A marvellous book that has served generations of farmers, and is still serving farmers from all around the world in the 21st century.
