East Friesian importation 1992

From trials undertaken by MAF’s Research Division after the first importation of exotic sheep in the 1970s, the East Friesian x Romney cross looked very promising in the early stages of multiplication. 

Here is a summary of the main events relating to the East Friesian importation as reported in Dr Jock Allison’s paper:

·    Jock visited Turkey when working for the UN and took the opportunity to visit Sweden (in addition to the Israel) which Dr John Hellstrom the Chief Veterinary Officer of MAF had suggested was likely to be an acceptable source of animals for importation.

·      John Hellstrom was also a friend of the Swedish chief sheep veterinarian Dr Asa Lindqvist who was of major assistance in putting the whole Swedish programme  together. 

·      Dr Stuart MacDiarmid MAF’s chief advisor on Animal Imports was also very helpful, as Jock’s company grappled with a number of problems through the importation. 

·      The company traded as Silverstream Ltd with two thirds owned by Jock and Hilary Allison and one third by Russell and Tricia Hamilton.

·      The development of the import health standard was pretty quick and incident free, and things were ready to get going in the second half of 1992. This programme was a joint venture with 2/3rds owned by the Allison family. 

·      Jock traveled to Sweden to select, purchase and pre-quarantine sheep before their transport to New Zealand. Having selected the animals, the source flocks had to undergo a series of tests prior to assembling the group for a period of isolation and additional health testing.

·       Unfortunately the biggest East Friesian flock in Sweden had a very high incidence of Maedi visna (a slow virus disease) and no animals could be selected. This was disappointing but disastrous for the flock as they could no longer trade animals even within their own country.

Problems with transport to New Zealand

·      Having assembled the 11 pregnant ewes and 4 rams and the pre-quarantine going well, MAF Import Section veterinarian Vaughan Seed would not approve any air route from Frankfurt back to NZ, in spite of the company having approval for this in June 6 months previously. 

·      This refusal caused considerable panic as Jock tried every alternative route. It was possible to ship the animals to England, as their veterinary authorities would not allow the animals into the UK while they waited for a flight from Heathrow to New Zealand. 

·      Routes through the USA with various carriers were tried, and the situation was getting serious. Close to Christmas Jock’s team had to book airfreight which was difficult, as in Sweden ewes more than 4 months pregnant were not allowed to travel and if this went beyond Christmas, all travel for the ewes would be off.

·      Jock found Seed’s attitudes hard to fathom and had many arguments with him, which resulted in visits to higher levels (the Chief Veterinary Officer Peter O’Hara and the Beehive) to resolve. 

·      The answer was political and Jock urgently contacted Warren Cooper the National MP for Otago and also a government Minister, and a meeting was convened in his office in December.  Jock’s wife Hilary orchestrated things for the company and she and Russell Hamilton travelled to Wellington, as did Jill Jones their transport agent from Auckland, all at the company’s expense of course. As they got off the plane they were paged in the airport with a message from MAF that they had approved the air route for the sheep. 

·      The meeting still went ahead in Cooper’s office with the MAF officials, who were exhaustively asked if they were sure that there were no other matters which were of concern regarding animals coming to new Zealand.  The planned trip for the sheep was from Auckland airport to Somes Island for a month’s quarantine, before they could go down to the company’s quarantine at Mosgiel. MAF gave assurances that all was well when Minister Cooper swept into his office and asked ‘are my people happy’?

·      While still in Sweden Jock had to arrange for a travel crate to be built to transport the 15 sheep, which was negotiated by phone with German authorities that assured him that they knew everything about animal transport crates. 

·      Jock had doubts, as first they had to travel by truck about 350 km from Kalmar to Stockholm ready to catch a freighter to Frankfurt where they would then catch an Air New Zealand plane home. Chips Jones a MAF vet travelled to Sweden to accompany the sheep (and Jock) back to NZ. 

·      Jock and team got to the freight depot at Stockholm and met the transport crate, which had come up from Germany. There were problems but Jock was prepared. The feed trays were about 150mm wide and had a 150mm vertical lip so the sheep couldn’t get their noses in to feed. There were surprised looks when Jock got inside the crate with a hammer and chisel and proceeded to knock the feed trays into shape. 

·      From leaving the pre-quarantine barn it took 83 hours before arrival in Auckland at about 1.00am on Christmas morning. Jock’s team had had about 5 hours sleep in Frankfurt and a bit on the plane and on arrival in Auckland it took some time before he could get around to where the animals were to be unloaded onto a truck for their trip to Wellington and on to Somes Island by boat. 

·      On Somes, the ewes wouldn’t come out of the crate and the MAF livestock officers were poking them in the guts with a broom. Jock took exception to this as the sheep didn’t appreciate being poked when heavily pregnant and worth $20,000 each. Someone lent Jock some overalls, and he climbed into the crate and the animals trotted straight out onto the truck. 

·      The company specified that the ewes and rams had to be separated by a gate on their trip to Somes, but the MAF’s Livestock Officers at the airport knew better and after a serious disagreement they refused to allow a partition to be put up. The result of this was that the rams nearly killed a ewe that had had problems on the flight and was not well on arrival. But Lock says the Somes Island MAF staff did a terrific job with this ewe, and indeed with all the sheep as they lambed safely in their first month after arrival.


Quarantine Costs on Somes Island

·      Jock remembers that the cost of the animals in quarantine was about $11 for bed and breakfast per day for each animal, which was high enough and the company had signed a contract to that effect. The animals were released from Somes at the end of January 1993, and Jock says an account subsequently arrived from MAF for about twice the expected price. And in addition, the lambs were charged at the same rate in spite of them being very young and on their mothers. 

·      Jock asked why the cost was so high and the reply was that MAF staff had worked a lot of overtime with the lambing ewes. The company maintained that it was logical to have either an agreed daily rate for the animals, or a piece-rate where the hours would be charged. MAF couldn’t have it both ways, and charge a daily rate plus overtime - it wasn’t logical. Also Jock suggested that the ewes were looking after their own lambs and these lambs should not incur cost. 

·      MAF lawyers got in on the act and typically added to the confusion, and the company eventually paid the daily rate for all animals but no overtime! 


East Friesian sales and distribution

  •       In 1996, after the East Frisian purebreds got out of quarantine, 50,000 ewes were inseminated with frozen semen.
  •       30,000 straws of EF semen were sold at $35 each.
  •        20,000 ewes were inseminated with fresh EF semen.
  •        Romney breeder Derek Daniel and Coopworth breeder Ron Cocks purchased 8000 EF semen straws between them.
  •        In 1996 50 EF rams were sold for an average of $20,000.  
  •       A package of 10 ewes and 8 rams was sold to PPL Therapeutics for $400,000.

Release from quarantine

 The East Friesian quarantine programme at Mosgiel

·         From Somes Island the EF animals went to a quarantine area the company established at Silverstream near Mosgiel, and lived there for the next three and a half years. From the 11 ewes and 4 rams imported in December 1992, the company had 580 animals ready for release to industry by March 1996. 

·      Only animals derived from ET and born from recipient ewes in another quarantine area were allowed to be released. John Bolger was the company’s allocated MAF veterinarian and proved to be pragmatic and helpful at all times.

·       The multiplication programme went well. Ewes lambed in January to March 1993, and were treated with hormones to get them pregnant again to lamb in November of the same year. 

·      Embryo transfer programmes allowed lambs to be born on the secondary quarantine in 1994 and 1995. Previously in 1994 the company joined some Romney ewes with East Friesian and Border Leicester rams to enable a comparison of EF crosses with the most common crossbred available in NZ. The very marked superiority of the EF crosses, plus the fact that the company could show the animals to many interested sheep farmers who visited the quarantine station was a major part of the marketing strategy. 

·      Throughout the quarantine period the company kept up a strong communication programme with industry, and had thousands of visitors to the quarantine unit to observe the animals and their crossbred progeny, all of which built up demand.

An Early Release Date of EF sheep

·      Import conditions required the inoculation of kid goats with mesenteric lymph node material recovered from the imported ewes, which were the first donors for embryo recovery, and transfer into recipient ewes which were in the company’s secondary quarantine. 

·      The company had a stipulation that these kid goats should be kept for 3 years from the date of inoculation. Because of the very large udder development in the East Friesian ewes, it was early April 1993 before it was possible to operate on these ewes to recover the lymph node material for the inoculations. 

·      Jock said that the scientific literature indicated that 12 months was the expected time by which they could expect to see the manifestation of Scrapie in the sentinel goats, if there happened to be any in the imported animals. 

·      By waiting the 3 years the company would have missed the 1996 breeding season in the North Island, and there was clearly a significant demand for the sheep. So the company submitted a case for early release to the Maximum Security Quarantine Advisory Committee (MSQAC), and prior to this meeting they submitted a case to Meat Board and NZ Stock and Station members of that committee. Both neglected to turn up, and consequently the MSQAC’s view was a unanimous NO!

Economic implications of quarantine rules
·      The company had already spent about $2 million, so the committee’s decision had major economic consequence as they could not meet North Island clients’ requirements. 

·      The stupidity was that (a) MAF agreed with the company, (b) most of the industry agreed with them, and (c) there was no scientific evidence which suggested there was any disease risk of a release 21 days shorter than first defined.  And yet the relevant industry consultation committee did not agree.

·       So the company made another case and lobbied all the committee members, and shareholder Roger Marshall made a personal representation to the MSQAC committee. He stated the release time posed no additional health risks, and this opportunity was too important for the industry to pass up, as there was no suggestion of disease risk the industry was in effect ‘shooting itself in the foot. 

·       
     The upshot was that the company gained a majority decision for the early release and it was then up to the Chief Veterinary Officer Dr Peter O’Hara to come to a decision and present this to the Minister of Agriculture (the late John Falloon).

·      This was done and the company squeaked through, even though Jock’s previous meeting with the Minister had elicited the opinion that he didn’t think it was all that important. Significantly, Federated Farmers' Meat and Wool Chairman Eddie Orr was strongly opposed to the three-week earlier release, clearly against the interests of his sheep farming members.

The semen freezing fiasco
·      From December 1995 to February 1996 the company froze 40,000 straws of semen from 20 rams to be ready for industry demand. In 1996 about twice as many sheep were artificially inseminated than have ever been in the sheep industry before or since. About 50,000 ewes were inseminated, 28,000 with frozen semen, the rest with fresh from rams the company had sold. 

·      The company specified that there should be a minimum of 15 million live sperm per straw, and early in the use of all this semen it was learned that some of the straws were ‘a bit thin’.  

·      Independent measurements showed that the average number of live sperm was about half of that specified, which created a big dispute with the contractor who maintained that they were world experts, and there was nothing wrong with their product. However, many farmers who got poor insemination results blamed the lower number of sperm per straw which was very hard to argue with. Most operators did very well with the straws but there were a lot of arguments. 

·      Fortunately the company had supplied semen for a very large field trial run by Dr John Smith at Ruakura, where straws of semen from the same ejaculate were used at various locations throughout the country. It was hard for the inseminators to blame the semen for 30 to 40% conception rates, when others in other locations were getting 60 to 80% with the identical product. 

·      However it still cost the company in excess of $100,000 to clear up all the disputes, which supported their refusal to pay for the freezing of the semen. They agreed to an independent arbitrator to assess the semen quality, and the result was as the company expected, that the average number of sperm per straw wasn’t much more than half of the specification.

Release from Quarantine  
·      The animals were released by the company around 20th March 1996 with a major auction at Regines nightclub at the Shoreline hotel in Dunedin. This had both TV channels and ‘Rams at Regines’ was the cry. The company sold some 28,000 straws of semen and 50 rams in 1996, and had ram auctions for the next three years at Gore, and sold many rams and pregnant ewes with East Friesian lambs in utero in subsequent years. 

·      There was an estimated 50,000 ewes of various breeds being artificially inseminated.

·      The company was not allowed to sell during the usual ram sale times at Gore, but in an evening auction in the town they sold 20 rams for a total value for more than all of the Romneys sold the next day. The pressure on the other breeders was on. 

·      In 1995 'Silverstream East Friesians' registered the first flock with the New Zealand Sheep Breeders’ Association (NZSBA), and in 1996 several more flocks were registered and this has continued, but only in small flocks.
