The National Dexter Beef Network
The beef meeting on 6th of February was a major step forward for our breed and our Society: Attended by almost 90 beef producers from all over the UK the audience consisted of a good cross section from the occasional beef producer to the large volume Dexter beef providers running farm shops and farmers markets.

Beryl Rutherford - Woodmagic
It is with great sadness that I have to record the death of member of council, Beryl Rutherford. To those who knew her, she was a great fund of knowledge and a true enthusiast for the breed. Always ready to share her knowledge, she was advising new breeders to the end. A pioneer with her work on the bulldog gene, long before the availability of a genetic test, the Woodmagic prefix is well respected worldwide.
Beryl's final resting place
is Great Bradley Cottage, Natural
Burial Ground, Calverleigh Cross, Templeton, Tiverton, Devon, EX16
8BJ.
Please
send donations to the Beryl Rutherford Memorial Fund, c/o

Memorial Fund.
We will be planting a tree on her grave on 13th June, 2010, all are welcome to join us.
Very sadly Michelle Amil Stamp passed away on Saturday, 22nd May, after a long illness.
Best wishes go to Bernard and family at such a sad time

Bluetongue Update - Feb 2009
Don’t hesitate, vaccinate . . .
The risk of bluetongue in 2009 remains serious. Defra will continue to promote voluntary vaccination against Bluetongue serotype 8 (BTV 8, there is a supply of 12 million doses of existing vaccine which Defra will make available for use, subject to expiry dates. Defra will not be underwriting further supplies of vaccine in 2009 but livestock keepers can purchase any of the three authorised BTV8 vaccines from Intervet, Merial or Fort Dodge. This flexibility provides farmers with a choice as to the best purchase options for their stock.
As at 10:00 on 2 February 2009 there were 149 confirmed premises affected by Bluetongue (BTV8) in England and Wales
All livestock farmers are strongly encouraged to be vigilant and to vaccinate at the earliest possible opportunity.
Farmers and veterinary professionals are reminded that Bluetongue vaccines should not be used beyond their expiry date.
Intervet have worked with Defra and the Veterinary Medicines Directorate to investigate the possibility of extending the expiry dates on some of the early expiring stocks of vaccine. However, the medicines legislation does not allow for the extensions of shelf lives for products after they have entered the supply chain. This means that extensions are not possible. Livestock keepers should therefore continue to abide by the expiry dates given on the vaccine packaging.
Livestock keepers are reminded that the risk of infection significantly rises with warmer weather, so vaccinating at the earliest opportunity, before the risk of Bluetongue spread increases is paramount. Farmers wishing to order vaccine should speak to their vet as soon as possible.
Details of available vaccines, including usage and cost are given on the Defra website here
For further information please check with the DEFRA website
The whole of Scotland became a Protection Zone on 3 November, 2008, vaccination in Scotland is compulsory.
For more details see the Scottish Executive website.

The BTV6 zone in the Netherlands and Germany was lifted as of 5 March. Both countries have presented sound evidence to the Commission suggesting that no virulent BTV6 virus strain has circulated in the Netherlands or Germany, and positive findings are most likely to be ascribed to the use of a modified live vaccine. No bluetongue clinical disease has been observed in the field or under experimental conditions.
The BTV11 temporary control zone in Belgium was also lifted as of 5 March. They have reported a similar situation to that of the Dutch and Germans, their investigations have ascribed the incident to the use of a modified live vaccine. The epidemiological situation has been assessed and no virus has been isolated and no clinical signs of bluetongue disease have been observed.
The UK is satisfied by the evidence given that this presents no additional risk to the UK. Strengthened surveillance will continue in these countries and control measures may be applied if there is evidence of circulation in 2009 or if a virulent strain is detected. We continue to manage any threat to the UK through conducting post-import tests on all imported animals for all BT serotypes. This means we can detect all types of Bluetongue through our routine testing.
The SCoFCAH statement and supporting evidence is now available on the Commission website:
http://ec.europa.eu/food/animal/diseases/controlmeasures/bluetongue_en.htm
In addition, Spain have also officially declared freedom from BTV4. After carrying out extensive surveillance no new cases have been found for just over 2 years. Full presentation is available on the SCoFCAH website
http://ec.europa.eu/food/committees/regulatory/scfcah/animal_health/presentations/bt_34032009_es.pdf
The zone map of Europe has now been updated to reflect these changes

Livestock owners are encouraged to remain vigilant for signs of disease, and to consider the risks and check the health and vaccination status of animals when sourcing any animals, from within the UK or abroad.
Genetics Project - Progress Report
Veronica Schofield
Yvonne Froehlich and I attended the presentation given to the RBST Conservation Committee by Prof.Mike Bruford on 11th January at Stoneleigh
The presentation summarised the first two years work. Five groups of Dexters, based on pedigree information have been sampled:
Dexter Old
Dexter General
Dexter Woodmagic
Dexter Aberdeen Angus introgressed
Dexter Mixed Introgression
The DNA profiling identifies three main population groups, one of which is the Woodmagic herd. The other two groups are made up of a mixture of the other four pedigree groups. In work using three different methods to analyse suspected admixture of other breeds, the “Old Dexter” animals are looked at as a potential “parent” of the main Dexter population, along with Kerry, Aberdeen Angus and Red Poll. All three methods showed the Old Dexter group to be by far the greatest contributor to the main Dexter population.
This confirms the fact that the Dexter is very definitely a distinct breed, with no significant influence from any of the other breeds used in the project so far. However the work is currently being expanded to include Devon, American Milking Devon, Welsh Black, Shorthorn, mainland Jersey and Guernsey, together with some more Dexter samples including some from some old American lines.
The project has also established that there is a high level of genetic variation within the breed in comparison with levels of variability within other British and European breeds. There could be a number of reasons for this – the fact that the Dexter is still a dual-purpose breed, with a range of conformation types could be significant. This is a healthy situation and reduces the risks of problems from inbreeding. Even the Woodmagic herd, which as a closed herd has less variation than the population as a whole, does not display a particularly high coefficient of inbreeding
Work is also being carried out on the origin of the dun coat colour. This particular mutation has not been found in any other breed to date.
Future work could involve tying up the allelic frequencies found in the breed with physical traits – colour and conformation for example.
Benefits of the Project
· registrations queries (eg herds believed to be pure but whose registrations have lapsed)
· promoting Dexter beef as a distinct brand,
· investigation of animals which do not conform to the breed standard (establishing if they are Dexter mutations or if another breed is involved).
· Prevention of future accidental introgression from other breeds
· There may be some future benefit in having a genetic template for the breed as far as the new government initiative on conserving traditional breeds is concerned
The 23 microsatellite markers being used in the project include 15 out of the 16 markers used for the Society’s DNA profiles. It would help to expand the pool of samples and provide a wider analysis of the breed, if some of the profiles could be used for the work at Cardiff. Council have agreed this in principal, providing permission is obtained from the owners of the animals concerned.
Any breeders who have had animals DNA’d and would be happy for the profiles to be used as part of the project, please contact Yvonne at the office, or, if you would like to discuss this further please give me a ring on 016974 73426 (evenings or weekends) or e-mail me on vschofield@btinternet.com
