The National Scrapie Plan (NSP) for Great Britain.
We are members of the National Scrapie Plan (NSP) for Great Britain. The aim is to reduce and eventually eliminate Scrapie from the national sheep flock.
Scrapie is a brain disease of sheep and goats. It has been present in this country (and many others) for well over 200 years. There are many clinical signs and most affected animals show some of these, many months or years after the animal has become infected. Most cases of Scrapie occur in sheep between the ages of two and five years.
With the Genotyping Scheme for purebred registered flocks it is possible to identify whether sheep are resistant or susceptible to Scrapie, by testing blood, semen or tissue.
The table shows 15 genotypes known to occur in sheep and their resistance or susceptibility to Scrapie.
A National Scrapie Plan Certificate will be issued for each male sheep that carries a Scrapie resistant genotype.
Certificates for male sheep that do not have the Scrapie resistant genotypes will indicate a date after which the animal cannot be sold or used for further breeding.
Certificates for ewes will only issued if they carry the ARR gene (but not the ARR/VRQ (R4) genotype).
It is recognised that it will take time to change the genetic make-up of the national flock. To this end, the National Scrapie Plan will initially concentrate on promoting the use of the ARR gene and excluding the VRQ gene (which scientific research indicates is the most susceptible to Scrapie) and allow the continued use of sheep with the ARH, ARQ and AHQ genes for a limited period (See above table)
Currently available science indicates that, as a result of the National Scrapie Plan, we should see a reduction of Scrapie and eventually its disappearance from the national flock.
We have only used ARR/ARR (R1) genotype Texel Rams in our Pedigree Flock of Texel sheep (Jonsland Flock) for the 2002 breeding year.

DEFRA has responded positively by announcing this consultation regarding R3 group Rams.
The Consultation proposes that the timescale for
selling and purchasing rams with genotypes AHQ/AHQ, ARH/ARH and AHQ/ARH be
extended from December 2004 to 2006 thus allowing another 23% of the Breed to be
