Herdwick Health
Herdwick sheep have a naturally high health status. This is borne out
by the fact that many ewes live and breed to a very advanced age. When
selecting rams for Association registration, considerable attention is
paid to good mouths as well as the breed points.
Tups are not just selected from small elite stocks but are also drawn
from the fell-going flocks of long-standing and vigorous
commercial flocks. This allows for a considerable and beneficial genetic
diversity constantly
to influence the breed.
Although the breed has not been
significantly troubled with scrapie (indeed many breeders
have not experienced a case), the Herdwick Sheep Breeders’ Association
in 1998 began a voluntary programme of scrapie resistance
testing using the genotype testing techniques developed
by the Central Veterinary Laboratory
and the Scottish Agricultural Colleges. Tups which had any
significant potential to transmit a susceptibility to
scrapie to their offspring were
required to be culled. Since the development pf the National
Scrapie plan the majority of members now test their rams
either through the NSP or privately.
