The Kerry is the most numerous of the three surviving indigenous breeds of cattle in Ireland. With a total population currently under a thousand animals it is listed as endangered in the World Watch list. Conservation efforts currently focus on both in situ and ex situ conservation. This approach is possible because of the existence of a few enthusiastic pedigree breeders, a breed society and a herdbook with registrations dating back to the 19th century. The Kerry cattle population is small with overlapping generations. The main objective in its conservation is to minimise inbreeding and conserve genetic variation. The Irish Cattle Breeding Federation (ICBF) was recently mandated to support and co-ordinate the conservation efforts which are centred around minimum coancestry selection, a mating advisory service, semen and embryo cryoconservation. To this end, a mean relationship system was developed for the routine computation of inbreeding and provision of a mating advisory system. Four bulls are identified annually for semen collection and storage. A second scheme aims to identify 15 cows for embryo cryoconservation over a three-year period. Future conservation efforts will benefit from the collation of Kerry cattle breeding and production information in a central database. This and a study of the dynamics of the Kerry cattle population are future priorities for ICBF in an effort to prevent the extinction of the Kerry cattle.
