Rare Breeds Survival Trust Rare Breeds Survival Trust The Rare Breeds Survival Trust is a conservation charity whose purpose is to secure the continued existence and viability of the native farm animal genetic resources (FAnGR) of the United Kingdom. It was founded in 1973 by Joe Henson to preserve native breeds; since then, no UK-native breed has become extinct. It maintains a watch list of rare native breeds of cattle, sheep, pigs, horses, goats and poultry, and an approved list of farm parks. Projects have included the collection of genetic material to ensure the future of rare breeds in a farm animal "gene bank".
Cryoconservation of animal genetic resources area, making the process of collecting germplasms easier and more efficient. The species and breeds of animals housed should be considered while planning the facility; facilities should be big enough to meet animal welfare standards, yet small enough to reduce human contact and increase ease of handling while reducing stress of the animal. As the process of collecting germplasm may take several days, the animal may become stressed causing a lower quality of genetic material to be obtained. Thus, training the animal to become familiar with the process is key. Holding facilities for animals may also serve as a quarantine.
