The Jacob Sheep Breeders Association
(JSBA) took over the work begun by the American Minor Breeds Conservancy
, now know as the The Livestock Conservancy. The AMBC began identifying Jacob Sheep in North
America in 1985. By 1988, the AMBC assisted the JSBA in forming a breed
association and registry from a core group of breeders interested in the
continuance and conservation of the breed. The first JSBA flock book was
published the following year with over 400 animals inspected and registered.
By 2006, over 10,000 Jacob Sheep had been registered by JSBA. Despite a
steady increase in numbers, the American Jacob is still listed as a rare
breed by the The Livestock Conservancy.
