The development of farm animals since the beginning of domestication is described. Modern breeds have existed since the end of the 18th century. Different efficiency with regard to what were topical breeding aims as well as manipulations by the government led to a decrease in the variety of breeds. The reasons of preserving endangered breeds are both genetic and cultural. There are some examples of breeds that once had little attention payed to and which now have obtained economic importance again. In recent years several institutions in West Germany have tried by financial advancement and other measures for a variety of breeds to avoid further curtailment of them.
本文描述了自驯化开始以来农场动物的发展历程。现代品种自18世纪末就已存在。由于当时的育种目标不同以及政府的干预，导致品种多样性有所减少。保护濒危品种的原因既有遗传方面的，也有文化方面的。有些品种曾经不受关注，现在却再次具有了经济重要性。近年来，西德的一些机构通过资金支持和其他措施来保护各种品种，以避免其进一步减少。
