摘要：
The conservation of endangered breeds as live animals is at present the main national strategy of the government and breeding organizations to maintain genetic diversity. Fourty-three breeds and some old strains of cattle, pig, sheep, goat and horses are currently involved. Cryopreservation and banks for sperm, embryos or DNA are another type of genetic material which could subsequently be used for breeding and production in agriculture. Present semenbanks involve 9 endangered cattle breeds and also a small amount of deepfrozen sperm of some endangered sheep and horse breeds. Only 2 embryobanks are established in government projects for cattle breeds Mumau-Werdenfelser and the old type German black-white cattle.
