不同生态区藏山羊遗传资源的保存与利用

对青藏高原不同生态区的高原型藏山羊和山谷型藏山羊，应根据分布地区的生态条件和遗传资源特点，分别进行本品种选育和应用绒用、毛用、肉用及乳用品种进行改良，以保存其适应当地生态条件的基因，提高其生产性能，分别向绒用、毛用、肉用和乳用方向发展．高原型藏山羊，在海拨４０００ｍ左右的高寒地区，开展本品种选育，向绒肉兼用方向发展；由高原地貌向山谷型地貌过渡地带（海拔３０００ｍ）的地区，应用绒山羊品种改良提高产绒性能．山谷型藏山羊，在海拔２０００～３０００ｍ温暖干旱地区，应用绒用山羊改良，生产山羊绒，在海拔２０００ｍ以下温暖干旱地区，应用安哥拉山羊杂交改良山谷型藏山羊生产马海毛；在温暖湿润地区，应用肉用、乳用山羊品种改良，生产山羊肉和山羊奶

Conservation and Utilization of Tibetan Goat Genetic Resources in Different Ecological Zoons

The breed improvement of tibetan goats both of plateau type and Valley type which scatter in different ecological zoons are discussed.It is suggested that the animal should be improved by crossbreeding with the goat breeds of hair,down,meat and milk according to their ecological conditions and characters of genetic resources.While genes for adaptability to local ecological conditions of Tibetan goats are protected,their down performance must be improved.The purpose of improvement is to increase hair,down,meat and milk production.
