不同生态区藏山羊的产绒性能研究

选择青藏高原四个不同的生态区，对藏山羊的产绒性能进行了研究，结果表明：西藏两个产区藏山羊的产绒量和绒的主要品质指标均高于四川两个产区，尤其是西藏阿里地区藏山羊的产绒量和绒的品质明显优于其他产区，四川茂县藏山羊的产绒量和绒的品质较差；同时，西藏两产区藏山羊的产绒量从年龄上看以４岁较高，从毛色上看以白色个体较高；四个不同生态区内藏山羊的产绒性能差异较大，越严酷的高寒生态条件，其产绒量越高，绒的品质越好。今后应根据不同的生态区按不同的生产方向对藏山羊这一宝贵的基因库资源进行开发利用。

Studies on Down Producing Performances of Tibetan Goat Breed in Diversitied Ecological Areas

The variant performances pertaining to down hair in Tibetan goat breed in four different ecological areas on Qinghai-Tibet Plateau had been studied.The results showed that all targets of down-bearing wool hair yield and main Cashmere wool fiber qualities of goats in two Tibetan areas were clearly higher than those in two areas of Sichuan Province,and especially,thoses targets were exceedingly better in Tibetan Ali District and relatively poor in Mao County of Sichuan Province.According to the ages of goat and wool colors in goat bodies were ranked to the highest grade in individual down-bearing wool yields in goats at the ages of four years old and white colored animals which were raised in two Tibetan areas.The differences of down-bearing wool producing performances of goats in those four said areas were quite clear,the higher the elevation level and the colder the climate.Of course,the higher the down-bearing wool yields,and the better the wool fiber quality.It is now suggested that we should develop and utilize this valuable genetic pool resources of the Tibetan goat breeds from many different producing regions(including neighboring provinces as according to those different ecological areas in the future).
