摘　　要：为了挖掘高寒牧区放牧藏羊繁殖潜能,提高繁殖效率,进行了藏羊早期配种试验研究,结果表明藏羊通过早期培育,在10~13月龄配种,产羔率达到99%,羔羊发育和生长良好,母羊连续繁殖第二胎产羔率98%,两胎羔羊成活率均在97%,母羊体重高于常规放牧饲养的同龄母羊,没有发现对母羊健康和连续繁殖能力造成的影响,具有示范推广意义。In this paper, the early breeding experiment of grazing Tibetan sheep in Alpine pasture was conducted to tap their breeding potential and improve their reproductive efficiency. The results showed that the lambing rate of sheep reach 99% by the early cultivation, which was bred at the age of 10-13 months and Lambs develop and grow well. The lambing rate of second birth reach 98%.The survival rate of two fetal lambs is 97%. The body weight of experimental ewe is higher than that of conventional grazing ewe. The health and continuous reproductive ability of ewe has not been influenced. This test has the significance of demonstration and promotion.
