Abstract:The development of sheep breeding in alpine pastoral areas is largely influenced by geographical environment and feeding and management conditions. This leads to slow growth and development of sheep, low production performance, low slaughter rate, and low economic benefits. In order to explore and solve this problem, we make full use of the economic advantages of black fur Tibetan sheep to crossbreed with local Tibetan sheep. We carried out highefficiency breeding and advanced technology promotion and application of its offspring, which made the hybrid offspring of black fur Tibetan sheep become an excellent breed with large body, high limbs, strong disease resistance, fast growth, and high survival rate in alpine pastoral areas. The results show that the black fur Tibetan sheep after hybridization has good stress resistance and adaptability to the ecological environment of the alpine pastoral area, and has fast growth and high slaughter rate. On the 60th, the daily gain of growth and development of the lambs reached 191.17 g, compared with 89.67 g in the control group, and the wool yield, carcass weight, and net meat volume increased significantly (P< 0.05). This effect is very remarkable, and is favored by the local farmers and herdsmen.
