安徽白山羊经济杂交生产性能测定与杂交组合筛选
Economic cross performance test and cross combination screening on Anhui white goat
摘要
Abstract
In order to improve the mutton production and sheep economic benefits of Anhui province, the world famous sheep breeds-Boer goats and Saanen dairy goats were introduced, which crossbred with local Anhui white goats. The growth and reproductive performance of Anhui white goats, two-way crossbreeding (B×A and S×A), three-way (B×S×A) and grading crossbreeding (B×B×A and B×B×B×A) were studied. Compared with Anhui white goats, the daily gain of BxAF3(118.3 g), B×S×A(107.8 g), BxAF2(110.2 g), B×AF1(102.5 g), S×A (84.5 g) from 0 to 12 months increase by 95.9%, 78.5%, 82.5%, 69.7% and 39.9%, respectively; the lambing rate: Anhui white goats (236.0%) > B×AF1 (213.3%) > S×A (209.0%) > B×S×A (204.2%) > B×AF2 (198.6%) > BxAF3 (189.8%); the survival rate of 2-month-old weaned lambs: B×S×A (94.9%) > S×A (93.6%) > BxAF2 (93.1%) > B×AF3 (92.5%) > B×AF1 (92.3%) > Anhui white goats (90.7%). The test results reveal that B×S×Ahas the highest production efficiency, followed by BxAF2.关键词
