Abstract
[Objective] The aim of the research was to enhance the production performance of Yichang white goat.[Method] Through artificial insemination,Yichang white goat was improved by using the semen of Boer goat.The growth performance,slaughter performance and skin performance of F1 germination hybrid goat were studied.[Result] Under the same feeding and management conditions,the birth weight and the body weight of F1 germination hybrid goat on the 2nd,4th,8th and 12th month were obviously higher than that of Yichang white goat with extremely significant difference(P0.01).The body length of F1 germination hybrid goat on the 2nd,4th,8th and 12th month were increased by 32.46%,30.00%,32.05% and 26.57% resp.than that of Yichang white goat,and chest circumference were increased by 26.41%,23.68%,29.39% and 19.73% resp.The average carcass weight of F1 germination hybrid goat on the 12th month was 7.52 kg higher than Yichang white goat and its slaughter rate(47.26%) was 6.67% higher than Yichang white goat.Both the fresh peltry weight and skin area in F1 germination hybrid goat were significantly increased than that of Yichang white goat.[Conclusion] It was feasible to improve the production performance of Yichang white goat by crossbreeding Boer goat.
