波尔山羊×宜昌白山羊F_1代杂种羊生产性能的测定

目的]提高宜昌白山羊的生产性能。方法]通过人工授精,利用波尔山羊精液对宜昌白山羊进行改良,研究F1代杂交山羊的生长性能、屠宰性能和板皮性能。结果]在相同的饲养管理条件下,F1杂种山羊初生重,2、4、8、12月龄体重均明显高于宜昌白山羊,差异极显著(P<0.01)。F1代杂种山羊2、4、8、12月龄体长分别比宜昌白山羊提高32.46%、30.00%、32.05%和26.57%,胸围分别提高26.41%、23.68%、29.39%和19.73%。12月龄F1代杂种山羊的平均胴体重比宜昌白山羊高7.52 kg,屠宰率(47.26%)比宜昌白山羊高6.67个百分点。F1代杂种山羊鲜皮重、板皮面积均比宜昌白山羊显著提高。结论]利用波尔山羊杂交改良宜昌白山羊的生产性能是可行的,值得推广。

Determination of the Production Performance of F1 Hybrid Goat of Boer Goat and Yichang White Goat

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(P<0.01).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.
