澳湖杂交F_(1)代生长性能试验研究

Study on Growth Performance of F_(1) Generation of Crossbreeding of Australian White Sheep and Hu Sheep

为了研究澳洲白与湖羊的杂交效果,2023年5月以湖羊为母本、澳洲白为父本进行杂交试验研究,选择澳湖杂交F1以及湖羊纯繁一代的羔羊初生、2月龄、4月龄、6月龄进行体重、体长、体高测量。结果表明:(1)澳湖F1平均体重比湖羊纯繁一代分别提高13.06%、25.44%、24.83%和21.31%;(2)平均体长分别提高7.75%、7.61%、10.55%和11.86%;(3)平均体长分别提高5.9%、6.13%、8.05%和13.19%。研究认为,澳湖杂交代生长性能优于湖羊,优先选为嘉峪关市肉羊产业发展的杂交繁育组合。

In order to study the hybrid effects of Australian White sheep and Hu sheep,the growth performance test was conducted at Jiayuguan Shenghao Agricultural Science and Technology Development Co.,Ltd.sheep farm with Hu sheep as the maternal parent and Australian White as the paternal parent.Through the experiment,the growth performance of Australian White×Hu sheep F_1 generation and pure-bred generation of Hu sheep was studied,and the optimal combination suitable for the high-quality development of Jiayuguan's sheep industry was selected.
