摘要
本文在引入澳洲美利奴公羊对高山美利奴羊进行选育提高的进程中,通过对生产出含澳血的F1代周岁母羊与纯种高山美利奴周岁母羊在体重、剪毛量、羊毛纤维直径、体侧毛长、净毛率等生产性能方面的数据进行测定采集后,经过对测定的数据进行统计分析对比,得出改良效果为含澳血F1代周岁母羊比纯种高山美利奴周岁母羊在体重、剪毛量、体侧毛长和净毛率等生产性状方面选育提高差异极显著,应进一步扩大选育提高改良规模,生产出优质种羊,通过国家绒毛用羊技术体系平台向社会推广,在助推乡村振兴,促进广大牧民和养殖户致富增收方面发挥积极作用。
In this paper, in the process of introducing Australian Merino rams to improve the alpine Merino sheep, through the production of F1 year-old ewes with Australian Merino lineage and purebred Alpine Merino year-old ewes Data on production performance such as body weight, shearing amount, wool fiber diameter, body side hair length, and net wool rate are measured and collected. After statistical analysis and comparison of the measured data, we have concluded that the improvement effect is that the F1 generation yearling ewes with Australian Merino blood are better than the purebred Alpine Merino yearling ewes in terms of body weight, shearing amount, side hair length and net weight. The difference in breeding improvement in production traits such as gross rate was extremely significant. We should further expand the scale of breeding and improvement, produce high-quality breeding sheep, and promote them to the society through the platform of the national wool sheep technology system platform, so as to play an active role in boosting rural revitalization and promoting the wealth and income of herdsmen and farmers.
