摘要
为了解三个引进肉羊品种与阿勒泰羊的杂交F1羔羊生长发育性能,以43只特克塞尔与阿勒泰羊(TA)、25只萨福克与阿勒泰羊(SA)及22只道赛特与阿勒泰羊(DA)的杂交F1羔羊为研究对象,测定不同生长阶段的体重和体尺,比较不同杂交组合的生长发育指标。结果显示,不同杂交组合的4、6月龄平均日增重无差异,而TA组的初生重显著高于SA,且后躯肌肉明显优于另外两个品种杂交羔羊组。说明三种杂交组合中,以特克塞尔与阿勒泰羊的杂交羔羊组的体躯指标较佳。
Purpose: to study the growth and development indexes of F1 hybrid lambs derived from 3 introduced breeds crossing Aletai sheep. Methods: The traits of liveweight and body weight were measured and studied for 43 Texel and Aletai hybrid lambs (TA), 25 suffolk and Aletai hybrid lambs (SA), and 22 Doset and Aletai hybrid lambs (DA). Results: it was indicated that there was no difference in average daily gain of 4 and 6 months old for different F1 hybrid lambs, but the birth weight of TAF1 was significantly higher than that of SA,and the muscles of the hindquarters were significantly better than the other two crossbred lambs.Conclusion: the body index of hybrid lambs of Texel and Aletai was better than other hybridized combinations.
