摘要: 本研究利用SAS 8.1软件的最小二乘方差分析和MTDFREML软件对南山种羊场的2125只中国美利奴羊(新疆型)的初生重进行了遗传力估计,并分析了非遗传因素对羔羊初生重的影响。结果表明,初生重的遗传力为0.30,属于中等遗传力(0.1<h2<0.3)。在非遗传因素中,母亲年龄、出生年份、产羔类型和群别对羔羊的初生重有极显著影响(P<0.01),而性别对初生重无显著影响(P>0.05)。试验结果为中国美利奴羊(新疆型)进一步选育提供一定的依据。

Abstract: The article estimate the heritability and analysis the influence of non-genetic factors on birth weight of the number of 2125 Chinese Merino sheep (Xinjiang type) by using SAS 8.1 program of least-squares analysis and MTDFREML software, the data collected from Nanshan sheep breeding farm. The results showed that the birth weight heritability of Chinese Merino sheep was 0.30, it belonged to the moderate heritability (0.1<h2<0.3). The maternal age, year of birth, lambing type and group were highly significantly effect on birth weight (P<0.01), but the gender was no significantly effect on birth weight (P>0.05).
