摘要:

为了探讨云上黑山羊体重与成年性状间的相互关系,基于98只云上黑山羊母羊的体重记录和成年性状数据,利用R语言对体重和成年性状共11个变量进行简单相关分析和典型相关分析。简单相关分析结果表明,除18月龄校正体重和12月龄校正体重外,相邻体重之间极显著相关(0.30<r<0.42,P<0.01);18月龄校正体重与成年性状(除体高外)之间为极显著相关(0.39<r<0.76,P<0.01);胸围、管围、背膘厚和眼肌面积之间达到显著相关(0.24<r<0.76,P<0.05)。典型相关分析结果显示,体重与成年性状之间的相关性主要是由18月龄校正体重和胸围引起的。以上提示,胸围是影响云上黑山羊体重的主要成年性状,可作为重点选育指标。

Abstract:

To explore the relationship between body weight and adult traits of Yunshang black goat, based on the body weight and adult traits data of 98 Yunshang black female goats, Pearson correlation analysis and canonical correlation analysis were performed on 11 variables using R software. The results of Pearson correlation analysis showed that there was a highly significant correlation between adjacent body weight (0.30<r<0.42, P<0.01) except adjusted body weight at 12 and 18 months of age; there was a highly significant correlation between adjusted body weight at 18 months of age and adult traits except body height (0.39<r<0.76, P<0.01); chest girth, canal circumference, backfat thickness and eye muscle area were significantly correlated (0.24<r<0.76, P<0.05). Canonical correlation analysis showed that the correlation between body weight and adult traits was mainly contributed by adjusted body weight at 18 months of age and chest girth. The study indicates that chest girth could be selected as a promising breeding index which is a key adult trait affecting body weight of Yunshang black goat.
