摘要:

【目的】研究哈萨克羊的体重和体高、体斜长等体尺性状间的生长发育规律,为哈萨克羊的选育提供参考。【方法】收集1 091只12月龄以上哈萨克母羊生产性能鉴定记录,共包含体重和8个体尺性状,并对各性状进行统计分析。【结果】哈萨克羊的体尺性状的整体变异系数处于正常水平,其中尾宽和尾长的变异系数最大,分别达到了17.42%和16.9%。体重与体斜长、胸围等具有极显著相关性(P<0.01),与尾宽、尾长具有极显著负相关性(P<0.01);从9个主成分中提取3个分别反映哈萨克羊的体重体长信息、躯体宽度信息、管围信息以及体高信息的代表性主成分。用主成分提取因子拟合回归方程比直接利用体尺性状拟合准确度更高。【结论】用主成分提取因子可以更好的解析哈萨克羊体重与各性状之间的内在联系,简化部分工作量。

Abstract:

【Objective】 To study the growth and development of body size traits such as body weight, body height, and body length in Kazakh sheep, Simplify part of the workload and provide a reference for Kazakh sheep breeding. 【Methods】 In the experiment, a total of 1091 Kazakh ewes over 12 months of age, including body weight and 8 individual ruler traits were collected, and statistical analysis of each trait was conducted. 【Results】 The coefficient of variation of body size traits of Kazakh sheep was at the normal level, and the coefficient of variation of tail width and tail length was the largest, reaching 17.42% and 16.9% respectively. Body weight was significantly correlated with body length and chest circumference (P<0.01), and negatively correlated with tail width and tail length (P<0.01). 3 representative principal components were extracted from 9 principal components, which reflected body weight, body length, body width, girth and body height of Kazakh sheep respectively. We found that fitting the regression equation with the principal component extraction factor was more accurate than directly using body size traits. 【Conclusion】 Principal component extraction factor can better analyze the internal relationship between body weight and traits of Kazakh sheep.
