摘要/Abstract

摘要：

【目的】研究和田羊不同生长阶段体重、体高、体长、胸围、胸宽、胸深和管围等体尺指标之间的关联性,为后期和田羊的选育、鉴定提供方向和理论依据。【方法】利用SPSS 19.0进行描述性统计和聚类分析,采用SAS 8.1对初生、周岁、成年三个生长阶段和田羊体重、体高、体长、胸围、胸宽、胸深和管围7个体尺指标进行进行主成分分析。【结果】(1)各生长阶段和田羊的体重变异系数均最大,且体高的变异系数最小。(2)在聚类分析中,初生阶段和田羊各体尺指标中体重、管围、胸宽和胸深聚为一类,体高、胸围、体长聚为一类,周岁阶段和田羊各体尺指标中体高、体长、胸围聚为一类,胸深、胸宽、体重聚为一类,管围单聚为一类;成年阶段和田羊各体尺指标中体高、体长、体重聚为一类,胸深、胸宽、管围聚为一类,胸围单独聚为一类。(3)初生阶段仅有一个主成分,周岁和成年阶段和田羊各体尺指标分为四个主成分。【结论】在提高和田羊的经济性状时,各体尺指标中应以体重、胸围和管围为主,兼顾体高、体长、胸深、胸宽等指标,用相应的指标来判断其经济性状,从而提高和田羊的选种、选育速度。

Abstract:

【Objective】 This study is aimed at clarifying the correlation among body size indexes such as body weight, body height, body length, chest circumference, chest width, chest depth and tube circumference of Hotan sheep at different growth stages, in the hope of providing direction and theoretical basis for breeding selection and identification of the sheep in later stage.【Methods】 In this study, SPSS 19.0 was used for descriptive statistics and cluster analysis, and SAS 8.1 was used to carry out principal component analysis on seven body size indexes of body weight, body height, body length, chest circumference, chest width, chest depth and tube circumference of sheep at three growth stages of birth, first year and adult.【Results】 First, the coefficient of variation of body weight was the largest at all growth stages and the coefficient of variation of body height was the smallest.Second, in the cluster analysis, body weight, tube circumference, chest width and chest depth were grouped together in the newborn stage, body height, chest circumference and body oblique length were grouped together in the first year, body height, body oblique length and chest circumference were grouped together in the first year, chest depth, chest width and body weight were grouped together in the first year, and tube circumference was grouped together in the first year.In adult Hotan sheep, body height, body diagonal length and body weight were grouped into one category, chest depth, chest width and tube circumference were grouped into one category, and chest circumference alone was grouped into one category.There was only one principal component in the primary stage, and the body size indexes in the first year and adult stages were divided into four principal components.【Conclusion】 When improving the economic traits of Hotan sheep, the weight, chest circumference and tube circumference should be the main indicators in each body ruler, and the body height, chest depth and chest width should be taken into account, and the corresponding indicators should be used to judge the economic traits, so as to improve the seed selection and breeding speed of Hotan sheep.

Key words: Hotan sheep; different growth stages; body size weight; principal component analysis; clustering analysis
