摘要: 为了促进畜牧业现代化生产,指导牧民精准饲养、科学选育,以2015年6月至2016年6月的锡林郭勒盟东苏旗某牧户苏尼特放牧羊体质量、体尺数据为研究对象,对苏尼特羊体质量变化特征进行研究。首先采用灰色关联分析方法,对限制放牧羊日增重大小的气象因素进行研究,得到影响放牧羊日增重大小的气象因素排序:温度>风速>日照>降水>能见度>气压>湿度。其次采用SPSS 19.0软件对成年苏尼特羊的体质量体尺进行相关性分析、通径分析及相关系数分解,结果表明:体质量(y)与胸围(x3)、体长(x2)、胸深(x4)、体高(x1)呈极显著相关(P<0.01);体长(x2)和胸围(x3)指标对体质量(y)具有直接和间接影响,体高(x1)和胸深(x4)主要辅助其他性状指标间接影响体质量(y)。

Abstract: In order to promote the modernization of animal husbandry and guide herdsmen precision feeding and scientific breeding. the weight change features of the Sunite sheep were studied. The sheep’s body weight, body size data from June 2015 to June 2016 in a Xilinguole Meng East Su Qi herdsman farm were taken as the research object. Firstly, the method of gray correlation analysis was used to find meteorological factor limiting Sunite sheep’s daily weight gain. The rank of meteorological factors affecting the body weight of Sunite sheep was as temperature>wind speed>sunshine>precipitation>visibility>pressure>humidity. Secondly, the correlation analysis, path analysis and correlation coefficient decomposition of sheep’s body weight and size were carried out by SPSS 19.0 software. The results showed that body weight (y) and chest circumference(x3)、body length(x2)、chest depth (x4)、body height (x1) were significantly correlated (P<0.01). The body length (x2) and chest (x3) index had direct and indirect effects on weight (y). The height (x1) and chest depth (x4) were assisting other traits to influence body weight (y) indirectly.

Key words: Sunite sheep, grey relational analysis, body weight, body size, correlation analysis, path analysis
