【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(P0.01);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 modern production of animal husbandry and guide the herdsmen to keep the herdsmen accurately and scientifically, the body mass and body size data of a herdsman, Sunita, from June 2015 to June 2016, in the Eastern Su Banner of Xilin Guolle League, were taken as the research objects. The changes of body mass in Sunita sheep were studied. Firstly, using the method of grey correlation analysis, the meteorological factors limiting daily gain of grazing sheep were studied, and the order of meteorological factors affecting daily gain of grazing sheep was obtained: temperature, wind speed, sunshine precipitation, visibility pressure and humidity. Secondly, the correlation analysis, path analysis and correlation coefficient decomposition of the body size of adult Sunita sheep were carried out by using SPSS 19.0 software. The results showed that there was a significant correlation between body weight and chest circumference (x 3), body length (x 2), chest depth (x 4), body height (x 1), body length (x 2) and chest circumference (x 3), which had direct and indirect effects on body mass. Body height (X 1) and chest depth (x 4) mainly assist other traits to influence body weight indirectly.
