摘　　要：根据呼图壁牧三场2011~2015年1~6月龄新疆地区西门塔尔犊牛体尺和体重数据,研究新疆地区西门塔尔犊牛的生长规律,分析其体重与体尺指标的相关性,构建估测新疆地区西门塔尔犊牛体重的回归模型。结果表明:新疆地区西门塔尔犊牛随着月龄的增加,相对于其他几个性状,更趋向于胸围和体重的快速增长;体重与体高、体长、胸围、腿围、管围的相关系数分别为0.924、0.759、0.945、0.853、0.763,经检验四个相关系数均达到极显著水平(P<0.01);得到了2个估测体重的回归方程,对于公犊,Y=-323.10+1.40 X1+0.83 X2+1.45 X3-0.06 X4+7.02 X5,估测值与实测值之间的相关程度分别为0.953和0.949;对于母犊,Y=-282.70+1.29 X1+0.03 X2+1.89 X3+0.14 X4+5.69 X5,估测值与实测值之间的相关程度为0.957和0.955,均达到极显著水平(P<0.01)。Body measurement and body weight data of Simmental claves at 1 to 6 months old were collected from Hutubi No.3 Farm from 2011 to 2015 to study the growing Simmental calves in Xinjiang Area,correlations of body weight with body size were analyzed to construct the regression model for the body weight of Simmental calves in Xinjiang area.The results showed that the chest circumference and body weight of Simmental calves in Xinjiang area increased rapidly with the age in comparison with other traits;the correlation coefficients of body weight with body height,body length,chest circumference,leg circumference,cannon circumference were respectively 0.924,0.759,0.945,0.853 and 0.763,all reached extremely significant level(P<0.01);The regression equations of two estimated body weights were obtained,for male calves Y=-323.10+1.40X 1+0.83X 2+1.45X 3-0.06X 4+7.02X 5,the correlation coefficients of estimated values and measured valued were 0.953 and 0.949;for female calves,Y=-282.70+1.29X 1+0.03X 2+1.89X 3+0.14 X 4+5.69X 5,the correlation between the estimated values and measured values were 0.957 and 0.955,both reached extremely significant level(P<0.01).
