摘　　要：对西藏农区的母黄牛、黑白花母牛、西门塔尔母牛、茨盖羊、藏系母绵羊和藏系公绵羊进行体尺测定,以年龄为自变量,体重为因变量进行曲线拟合。拟合曲线的相关系数分别为0.83,0.72,0.78,0.68,0.67和0.74。对实测值和估测值之间进行F显著性检验,均差异不显著(P>0.05),回归模型能够真实地反映西藏农区家畜的生长特点。The age as independent variable and body weight as dependent variable was realized curve fitting to Body measurements of Bostaurusdomestica cow, Holstein cow, Simmental cow, Tsigai, the ram and ewe of Tibetan sheep in Tibet agriculture region. The correlation coefficients of curve fitting are 0. 83,0. 72,0. 78,0.68,0. 67 and 0. 74, respectively. The between measured values and estimated were no significant（P〉0.05）. The growth characteristics of cows and sheep in Tibet agriculture regions were truly realized in these regression models.
