摘　　要：三峡库区川南山地黄牛及其8种杂种后代的体重资料用Logistic和Gompertz模型进行生长曲线拟合分析。结果表明:2种模型都能很好地拟合川南山地黄牛及其8种杂种后代的生长发育规律,但Gompertz模型尤佳。成熟体重最大的是西杂牛313.2373 kg,最小的是本地黄牛166.1484 kg。引进的8个肉牛品种对本地黄牛都有改良效果,较好的有西门塔尔牛、海福特、红安格斯、德国黄牛、利木赞牛。The data of body weight of Chuannan mountainous cattle and eight kinds of hybrids were fitted with Logistic and Gompertz models.The results indicated that two models could be fitted very well for all cattles,and Gompertz model was better in fitting.The biggest mature weight was Simmental hybrid,313.2373 kg,while the smallest was local cattle,166.1484 kg.Eight kinds of introduced beef cattle had good effect on improvement of local cattle,and the better of them were Simmental,Hereford,Red Angus,Gelbvieh and Limousin.
