摘　　要：南阳牛以体格大、役肉兼用、耐粗饲、适应性强而著称,夏南牛和“皮南牛”是以南阳牛为基础育成的肉牛品种,本文采用模型化方法对其体重生长发育及早熟性进行了研究。结果显示,夏南牛和“皮南牛”具有生长发育早熟性较好,生长强度大的特点,断奶重相对较大,12月龄体重分别相当于其36月龄体重的56.60%和62.21%。其中,“皮南牛”在周岁以前生长强度更大。Nanyang cattle is famous for its large body size,dual purpose for meat and draft,roughage-tolerance and strong adaptability.Xianan and Pinan cattle are beef cattle breeds bred basing on Nanyang cattle.The weight growth and early maturity of the breeds were studied by using of model-based approach in this paper.The results showed that Xianan and Pinan cattle have the characteristics of early maturity and strength growth,higher weaning weight,12-month-old body weight are of 56.60%and 62.21%of that in 36-month-old for Xianan and Pinan cattle respectively.Among them,"Pinan cattle"grow stronger before one year old.
