摘 要: 测定了中国西门塔尔牛杂交F1代与当地黄牛的生长发育情况,在同等饲养管理条件下,中西杂F1牛初生、3月龄、6月龄、12月龄以及18月龄各年龄段指标比同期本地黄牛都有不同程度的增加与改变。以周岁牛为例,中西杂F1代比当地黄牛体高、体长、胸围、体重分别提高11%,7%,15%,57%,差异显著,且改良后代表现出疾病少,耐粗饲,适宜脑山地区农村放牧条件的特性。 The growth and development of Chinese Simmental crossbreed F1 and local cattle were determined. Un-der the same management conditions, the indexes of Chinese Simmental with aged with birth, 3 , 6 , 12 and 18 month were higher than that of local cattle in the same period. Take the one - year - old cattle as an example, the body height, body length, chest circumference, weight of Simmental crossbreed F1 increased by11 % ,7 % , 1 5 % ,57% respectively compared with local cattle. There is significant difference between them, and the improved offspring showed less disease, rough feeding, suitable for the rural grazing conditions.
