摘　　要：为了研究本地西杂牛与德系西门塔尔牛杂交的F1代、F2代公牛生长规律,选择健康的本地西杂母牛100头,用德系西门塔尔牛冻精对其及F1代进行人工授精,测定F1代、F2代公牛从初生到24月龄的体重、体高、体斜长、胸围和管围等,掌握其生长发育规律。结果表明,在0~6月龄阶段,F2代公牛的生长速度快于F1代公牛;在6~24月龄阶段,F1代、F2代公牛体重、体尺指标基本相同,但与西门塔尔公牛相比有很大差距,还存在较大的生长潜力。试验表明,F1代、F2代公牛均能够适应河北省地区的生态气候条件,如加强饲养管理使其充分发挥杂种优势,将会进一步提高养殖户的经济效益。To study the growth rule of hybrid F1 and F2 generation bulls by local hybridized and German Simmental cattle,a total of 100 healthy local hybridized cattle were randomly divided into two groups,they and their hybrid F1 generation were artificial inseminated by simmental frozen semans,and were to measure the body weight,height,length,chest and pipe circumference of hybrid F1 and F2 Generation Bulls.The result showed that the growth rate of hybrid F2 generation was faster than hybrid F1 generation bulls in the stage of 0~6 months old.The weight and body size indexes of hybrid F1 and F2 generation bulls were basically the same in the stage of 6~24 months old,but there was a big gap between them and simmental bulls and was still a large growth potential.The hybrid F1 and F2 generation bulls are suitable for farming in Hebei province,so the breeding management should be strengthened to make them give full play to their hybrid advantages and at last to improve the economic benefits of farmers.
