摘要
通过对延边黄牛和韩延F1牛体重和体尺的对比,分析其生长发育规律,结果表明,韩延F1牛各月龄体重均高于延边黄牛;延边黄牛公、母牛体长的生长发育速度在8月龄左右快于体高,而韩延F1公、母牛的体长的生长发育在4月龄左右就已经快于体高;韩延F1公牛坐骨宽的发育也早于延边黄牛公牛,按性别来说,6月龄前母牛的后躯宽度（腰角宽、坐骨宽）生长强度较公牛大,6～18月龄公牛逐渐超过母牛.
According to compare the weight and body size, the growth regularity of Yanbian Yellow Cattle and Hanyan F1 Cattle was analysised. The results showed： the body weight in each month of Hanyan F1 Cattle was all higher than Yanbian Yellow Cattle, the growing speed of body length was faster than body height in Yanbian Yellow Cattle, at the 8th month which was at the 4th month in Hanyan F1 Cattle. The growth period of sciatic width of Hanyan F1 Cattle was earlier than Yanbian Yellow Cattle. The cow＇s hipbone width and sicatic width growth intensity was faster than the young bull＇s before 6 month, but the growth intensity of young bull was fast after 6 month.
