摘要
通过对西安现代化农业开发公司草滩农场170头荷斯坦牛后备牛初生,4月龄至16月龄体高、体长、胸围及体重进行测定,统计各月龄体高、体长、胸围及体重的累积生长的平均值、绝对生长值、相对生长值,对应绘制出四项指标的累计生长、相对生长曲线;分析了西安地区中国荷斯坦牛的早期生长发育状况,为制定后备牛的培育方案奠定了基础。
This study based on the measurement records of the withers height, body length, chest girth from 170 reserve cows of Chinese dairy cattle in Dairy Cattle Farm of Caotan Farm from 1994 to 2007 in Xi＇an city. The withers height, body length, chest girth and body weight were measured and its accumulation growth, absolutely growth and relative growth were calculated. The normal growth curves of the accumulation growth, absolutely growth and relative growth for the withers height, body length, and chest girth and body weight were made. The normal growth rule of reserve cow of Chinese dairy cattle in Xi＇an area were analysis. Those research results provide foundation for making cultivation plan of reserve cow.
