摘要
为了探索西门塔尔牛对凉山本地黄牛杂交改良效果,选择示范区测定了初生、6月龄和12月龄西本F1代的体重、体尺并与本地黄牛进行了比较,西本F1代牛的各项指标均比黄牛有明显的提高,并在全县29个乡得到了推广应用,经济效益显著。
To explore the improvement effect on cross experiment between Simentaer cattle and Native cattle, the body weight and body type are respectively determined in nascent cattle, 6 months age＇ s cattle and 12 months age＇ s cattle of Xiben F1 generation in selective demonstration area. These data are apparently higher than that of native cattle. This hybridization technique has been introduced in 29 towns and brings notable economic benefit.
