德系西门塔尔与荷斯坦杂交一代犊牛生长规律的研究

摘要

为了研究德系西门塔尔与荷斯坦牛杂交产生的1代乳肉兼用犊牛的生长规律,测定了50头F1代犊牛从初生到6月龄的体重、体高、体斜长、胸围和管围.结果表明,西×荷F1犊牛生长速度要快于本地荷斯坦犊牛,能够更早地达到配种体重;在6月龄时体重、体高、胸围、体斜长和管围分别为210.4kg、103cm、134.5cm、198.58cm、15.67cm.可以得出,西×荷杂交产生的乳肉兼用牛在河北地区的生态气候条件下,其生长发育良好,适合在河北省养殖.%To study on the growth rule of Simmental Dual-purpose calf in Hebei province, the objective of this study was to measure the body weight,height,length,chest and pipe circumference of 50 Simmental dual-purpose calfs from born to 6-month age,aiming to reveal the growth and development pattern. The result showed that the growth of Simmental Dual-purpose calfs was faster than Holstein calfs, they could reach breeding weight much eailer. The body weight,height,chest,length and circumference of Simmental Dual-purpose calf at 6-month age respectively were 210.4kg,103cm,134.5cm,198.58cm and 15.67cm. The Simmental Dual-purpose calfs are suitable for farming in Hebei province, because they can adapt to the ecological condition very well.
