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F_1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F_1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,103 cm,134.5cm,198.58 cm and 15.67 cm.The Simmental Dual-purpose calfs are suitable for farming in Hebei province,because they can adapt to the ecological condition very well.
