摘要: 通过测定150头育成牛从出生到配种前各月龄牛的体重、体高、体斜长、胸围和管围,掌握其生长发育规律,绘制生长发育曲线。结果表明,育成牛在13月龄时体重、体高、胸围、体斜长和管围分别为366.26 kg、125.69 cm、168.01 cm、139.38 cm和17.83 cm,均达到了配种要求;在8月龄之前各项体尺增长最快,8月龄之后速度减慢。犊牛和育成牛体重的评估模型为:Y=-284.087+4.747X1+5.664X2-3.209X3-25.352X4或Y=96.475X22X3

Abstract: The objective of this study was to measure the body weight,height,length,chest and pipe circumference of 150 Chinese Holstein calf and heifers from born to breeding,aiming to revealing the growth and development pattern and drawing the growth curve. The results showed that the body weight,height,length,chest and pipe circumference of heifers at 13-month age respectively were 366.26 kg,125.69 cm,168.01 cm,139.38 cm and 17.83 cm,reached the breeding requirements. The fastest growth period of heifers was from birth to 8 month old,the speeding of growth decreased after 8 month old. The estimate of body weight for calf and heifer were:Y=-284.087+4.747X1+5.664X2-3.209X3-25.352X4 and Y=96.475X22X3.
