新疆褐牛的体尺、体重对产奶量的影响

Effect of Body measurement and Body Weight on Milk Production of Xinjiang Brown Cattle

本试验在新疆畜牧厅乌鲁木齐种牛场选择新疆褐牛121头,对其出生重、体高、胸围、管围、体斜长与产奶性能的资料进行分析,研究新疆褐牛的出生重、体高、胸围、管围、体斜长与产奶性能的相关性。结果表明:新疆褐牛的初生重对产奶量有显著的影响(P<0.05),新疆褐牛的体斜长对产奶量有显著影响(P<0.05);体高、胸围、管围对产奶量无显著影响。

121 Xinjiang Brown cattle were selected to study the correlation of birth weight, body height, chest circumference, cannon circumference, body slanting length with milk production. The resuits showed that the birth weight and body slanting length had significant effects on the milk production（ P〈0.05） while the body height, chest circumference and cannon circumference had no significant effects on the milk production （ P〉0.05）.
