| 摘 要： | 本研究对新疆荷斯坦奶牛的产奶量与体型线性性状进行了相关、通径分析。结果发现，荷斯坦奶牛的乳房纵沟深、后乳房宽、后乳房高与产奶量呈中等正相关；体高、体长、尻宽、尻长与产奶量呈弱相关；后乳房宽、乳房纵沟深是直接影响产奶量的重要性状。

| Abstract: | Correlation and path analysis were applied to body Conformation linear traits and milk production in Holstein. The results showed that the depth of udder longitudinal ditch and the width and height of back udders had a moderate positive relative relationship with milk production, body height, body length, rump width and rump length had a weak relative relationship with milk production, back udder width and longitudinal ditch depth of udder, as the important traits of Holstein, had a direct effect on milk production. |
