摘　　要：为探讨新疆北疆地区西门塔尔牛的产犊月份对泌乳量的影响,以新疆呼图壁种牛场牧二场饲养的西门塔尔牛为研究对象,分析了不同产犊月份对305 d的产奶量的影响。结果表明:12月份产犊的母牛305 d产奶量最高,且与5月份、9月份、11月份产犊的牛305 d产奶量存在显著差异(P<0.05),与7月份、8月份、10月份产犊牛的305 d产奶量存在极显著差异(P<0.01);3月份产犊的母牛305 d产奶量次高,与夏季的7月份、8月份的奶产量相比差异显著(P<0.05)。因此合适的产犊季节有利于提高牛群的产奶量。In order to explore the effect of calving month on milk production of Simmental in the northern region of Xinjiang, the Simmental eattles from second ranch in Hutubi herd farm were selected,and the effect of different calving months on 305 milk production were analyzed by One-way ANOVA. The results are as follows： the cows calving in December has the highest 305-day milk yield,with a significant difference （P ,0.05） in comparison to cows calving in May,Sep. and Nov. ,with an extreme difference （P 〈0. 01） compared with the cows calving in July,Aug. and Oct. the cows calving in March has the second highest 305-day milk yield, the difference with July, August had a higher level of significance （P （0.01）. Therefore, the appropriate calving season is favorable to increase the milk yield of cattle.
