摘要
为了探索麦洼牦牛泌乳的变化规律,收集了四川龙日种畜场2003-2009年间产犊母牦牛的产奶数据,分析了暖季牦牛泌乳的变化规律.结果表明,产犊后30～70 d时,牦牛日产奶量逐步升高,70～110 d时达到高峰期,110d后日产奶量逐步降低至不挤奶;麦洼牦牛日产奶量受年度效应的影响较小;不同日龄的挤奶量之间相关性较强.
The lactation change of the Maiwa yak were studied based on the data of locating longri yak during 2003-2009.The results showed that the milk yield was increasing gradually during the 30～70 days after calving,and reached the peak during the 70～110 days,and decreased gradually to no milking after the 110th day.The milk production of Maiwa yak was less influenced by the year factor but had strong correlation with the lactation age.
