| 摘 要： | 对于牧场来说,只有保持高产奶量和更多使用胎次,才能获得更高的奶牛饲养收益。多项研究表明,奶牛的使用胎次与生产性状之间存在显著的相关性。奶牛在3~5胎次时,其产奶量达到最高,牛奶品质较高。本文通过对使用胎次与奶牛生产性能的关系和影响奶牛使用胎次的因素进行分析,探讨增加奶牛使用胎次的改善措施,以期为现代化牧场确定奶牛淘汰胎龄,提高奶牛养殖收益提供参考。

| Abstract: | Maintaining high milk production and increasing the available parity of cow can bring higher feeding income to cow farm Studies showed that, there was a significant correlation between the milk production trait and the the parity of cow. As well as the total milk production peak at the 4~5 parity of cows, the composition of milk is good. In this paper, the correlation between the available parity and the production performance of cows, and the factors affecting the available parity of cows were analyzed, and the improvement measures of increasing the available parity of cows were discussed. In order to provide reference for the modern pasture to determine the available parity of cows and improve the yield of dairy farming. |
