摘要: 为探讨上海地区季节性变化对奶牛产奶量的影响,笔者采集2006年1月~2007年10月基础产奶量数据共17284牛次,分析季节变化对奶牛生产性能的影响。结果表明,12、1和2月份分娩的母牛产奶量较高,7、8、9和10月份分娩的母牛产奶量较低,其他月份居中;10、8、7和9 月份4个自然月产奶量极显著低于其他月份,其中9月份最低,而其他各月份差异不明显;奶牛分娩后不同泌乳月份产奶量由高到低的顺序是2、3、4、1、5、6、7、8、9、10和大于10个月龄。季节对奶牛的产奶性能有明显影响,应根据季节制定不同的饲养管理任务和采取相应的饲养措施,同时建议对奶牛的DHI记录也应考虑季节的影响。

Abstract: The objective of this study was to investigate the effect of seasonal changes on milk yield in Shanghai district. The seventeen thousand two hundred and eighty four milk yield records were analyzed. The milk yield of cows calved in December, January and February was higher, but lower in July, August, September and October and the lowest in September. The milk yield of cows by nature month was significant lower in July, August, September and October than others and there was no difference among the others. The milk yield is lower down from 2, 3, 4, 1, 5, 6, 7, 8, 9, 10 to >10 months according to postcalve month. It showed that the seasonal changes can affect milk yield significantly and should make goals and management way by difference season. The DHI records should contain the information of season.
