摘要
为了解复方中草药添加剂对奶牛隐性乳房炎的防治效果和对奶牛泌乳性能的影响,对陕西省某规模化牛场2014年1月至2019年12月奶牛群改良(DHI)检测数据进行统计分析,对比该牛场自2016年10月使用复方中草药饲料添加剂前后奶牛隐性乳房炎发病率、305 d产奶量、日产奶量、泌乳持续力、泌乳高峰日、产犊间隔等的变化情况。结果表明,在使用复方中草药添加剂后,奶牛隐性乳房炎发病率显著降低(P<0.05),305 d产奶量极显著提高(P<0.01),日产奶量随季节交替波动幅度减小、泌乳持续力波动变小,且接近100%,泌乳高峰日显著后延(P<0.05),产犊间隔无显著变化(P>0.05)。说明在奶牛日粮中添加中草药饲料添加剂对奶牛隐性乳房炎具有一定防治效果,并能提高奶牛的泌乳性能。
In order to investigate the effect of compound Chinese herbal medicine additive on the prevention and treatment of subclinical mastitis and the effect of milk production performance in dairy cows,this study selected DHI(Dairy Herd Improvement)data from a dairy farm in Shaanxi province from 2014 to 2019 to analyze the incidence of subclinical mastitis,305-day milk yield,daily milk yield,lactation persistence,peak lactation and calving interval before and after the administration of compound Chinese herbal medicine additive in October 2016.The results showed that the incidence of subclinical mastitis was significantly decreased after the administration of compound Chinese herbal medicine additive(P<0.05).305 d milk yield was significantly increased(P<0.01),and the fluctuation of milk yield decreased with seasonal alternation,while the lactation persistence became stable and close to 100%.The peak lactation was significantly delayed(P<0.05),but there was no significant change in calving interval(P>0.05).The results indicated that the supplementation of compound Chinese herbal medicine had a certain prevention and control effect on subclinical mastitis and could improve the milk performance of dairy cows.
