日粮中添加巴尔吡尔对奶牛生产性能和经济效益的影响

摘要

The trial was finished in the high speed modern dairy farm, which studyed the effect of adding barr pyrazole to cow diet on the performance of dairy production in the summer heat stress period , and calculated comprehensive economic benefit after added barr pyrazole. The results showed that, compared with the control group, adding barr pyrazole to diet decreased the effect of heat stress on DMI, increased the milk yield and milk fat percent, decreased the somatic cell count in milk, had no significant effect on the milk protein percent and other indicators, increased the comprehensive economic benefits.%本试验研究了夏季热应激时期,在日粮中添加巴尔吡尔对奶牛生产性能的影响,并核算添加巴尔吡尔后对奶牛综合经济效益的影响.试验结果表明,与对照组相比,日粮中添加巴尔吡尔的奶牛,采食量受热应激影响减小,产奶量相对升高,乳脂率升高,牛奶中体细胞数减少,对乳蛋白等其他指标影响不大,综合经济效益增加.
