新型奶牛预混料对热应激下的奶牛生产性能的影响

Effect of One New Type Dairy Premix on Milk Production of Dairy Cattle in Heat Stress

试验结果表明新型奶牛预混料能显著减缓热应激下奶牛产量的下降(p<0.05),试验组比对照组平均增加产奶量1.5kg/头、日,能显著降低乳中的体细胞数(p<0.05),改善奶牛的机体健康。

The result of the experiment showed that the new type premix can significantly improve the milk production of dairy cattle in the condition of heat stress (p<0. 05), the milk production increased by 1. 5kg/ head.d.the premix can significantly decrease the SCC in the milk(p<0.05), also, It indicated the premix could improve dairy cattle's health.
