不同抗热应激添加剂对奶牛生产性能的影响

The Influence to Milk Cow's Productive Function of Different Thermoresistant Stress Additive

本试验研究了不同抗热应激添加剂对泌乳牛生产性能的影响,试验分四个处理,每个处理10头奶牛,A处理为对照组,喂以基础日粮,B处理在A处理基础日粮上添加维生素C(1000～1600mg/日·头),C处理在A处理基础上添加电解质(NaHCO30.03kg/日·头,KCL0.03kg/日·头,NH4CL0.03kg/日·头),D处理在A处理基础上添加中草药添加剂(75g/日·头)。试验结果表明,在产奶量方面,添加中草药处理组效果最好,与对照组、维生素组、电解质组差异极显著(P<0.01);其次是电解质组较好,与对照组、维生素组差异极显著(P<0.01):维生素组最差,与对照组比较,差异不显著(P>0.05);在投入产出比方面,中草药组最好,其次是电解质组。

The experiment is to study the influence to milk cow's productive function of different thermoresistant stress additive, experiment torberdivided four groups, and each one group 10 heads milk cows.A group is control group,feeding with foundation diet,B group is feeded with vitamin C (1000-1600 mg/ day · head) on the basis of foundation diet;C group is feeded with electrolyte(NaHCO3 0.03kg/day · head, KCL0.03kg/day·head,NH4CL 0.03kg/day · head) on the basis of foundation diet;D group is feeded with herb medicine(75 g/day·head).The result of experiment is that,with regard to milk quantity, herb medicine group is the best,increased obviously(P<0.01) compared with vitamin C group, electrolyte group,electrolyte group in the next place, increased obviously(P<0.01) compared with vitamin C group,vitamin C group at the latest,changed less with the control group. With regard to the ratio of output from investment, the herb medicine group is best, and the next in order is electrolyte group.
