为研制一种有效的奶牛抗热应激添加剂, 将50头健康荷斯坦奶牛随机分为5组, 对照组饲喂基础日粮, 4个试验组饲喂基础日粮添加不同抗热应激添加剂, 连续饲喂30 d, 测定产奶量、生理及血液指标。结果显示: 中草药组、中草药+纤维素酶组、中草药+缓冲盐组、中草药+缓冲盐+纤维素酶组比对照组产奶量分别提高24.8 %、27.9 %、37.2 %、39.5 %; 中草药剂和缓冲盐可减缓热应激奶牛的体温(P>0.05)、呼吸和心率(P0.05), heart rate and respiratory frequency(P

In order to research a kind of effective anti-heat stress additive for cow, 50 healthy Holstein Cows were divided randomly into five groups. The control group was fed with basal diet, four test groups had been fed with basic diet and different anti-heat stress additives for continuous 30 days, then the milk yields, physiology and blood indexes were determined. The results showed ： as compared with the control group, the four test groups improved respectively with mild yelds of 24.8 % ,27.9 % ,37.2 % ,39.5 %. The chinese herbal medicine agent a...
