摘要
研究分两个试验,探讨夏季高温热应激的情况下,反刍动物专用复合酶对奶牛产奶量的影响。综合两个试验的研究表明,在奶牛精料补充料中添加反刍动物专用复合酶,与对照组相比可以缓解奶牛夏天的热应激,提高产奶量,适宜添加量为200 g/t。
Two experiments were arranged to research the effect of compound enzyme on milk produc- tion of cows under summer heat stress. The results of the two experiments show that, in summer, the addition of compound enzyme to the TMR of cows can relieve the heat stress of cows and enhance the milk production. The optimum dosage of compound enzyme in the TMR is 200 g/t.
