摘　　要：奶牛热应激,一直是影响现代化牧场效益的主要因素,尤其是在夏季最热时候。热应激不但影响奶牛干物质采食量,而且影响奶牛后续生产。提高热应激期间奶牛干物质采食量,一直是困扰现代奶牛场的主要问题之一。本文研究热应激期间调整奶牛饲喂方式对奶牛干物质采食量的影响。试验表明,夏季热应激期间,通过调整奶牛饲喂时间、增加饲喂次数,分别提高奶牛干物质采食量0.52 kg、0.80 kg,提高奶牛产量1.00 kg、1.31 kg。Heat stress has always been the main factor affecting the benefits of modern pasture, especially in the hottest time in summer. Heat stress not only affects the dry material intake of cows,but also affects the subsequent production of cows. Improving the dry matter intake of dairy cows during heat stress has been one of the main problems puzzling modern dairy farms This paper studied the effect of adjusting dairy cow feeding mode on dry material feed intake during heat stress. The experiment showed that during the summer heat stress period,by adjusting the feeding time and increasing the feeding times,the dry matter intake of dairy cows was increased by 0.52kg and 0.80 kg,and the yield of dairy cows was increased by 1.00 kg and 1.31 kg respectively.
