热应激对奶牛的影响及应对措施

Physical Cooling Measures to Reduce Heat Stress in Dairy Cows

热应激会降低奶牛干物质采食量、生产性能,并提高呼吸速率,以维持体内温度。当奶牛经受热应激时,应当采取切实有效的措施,使奶牛能够发挥其生产潜力,提高牧场盈利。本综述对减少奶牛热应激负面影响的相关措施进行了总结。

Heat stress reduces dry matter intake,production performance,and increases respiratory rate to maintain body temperature in dairy cows.When cows are subjected to heat stress,effective measures should be taken to enable cows to exert their production potential and improve the profitability of pastures.This review summarizes the relevant measures to reduce the negative effects of heat stress on dairy cows.
