摘要
为研究慢性冷应激对荷斯坦奶牛乳清生化指标和酶活性的影响。结果显示,随着环境温度的下降,乳清ALB、BUN、P含量呈升高趋势;TP、Ca含量降低;Glu、CHO含量无显著性变化(P>0.05);ALT、AST、ALP和LDH活性下降。表明慢性冷应激可引起奶牛乳清中某些生化指标和酶活性的变化。
In order to observe the effect of chronic cold stress on biochemical indicators and enzyme in whey in Holstein lactating cows.The results showed that following the decreased of environmental temperature,the concentration of ALB,BUN,P in whey tended to rise,and TP,Ca tended to decreased,but there was no difference in Glu,CHO in groups（P0.05）.The activity of ALT,AST ALP and LDH in serum tended to decrease.It is suggested that some biochemical indicators and enzyme in whey in cows are changed with the chronic cold stress.
