选取24头中国荷斯坦奶牛经产泌乳母牛,随机等分为A、B、C、D四组,分别每头静脉注射经生理盐水溶解的Zn-MT 0 (对照),4.0,8.0和12.0 mg,以探讨外源性金属硫蛋白(MT)对奶牛泌乳性能和血清抗氧化状况的影响.结果表明,C和D组的4%标准乳产量均显著高于对照组(P0.05).B、C和D组血清谷胱甘肽过氧化物酶(GSH-Px)活性均显著高于对照组(P

The effects of exogenous metallothionein（Zn-MT） on milkability and anti-oxidative status of dairy cattle was studied using 24 lactating Chinese Holstein cows.They were randomly allocated to groups A,B,C,and D,and Zn-MT was supplemented at 0,4.0,8.0 and 12.0 mg/capita respectively by intravenous injection.The milk yields of the cows in groups C and D were higher（P〈0.05） than those in group A,but there were no significant differences in milk yields between groups A and B or in milkfat percentages between groups.The blood GSH-Px activities of...
