【摘要】 采用三种浓度(4.5%、5.5%和6.5%)的精氨酸对108头奶牛进行产母犊率试验.结果显示,试验组比对照组提高8.9%～13.34%,以5.5%精氨酸浓度最为明显,两者差异显著(P<0.05),而试验组之间差异不显著.在情期受胎率方面,试验组与对照组比较,试验组低于对照组,两者差异显著(P<0.05).更多还原

【Abstract】 Three kinds of density of arginine were adopted to test the female newborn calves produced by 108 milk cow. The results showed that there was a significant difference between the experiment group and control group (P<0.05) and no difference between experiment group.The experiment group was higher than control group. There was no significant difference between experiment group and control group in cycle conception rate(P<0.05).更多还原
