摘要
通过对奶牛的产奶量、胎次和血清蛋白的分析和测定,结果表明,奶牛的产奶量随着胎次(1～6胎)的增加而逐渐增加;血清总蛋白、球蛋白的含量也随胎次及泌乳量的增加而升高;产奶量与总蛋白含量间成中等直线正相关(P<0.05);而白蛋白在高、低产组的变化与产奶量的差异不显著(P>0.05),A/G值随泌乳量增加而降低,α球蛋白也有相同趋势,但r球蛋白变化不显著。
The result showed that in treated cows the output of milk increased with the increase of the babies. And the total protein and globulin in serum was increasing with the increases of the babies and milk output too. The corrlation of the output of milk relating to total protein in serum was significant (P<0.05). The correlation coefficient was 0.33 respectively.But the difference between the albumin and globulin content in serum and the output of milk was no significant.A/G value was decreasing with the increase of the output of milk and α-globulin showed the same tendency but the changes of r-globulin content were not marked.
