摘要
本试验选用22头奶牛,随机分为2组,在奶牛泌乳前期日粮中添加天然植物性添加剂,研究其对泌乳牛增乳效果及其血液活性T淋巴细胞和血清蛋白的影响。结果表明:1)在奶牛泌乳前期添加天然植物性添加剂,可使奶牛头日均泌乳量提高2．02kg(P<0．05),其提高率为5．53％,经济效益显著改善;2)可使血液活性T淋巴细胞极显著高于对照组(P<0．01),同时降低血清γ-球蛋白,提高A/G比值和血清白蛋白,但其差异不显著(P>0．05)。
Twenty two dairy cows were divided into two groups and natural plant additive was supplemented into the ration for cows at the lactating prophase to study the influence of natund plant additive on milk yield,T-Lymphocyte activity and serum protein content in blood.The results showed：1）Average daily milk yield increased by 2.02 kg per cow with the supplementation of natund plant additive,and the increase ratio was 5.53 %.2）The number of T-Lymphocyte in the treatment group was markedly higher than that of the control group （P 〈 0.01）.At the same time,the content of serum γ-globulin,the ratio of A/G and the content of serum albumin decreased,but the difference was not remarkable （P 〉 0.05）.
