Abstract

The parameters for blood enzyme activities, clinical status, antioxidant defense, and cortisol and thyroxin concentrations in fresh cows in dry and postpartum periods were studied with the use of compound physiologically active substances having probiotic, antioxidant, adsorbent, and hepatoprotective properties. Positive changes in the animals fed the developed compound feeding stuff under the effect of feeding correction were revealed. Declined AST activity and the total bilirubin content, along with increased ALT activity and the lowered activities of gamma-glutamyl transferase and lactate dehydrogenase, in the animals of the experimental group were recorded. Thus, the total bilirubin content decreased by 35% (p < 0.05) and 40.4% (p < 0.01), the ALT activity increased by 10.3% (p < 0.001) and 12.0% (р < 0.05), and the activities of gamma-glutamyl transferase and lactate dehydrogenase reduced by 18.1 and 17.1% (p < 0.01) and 12.4 and 17.2% (р < 0.05), respectively. Positive changes in the antioxidant status of cows that consumed the complementary feed were ascertained. The average daily milk yields of cows in the control and experimental groups within the experiment comprised, on average, 31.73 kg milk containing 3.75% fat and 34.78 kg (p < 0.05) milk containing 3.78% fat, respectively.

奶牛后期干旱和早期泌乳期饲喂校正过程中的代谢特征

摘要

使用具有益生菌，抗氧化剂，吸附剂和保肝特性的复合生理活性物质，研究了干燥和产后新鲜奶牛的血液酶活性，临床状态，抗氧化防御以及皮质醇和甲状腺素浓度的参数。揭示了在饲喂校正作用下饲喂发育的复合饲料的动物的积极变化。下降AST活性和总胆红素含量，具有ALT活性升高和γ的降低的活动沿-谷氨酰转移酶和乳酸脱氢酶，实验组的动物的记录。因此，总胆红素含量分别下降了35％（p <0.05）和40.4％（p<0.01）时，ALT活性增加了10.3％（p <0.001）和12.0％（р <0.05），和γ的活动-谷氨酰转移酶和乳酸脱氢酶18.1和17.1％（减少p <0.01）和12.4和分别为17.2％（р <0.05）。确定食用补充饲料的母牛的抗氧化剂状态发生了积极变化。在该实验的对照组和实验组中，奶牛的平均日产奶量分别平均为31.73千克含3.75％脂肪的牛奶和34.78千克（p <0.05）含3.78％脂肪的牛奶。
