THE STUDY OF COWS’ METABOLIC STATUS WHEN APPLYING PREVENTION SPECIMENS

In the dry period, cows have fetoplacental insufficiency caused by endocrine metabolism disorder and antioxidant protection systems disturbance, which affects fetal development and leads to complications of labor and postnatal processes. Еру specimens based on humic substances and probiotics are widely used to correct the metabolic status of cows during the critical physiological periods. The research implies application of Cytogumat® to the experimental groups of animals when they were injected 30 - 40 days before calving during three weeks; Fometrin was applied during 3 days after birth. The animals in the control group received Gabivit-Se 2 times before calving with an intervals of 15 days, and Rebavagin specimen after calving 4 suppositories 3 times a day. The authors found that the cholesterol parameter increased by 27.1 and 16.9% in the 1st and 2nd experimental groups of cows by the 15th day after calving and exceeded that in the control group by 20% averagely, while the activity of aspartataminotransferase (ACT) was lower by 18.4 - 25.9%, and the coefficient of de Rytis was 1.5 times lower than in the control group. On the 40th day of the postnatal period, the authors observed higher concentrations of bilirubin in the experimental groups a decrease in level by 1.8 - 2.6 times, triglycerides - by 13.6 - 22.7%, while the cholesterol/triglyceride ratio was 1.6 - 2 times higher than in the control group. Lower concentrations of cholesterol and higher concentrations of ACT in blood serum of the control group cows are explained by the increased functional load on the liver in the early lactation period accompanied by the hormonal rearrangement and increase in milk productivity. The authors observed faster recovery and strengthening of metabolic processes in the experimental groups of animals.
