Морфобиохимические показатели крови и активность ферментов обмена углеводов в тканях коров при антропогенной нагрузке
Abstract
The aim of our research was to study the dynamics of blood morphological and biochemical characteristics, as well as the activity of carbohydrate metabolism enzymes in the tissues of cows that are exploited in a biogeochemical area with elevated concentrations of heavy metals in water and feeds, on the background of the use of zeolite as a feed additive. The findings from this study demonstrate that heavy metals, which penetrate into the body of cows with the feeds, affect the enzyme activity of different animal organs differently. The enzymes located in the liver are inhibited most, and those located in the skeletal muscles are inhibited least.The use of zeolite flour as a feed additive for 180 days had a positive effect on blood haematological parameters and carbohydrate metabolism in the organs of cows, as manifested by the recovery of the activity of certain carbohydrate metabolism enzymes. Thus, lactate dehydrogenase activity was recovered most of all with the total percentage of 50.0% (liver - 28.6%, heart muscle - 12.5% and skeletal muscle - 8.9%).
