Cows blood indicators when including humic acid supplements in the diet

Tasks: assessment of the effect of a biological product on the level of metabolic processes in the body of animals and analysis of the health status of cows according to the physiological parameters of the blood. The studies were carried out in the conditions of the stud farm-collective farm named after the 50th anniversary of the USSR in the Vologda Region. For these purposes, 30 cows were selected; for 90 days, the preparation Reasil Humic Health was included in the feeding of animals individually at 30 g per day. It has been established that feeding supplements based on humic acids had a positive effect on the physiological state and metabolic processes in the animal body. So, in cows after the end of feeding the drug, an increase in the content of albumin in the blood by 6.9 % (p˂0.01), glucose by 15.2 % (p˂0.01) and calcium by 12.4 % (p˂0.001) was noted. In addition, there was a decrease in urea and cholesterol by 5.0 and22.0 % (p˂0.05), respectively. When analyzing hematological parameters of blood, an increase in the concentration of hemoglobin by 8.7 %, erythrocytes by 1.9 and lymphocytes by 7.3 %, as well as a decrease in the content of leukocytes by 25.8 % was noted.
