The effect of bolus based on propolis and rhodiola rosea on the leukocyte formula of blood in cows when adapting to the conditions of stressful industrial technology

The article shows that cows kept in the industrial complex have been found to have a stress reaction, manifested in an increase in the level of malondialdehyde and a violation in the leukocyte formula of the blood. The aim of the work was to study the effect of boluses based on propolis and rhodiola rosea on adaptive processes in Holstein cows under technological stress, whose condition was determined by the level of malondialdehyde and indicators of the leukocyte blood formula, a violation of which is an established fact during the development of a stress reaction. In our experiment, a stress state characterized by a high level of malondialdehyde was found in Holstein cows located in an industrial complex. A decrease in free radical oxidation by the level of malondialdehyde was established using our products, which confirms the antioxidant-adaptogenic effect of boluses based on propolis and rhodiola rosea. After the use of boluses based on propolis and rhodiola rosea, positive changes in the leukocyte formula were also established in Holstein cows. The number of neutrophilic leukocytes in the blood of Holstein cows kept under industrial stress before the use of the supplement was 7.5% higher than the upper limit of the norm, and after application there was a positive trend in their decrease, so in the first experimental group the level of neutrophils decreased by 7.5%, and in the second - by 8%, compared with the control group. Stabilization of eosinophils relative to the beginning of the experiment was also noted, which was manifested in an increase in them in cows in experimental group No. 1 - 33.3%, in experimental group No. 2 - by 2 times.
