MORPHOLOGICAL COMPOSITION OF BLOOD AND OXIDANT-ANTIOXIDANT SYSTEM IN COWS USING A PLANT COMPOSITION OF MARSH CINQUEFOIL AND CRANBERRY

The aim of the study is to investigate the effect of using a herbal composition of marsh cinquefoil and wild cranberry in feeding highly productive cows with stress-induced disorders in an industrial complex on the parameters of adaptation processes, including the oxidant-antioxidant system, the hormone cortisol and morphological parameters of blood in cows. Objectives: to prepare a herbal composition based on marsh cinquefoil and wild cranberry by mixing the components and re-grinding them to a particle size of about 5–7 mm; to study hematological parameters and oxidant-antioxidant status in cows kept in an industrial complex, the effect of the herbal composition on morphological parameters and the leukocyte count of blood in highly productive cows under industrial stress and the herbal composition based on marsh cinquefoil and cranberry on the antioxidant status and cortisol index in highly productive cows under industrial stress. The object of the study is Holsteinized cows kept in stressful conditions of an industrial complex. In cows fed only the basic diet, abnormalities in red blood cell counts, mean corpuscular hemoglobin content, and mean corpuscular hemoglobin concentration, as well as neutrophil and eosinophil levels were detected, while high malonic dialdehyde and low ceruloplasmin levels were detected in the blood serum, confirming the presence of oxidative stress. The addition of a marsh cinquefoil and cranberry composition to the basic diet of cows had a positive effect on the blood morphology of the animals in the experimental group. By the 21st day of the experiment, the level of eosinophils in animals of this group was (5.2 ± 0.98) %, neutrophils - (35.40 ± 0.92) %, erythrocytes – (5.77 ± 0.1) ∙ 1012/l, the average concentration of hemoglobin in an erythrocyte was (36.01 ± 0.72) g/dl, ceruloplasmin – (2.2 ± 0.13) μmol/l, which corresponded to the reference values.
