EFFECT OF PARASITIC STRESS FACTOR THE DEFEAT OF CATTLE BY BOVICOLA BOVIS ON MORPHOLOGICAL PARAMETERS OF BLOOD IN CALVES

In this article are the results of research of the morphological parameters of blood of calves, affected tongs Bovicola bovis. Intensive defeat animal of Bovicola bovis had clinical manifestations, which were accompanied by a strong concern. Therefore, arthropods should be considered as stressors, that initiate typical change in the morphological composition of the blood, including decrease in hemoglobin level (P<0.05) and hypoeosinophilia. Also in the blood test group of calves was found a significant decrease, by 29.5%, the average white blood cells (7.67±0.65 g/L, P<0.05)
