Abstract

In the course of the study, the analysis of clinical and hematological parameters of blood serum, characterizing protein metabolism in racehorses with pathologies of the cardiovascular system, was carried out. Physical activity caused them: an increase in the number of erythrocytes by 19,2%, hematocrit – by 15,6%, hemoglobin – by 18%, urea – by 6,4%, alpha-globulins – by 33%; decrease in beta and gamma globulins. Hyperchromaemiawas revealed: an increase in the hemoglobin content in the erythrocyte was 11% above the norm before work and by 13,5% after work. A violation of the ratio of protein fractions in blood was found: at rest, the proportion of alpha globulins is 16,9% below the norm, the proportion of beta globulins in the blood exceeds the upper limit of the norm by 7,5%, and gamma globulins – by 28%; after exercise, the proportion of alpha globulins increases by 33%, and gamma globulins decreases by 37,6%.
The analysis of the correlation of blood parameters at rest revealed an inverse relationship between the level of erythrocytes, hemoglobin and the amount of transport proteins in the blood plasma (albumin and alpha globulins); physical activity caused a decrease in the correlation dependence.
