CHANGES IN HEMATOLOGICAL BLOOD PARAMETERS IN HORSES PARTICIPATING IN EQUESTRIAN DISTANCE RUNS

Abstract

The article provides information on the impact of training on clinical blood parameters in horses participating in equestrian distance running competitions, the distance length is 40 km. The animals were divided into two groups, 10 heads each. The first group included horses that were trained one week before the races, the second included animals that were trained two weeks before the competition. As a result of the research, it was revealed that in the case of training within one week before the competition, horses had a statistically significant increase in the number of segmented neutrophils compared to the indicators before the start. This is probably due to the fact that with heavy physical exertion, muscle tissue begins to be injured in insufficiently trained animals, as a result of which the body needs to dispose of the products of muscle tissue metabolism. During the training for two weeks before the competition at a distance of 40 km, the level of segmented neutrophils in the blood of horses did not differ from the data before the start. An increase in red blood indicators was determined in all experimental horses after the runs, when compared with the data before the load, but these indicators did not go beyond the reference values. This is probably due to dehydration, which often develops when walking a long distance. There was also a statistically significant decrease in the level of lymphocytes after exercise in both groups of horses when compared with the indicators before the start. At the same time, these indicators did not go beyond the reference interval.
