The metabolic profile of blood serum of sport horses in the conditions of physical and emotional stress

Abstract

The data on dynamics of metabolic parameters level in the blood serum of sport horses of the Ukrainian riding breed at physical and emotional stress conditions are presented. Clinically healthy horses were objects of the research. The samples of blood were taken from the jugular vein to get serum for further biochemical research in the condition of relative rest, after ordinary training and after emotional stress during the entertaining performance with participation of a large number of people and loud music. In comparison with the control group, during training total protein content in blood serum increased by 11.1% and the level of urea did not change; under emotional stress total protein decreased by 8.7%, the level of urea reduced by 18.7%. Alanine aminotransferase activity during exercise increased by 20.8%, while at emotional stress decreased by 13.8%. At training creatinine increased by 18.6%, while at emotional stress it did not change. Bilirubin and alkaline phosphatase activity during physical training did not change and under emotional stress increased by 93.1 and 24.3% respectively. Ferum level fell at mechanical load by 10.5%, at emotional impact it increased in the same degree. The concentrations of uric acid, glucose, and cholesterol during training increased by 13.7, 42.9 and 7.1%, at emotional stress – by 79.4, 19.0 and 26.2% respectively. Emotional impact is a more strong stress factor that causes negative changes of metabolic profile parameters.
