INFLUENCE OF PHYSICAL AND EMOTIONAL ACTIVITY ON THE METABOLIC PROFILE OF BLOOD SERUM OF DRESSAGE HORSES OF THE UKRAINIAN RIDING BREED
Efficiency of use of a dressage horse is caused by a complex of factors. Special attention is paid to the state of health of a horse and its ability to recover after physical activity (training) and emotional loading (stress). In this case biochemical methods give a chance to define reasonable adaptation potential of a horse with various types of loading. The data of dynamics of the level of indicators of a metabolic profile of blood serum of dressage horses in the conditions of physical and emotional loading are given in the article. Clinically healthy horses were an object of the research. Blood was taken from a jugular vein to get serum and for further biochemical research. For the research 9 horses were chosen out of 57 examined sport horses of the Ukrainian riding breed according to a regimen of trainings and demands in dressage competitions. Blood was taken in a 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. Calculations of the received results were carried out on personal computer by means of the statistical program STATISTICA 7.0 (StatSoft, USA) with determination of arithmetic mean (M), an error of the average (m), limits (Lim) and the confidenсe intervals (CI) for p <0.05, <0.01, <0,001. Inblood serum the following biochemical indicators were determined: whole protein, urea, creatinine, uric acid, total bilirubin and its fractions, glucose, cholesterol, triacylglycerol, calcium, Ferum, lactate, pyruvate, activity of the ALAT, SGOT, GGTP, LDH, an alkaline phosphatase - which give a chance to determine reasonably adaptation potential of a horse with various types of loading. It was established that during training and psychoemotional loadings of sport horses of the Ukrainian riding breed which were selected according to a regimen of trainings and demands in dressage competitions multidirectional changes of level of biochemical indicators of blood serum were observed, which is an evidence of the tension of metabolic processes in organism of an animal. Emotional loading is a strong stress factor that causes negative changes in indicators of a metabolic profile. During the trainings and tests of horses in this kind of equestrian sport trainers should take it into account in order to facilitate the adaptation of a horse under the influence of various stress factors, to correct physiological state of an animal, and it will give an opportunity to a horse to overcome intensive loadings without threat for its health and it will also help to achieve good results during competitions in dressage.
