PREMIXES IN FEEDING SPORT HORSES
The effect of the Panto Vit Standart premix on the functional and morpho-biochemical parameters of sport horses of the equestrian sport school of the Olympic reserve of the North Zauralye State Agrarian University has been studied. The imbalance of diets led to serious disruptions in the functioning of the whole organism. The inclusion of the premix into the horse diet made possible the balance of the missing substances in it. After completion of feeding the premix, it was found that the level of hemoglobin in animals' blood had increased by 3.91% and the concentration of erythrocytes - by 7.71% compared with the control. The use of the premix had a positive effect on the animals' adaptation to physical exertion and the intensity of metabolic processes, while an increase in the heart rate and the level of erythrocytes and hemoglobin was observed. This indicated that the horse organism was highly labile in response to the use of biologically active substances.
