We provided an inclusion of the mineral supplement as clinoptilolite (Nat-Min 9000, fraction 0-1 mm, 70 g per horse/day, Nat-Min 200, fraction 0-0.2 mm, 28 g per head/day) in the ration of sports horses and this was provided a positive effect on the body of experimental animals as evidenced by data of blood biochemistry. The studied blood values were within the physiological norms, the usage of clinoptilolite led to optimization of the biochemical profile of sports horses. The use of the adsorption additive Nat-Min did not adversely affect the concentration of fat-soluble vitamins A and E in the blood of experimental animals. At the end of the experiment, the concentration of vitamins A and E in the blood of the animals of the 2nd test group were above the control by 0.95 - 5.50 μmol/L and by 6.78 - 12.09 μmol/L (p < 0.05) in 3rd test group compared to the control. At the same time, the concentration of vitamin B2 in the horse blood of experimental groups decreased by 0.0037 μmol/ml (p <0.05) in 2nd experimental group and 0,0031 μmol/l in 3rd test group. The content of lysozyme in the blood of animals of the 2nd and 3rd test groups has increased relative to the control level by 0.13 and 0.16 μg/ml, respectively. Phagocytic activity in experimental groups has increased relative to control by 1.40%. A positive effect of the Nat-Min feed additive (fractions of 0-1 and 0-0.2 mm) on the physiological processes in the animals was also established. Variations of mineral additive fodder resulted in a generally equivalent positive biological effect, which makes it possible to recommend the use of clinoptilolite for horse feeding.
