Study of the influence of the vitamin and mineral supplement evitsel on the organism of broiler chickens

The article presents the data on the use of the domestic vitamin and mineral supplement Evitsel produced by Brovapharma on the body of broiler chickens. As a result of the research, it was found that the vitamin-mineral supplement, when added to the diet in accordance with the guidelines, affects the hematological parameters and biochemical parameters of broiler chickens on day 10, manifested by an increase in the number of pseudo-esophophils and lymphocytes, and on day 20 only lymphocytes. However, by day 30, the general blood counts (number of red blood cells, leukocytes, hemoglobin, platelets) and leukogram did not have a significant difference with the control group. In the study of biochemical parameters of blood serum, it was found that total protein on day 10 was significantly different from the control group, but in further studies, its level, as well as the level of other biochemical parameters of blood serum, did not exceed the physiological norms. Studies of the natural resistance of broiler chickens showed that when Evitsel was added to the diet, the phagocytic index increased by 0.7%, phagocytic activity by 7.4%, lysozyme activity by 5.7%, and bactericidal activity by 7.4% compared to the control group. It has been established that the use of this additive contributes to the increase of natural resistance of broiler chickens and can be used in industrial poultry farming
