ДЕЙСТВИЕ СЕЛЕНСОДЕРЖАЩИХ ПРЕПАРАТОВ НА ФИЗИОЛОГИЧЕСКИЙ СТАТУС БРОЙЛЕРНЫХ ЦЫПЛЯТ

Abstract

The use of selenium-containing preparations "E-selenium", "Selplex" and "LovitVA + SE" in the diet of broiler chickens stimulates humoral non-specific protective factors, an increase in the number of erythrocytes, total protein, albumin, vitamin E, carotene and allows you to get high-quality products of meat origin from broiler chickens. At the first stage of research, it was established that the physiological status of Ross 308 day old chickens is characterized by a relatively high content of leukocytes and platelets in the blood, and stab and segmented pseudoeosinophils in the leukogram, which protect the body from adverse environmental factors. The content of such formed elements as erythrocytes is at the lower limits of the physiological norm. The concentration of hemoglobin in them is also low. The introduction of the drug "Selplex" into the diet contributes to an increase in such humoral non-specific protective factors as lysozyme and bactericidal activity of the blood serum of chickens. At the second stage of research, selenium-containing preparations "E-selenium" and "LovitVA + SE" were used for broiler chickens. The use of the drug "E-selenium" contributes to an increase in the content of erythrocytes and hemoglobin in the blood of chickens, the content of erythrocytes, in comparison with the control group, increases. Additional use of the drug "LovitVA + SE" leads to an increase in the level of erythrocytes in the blood of broiler chickens, hemoglobin, and also contributes to an increase in the concentration of total protein, albumin, vitamin E and carotene in the blood serum.
