Correcting lipoperoxidation processes and stimulating growth in young chickens with the use of biologically active additives based on the organic form of selenium and vitamin C
The aim of the study was to study the possibility of correcting the hematologic profile and improving the quality of development of the young chickens with the use of transovarial treatment of incubating eggs with a preparation based on the organic form of selenium and vitamin C. The experimental batch of hen eggs of the Shaver White Cross (n=300) was treated twice with water spray irrigation solution of the drug Selen-Active (Diode, Moscow Ecological Plant, Russia), containing the organic form of selenium (Seleksen) and vitamin C at a concentration of 0.1 and 1% before incubation and on the 19th day of incubation, respectively. In the control lot, no treatment was performed. It was shown that transovarial treatment of eggs caused a decrease in the level of lipoperoxidation and excessive formation of cytotoxic products in chickens. In the experimental group, antioxidant activity (P<0.001) increased in the blood serum of the day, the content of Schiff bases decreased (P<0.01), which largely determined the optimization of the hematologic background. This was reflected in an increase in the color index, blood hemoglobin level, hemoglobin content in erythrocyte and mean erythrocyte volume, number of segmented neutrophils (young forms were absent) with a decrease in the content of eosinophils and erythrocyte sedimentation rate. The obtained data indicate an increase in the efficiency of oxygen transport by red blood cells and more complete tissue trophic, which helps to prevent deformability of erythrocytes, development of pathological microvesicle and autoimmune processes. Optimization of the hematologic background in the body of chick embryos had a positive effect on the quality of development of the young chickens and its viability.
