【 摘 要 】

The main purpose of the study was to study the effectiveness of water-soluble antioxidants on thephysiological and zootechni cal indicators of egg incubation and offspring hatchability.The research was carried outon two groups of laying hens of a custom herd, selected by random sampling of one hundred heads per group. For41 days, the experimental group of chickens received a basic diet enriched with dihydroethoxychine (DGE), in orderto increase the antioxidant status at a dosage of 100 mg/kg of feed. Sampling was performed from the axillary veinon the 25th day of application of the additive (n=5) for physiological and biochemical studies. In the course of thestudy, it was determined that in the experimental group, the concentration of cholesterol in the fraction of highdensity lipoproteins increased twofold (P<0.01) and in the fraction of low-density lipoproteins decreased by almost50% (P<0.01) against the control. The concentration of malondialdehyde (MDA) in the blood of chickens in theexperimental group was 82.00% relative to that in the control, and in the yolk of the egg - only 37.42 %. Eggproduction of chickens in the experimental group was higher than in the control by 7.3% (P<0.1). Hatchability ofchickens in the experimental group increased by 14.6% (P<0.01) relative to control. It was concluded that the testedwater-soluble antioxidant has a positive effect on the biological functions and productive parameters of laying hens.
