The purpose of the work is to develop methods of using biologically active substances in egg incubation. Research methods - microbiological, zoo technical, embryological, statistical. Methods of disinfection of hatching eggs with the use of environmentally friendly substances have been improved. Studies have shown the high efficiency of environmentally friendly solution of "Sumerian silver" when used for pre-incubation disinfection of chicken and turkey eggs. At a concentration of 3.0%, this solution effectively reduces the microbial contamination of the shell, which has a positive effect on the hatching of eggs and the sanitary condition of the incubator. The solution has no contraindications and special precautions for staff during use. It was found that the use of propolis for pre-incubation disinfection of eggs with subsequent treatment on 11.5 and 18 days of incubation with propolis or aqueous infusion of calendula leads to an increase in egg hatchability by 4.4-5.2% compared to control. In addition, it is also acceptable to use a solution of echinacea infusion for pre-incubation disinfection of eggs in combination with the subsequent treatment of eggs on the 18th day of incubation with echinacea or calendula infusion: hatchability of eggs in these groups exceeded the control indicator by 0.4-1.3%. The use of beta-cyclodextrin in combination with infusions of echinacea and calendula to enhance the effect of the solutions used in our experiments did not lead to the expected effect. During the opening and the analysis of the incubation wastes, the pathological picture of dead embryos did not reveal signs of microbial contamination of egg contents, indicating the high effectiveness of the solutions used.
