Abstract
Purpose. Study and formation of new approaches in the development and justification of principles, methods and algorithms for the production of livestock products without the use of feed antibiotics. Materials and Methods. The objects of the study were: broiler chickens of the Ross 308 cross, quails of the Estonian breed, hybrid rabbits, sheep of the Edilbaev breed, laboratory rats and developed feed additives. During the research, all experiments were conducted taking into account the principles of bioethics. The research was carried out using standardized methods in accredited laboratories. The reliability of the results is confirmed by their processing by statistical methods. Discussion. Based on the results obtained, it can be concluded that the studied feed additives have a positive effect. Scientific and practical experiments have confirmed their effectiveness in feeding poultry and rabbits, and experimentally proved a stimulating and stabilizing effect on the body of the animals and poultry, which contributed to an increase in resistance, meat productivity and, as a result, the production of safe livestock raw materials. Conclusion. According to the results of the conducted studies, the expediency of using various plant extracts and bioflavonoids, feed additives containing alpha-monolaurin and a complex of organic acids, lactulose-based prebiotics in the cultivation of farm animals and poultry has been experimentally confirmed.
