The use of biologically active substances in poultry feeding (review)

Abstract. To obtain maximum benefits from poultry production, it is necessary to balance diets with biologically active components. An insufficient amount of them in diets helps to inhibit the processes of protein bisynthesis, reduces the immunological status and resistance of the body, which occur as a result of pathological changes in the organs and tissues of the deficient organism. The purpose of the study is to systematize the literature data on the use of various biologically active additives in the feed base of poultry, to increase its productive characteristics and improve the well-being of life. Methods. The work analyzes the research of domestic and foreign scientists on the used feed products, with the inclusion of biologically active substances necessary for the normal physiological development of poultry, obtaining maximum productivity and safety of the livestock. Internet resources used: RSCI – https://www.elibrary.ru, PubMed – https://pubmed.ncbi.nlm.nih.gov, also https://google.ru. Results. In the proposed review, thanks to a systematic analysis of the data obtained, one can judge the great interest of the world scientific community in organizing proper, balanced nutrition for poultry. It should be noted that the data provided on new drugs and feed additives entering the domestic market are the subject of a wide range of studies by modern scientists. This indicates a large number of publications in this direction. Scientific novelty. The review is presented taking into account new world developments in the field of feeding poultry, balancing diets with vital components to improve productive qualities and increase the body's resistance to various pathogens.
