Probiotic drug based on Bacillus Amyloliquefaciens as an alternative to antimicrobial drugs in broiler chicken diets

Abstract

This article reflects on the issue of adequate poultry feeding and the case of refusing antimicrobial drugs when growing broiler chickens. Antimicrobials use in poultry diets is directly related to the actual problem of our time - antibiotic resistance. Many antibiotics, actively used in poultry farming before, gradually lose their effectiveness - bacteria begin to suppress their action and even completely neutralize the medicine. Diseases start to occur in a more acute form. The theoretical and practical significance of the study is based on the rejection of antimicrobial drugs when a probiotic pill with antagonistic properties to pathogenic microorganisms is added to the diet of broiler chickens. The article presents the key points of the study and the results of laboratory and practical experiments to identify the antagonistic activity of a probiotic preparation based on bacillus amyloliquefaciens to pathogenic microorganisms. The research methods on which this article was based are laboratory and practical experiments, scientific and economic experiments, and statistical data analysis. The first stage of research is laboratory tests confirming the drug’s antagonistic activity and the active substance’s survival when passing through the acidic environment of the bird’s stomach. The second research stage was a scientific and economic experiment on a small number of broiler chickens. The authors proved the antagonistic activity of the probiotic preparation based on bacillus amyloliquefaciens based on the results of this study. In addition, the authors confirmed the possibility of using the drug in the diets of broiler chickens as an alternative to antimicrobials.
