RESEARCH OF CHEMICAL COMPOSITION OF ORGANIC CHICKEN MEAT

Poultry meat is considered the most complete and dietary, compared to other types of meat that are traditionally used in Ukraine. So the cultivation of organic poultry without antibiotics, growth stimulants, on clean feed should be a profitable and economically attractive direction. Natural prophylactic preparations for organic poultry farming were tested and their impact on the quality of the products obtained was assessed. Proposed use for organic cultivation of meat-egg breed of chickens, because males can be grown "for meat", and chickens to get egg productivity. A probiotic preparation was compared with the «Bacteriosan» postbiotic. The applied biological preparations successfully prevented diseases of chickens during organic farming, and are an effective alternative to antibiotics. The meat of chickens separated by sex was examined. The results of studies of the chemical composition of meat of cockerels and chickens showed that it corresponds to the proper characteristics of chicken meat. The chemical composition of the meat of cockerels was more stable and practically did not differ in research groups, therefore, the effect of the tested drugs on the quality of meat was not established. Mass fraction of protein, fat and moisture in the meat of chickens differed both in the experimental groups and from the meat of the cockerels. The concentration of macro and microelements in the muscles of organic chickens from the control and experimental groups did not exceed the maximum allowable levels. However, a slightly better assimilation of microelements occurred in the first experimental group of chickens who were drinking probiotic preparation. Thus, the results of the study of the chemical composition of muscle tissue indicate a more intensive metabolism of proteins, fats, and this in turn affects the mineral and water metabolism in the body of the chickens of the experimental groups. The use of prophylactic drugs, such as probiotic based on Lactobacillus plantarum strain and the postbiotic «Bacteriosan», has a positive effect on the productivity of poultry, as well as on the qualitative characteristics of chicken, in particular, improving the protein content of meat.
