Veterinary and sanitary assessment of broiler chicken meat when using feed probiotics in the diet
Introduction. In order to increase the production of poultry meat and reduce its cost, it is necessary to introduce advanced scientific achievements into production. The main factor affecting the productivity of birds is high-grade and good-quality feeding, which is achieved by adding biologically active substances to the diet. One of which is probiotics and prebiotics, which are widely used not only for the prevention of various diseases, but also for stimulating growth. Studies show that probiotics are widely used in poultry farming both as a biological regulator of metabolism in the poultry body and as productivity stimulants. If microbiological feed additives have been used for a long time, then living microorganisms began to be used relatively recently. The purpose of this work was to study the veterinary and sanitary indicators of broiler slaughter products when adding Royal Feed E-500 and Bioside feed probiotics to the diet. Materials and methods . The production experiment was carried out on 3 groups of one-day broiler chickens with 50 heads in each group. The first group received the Royal Feed E-500 probiotic with a diet at the rate of 4 % of the main diet, the second group received Bioside at the rate of 2.5 % of the main diet. The third group served as a control and was kept on a diet adopted by the farm. At the end of the experiment, the birds were slaughtered and the examination was carried out according to the Rules of veterinary and sanitary examination of meat. Results and discussion . On day 42, the live weight gain was higher in the experimental groups compared to the control by 2.52-3.7 %. During external examination of internal organs, pathological changes were not found in both experimental and control groups. In the experimental and control groups, the content of toxic elements, radionuclides, pesticides did not exceed MAL. During tasting assessment of the juiciness, aroma, tenderness and taste of the broth from poultry meat of the experimental groups, the scores were higher compared to the control. During microbiological studies, it was found that the pectoral muscles of all groups of broiler chickens were contaminated to a lesser extent than the femoral ones. Conclusion . Probiotic preparations Royal Feed E-500 and Bioside for broiler chickens does not cause pathological changes and improves the quality of slaughter products according to organoleptic, physico-chemical and bacteriological indicators, which meets the requirements of GOST for good-quality meat.
