A relevant issue in poultry farming is the use of various probiotics and feed additives that positively impact gut health and its microbiota, which in turn promotes the growth and development of birds. In a scientific-farm experiment, the productive effects of the probiotic Acidofilin V-143 and the feed additive Suvar were compared in the diets of Cobb-500 broiler chickens. Their use in broiler feeding up to 37 days increased slaughter weight by 3.8%. Feed input norms were established, and gains in live weight and meat quality were determined, alongside new indicators for the chemical composition and nutritional value of the chicken meat. A tasting evaluation was also conducted to determine the flavor qualities of broiler meat. The application of the probiotic Acidofilin V-143 and the feed additive Suvar increased the flock's survival rate by 3.0% and 5.0%, respectively.}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
