Meat Productivity of the Ross 308 - Cross Roosters by the Adding in to a Diet of Organic Acids and their Salts

Abstract

Abstract The article presents the results of studies conducted on the inclusion of Presan and Selko pH feed additives produced on the basis of organic acids in the feeding diets of Ross-308 cross broiler chickens. Organic acids and their salts are used in poultry farming as an alternative to feed antibiotics, and also has the ability to prevent the development of intestinal bacterial infection, increase the resistance of the body, thereby improving the absorption of feed nutrients and increasing poultry productivity. The largest preslaughter weight was in the groups of cockerels getting the T6 diet without antibiotics adding, which is 1.92% more than the groups getting the T1-control diet. In addition, the output of the pectoral and femoral muscles was higher by chickens getting a T6 diet by 0.5 and 0.3%, in contrast to groups getting a standard diet. Thus, it has been experimentally proven that the tested feed additives Presan and Selko pH do not reduce the slaughter performance of broilers.
