Application of microbiological feed additives in feeding of broiler chickens

The input of restrictions on the use of antibiotics makes it necessary to take a fresh look at the problem of safe production of food products in the poultry industry. Reduction in the use of antibiotic growth promoters can be achieved through the introduction of new technological solutions. The purpose of the work was the scientifi c and industrial justifi cation for the application of Profort® and Probiocid®-Ultra feed additives in the diets of industrial herd of broiler chickens. As a result of the work probiotic microorganisms included in the feed additives their potential role and safety in ensuring the well-being of health and optimizing digestion processes when rearing broilers were studied. The practical significance of Profort® and Probiocid®-Ultra additives and the possibility of their use instead of feed antibiotics were studied. The feasibility of combined use of Profort® and Probiocid®-Ultra additives was proven. The use of these feed additives allows us to abandon the use of feed antibiotics while maintaining the productivity and health indicators of poultry and at the same time increase the efficiency of feed resource use. The feed additives Probiocid®-Ultra and Profort® had a positive effect on the productivity of broiler chickens. The inclusion of these additives allowed to increase the survivability of chickens by 2.5 abs.%, reduce feed intake per unit of output by 19 g and obtain 6905 kg or 4.0 % more output in live weight, i.e. 3885 kg or 2.6 % more meat for sale. It is recommended to introduce Profort® feed additive (0.5 kg/t of compound feed) together with Probiocid®-Ultra (1 kg/t of compound feed) into the diet of broiler chickens with limited use of feed antibiotics in order to increase the survivability of broiler chickens, average daily live weight gain, slaughter weight and reduce feed costs.
