Anti-stress drugs in broiler chicken diets

Currently, one of the problems of industrial poultry farming is the discrepancy between the parameters of growing and keeping chickens and their biological needs, which leads to the development of a stress reaction. A common method of preventing stress conditions in birds, aimed at forming socially stable production groups, is pharmacorrection. The purpose of the conducted studies was to determine the effectiveness of using various anti-stress feed additives and their combinations when growing Ross 308 cross broiler chickens. For this purpose, a scientific and economic experiment was conducted, during which broiler chickens were fed anti-stress drugs - fumaric acid at a dose of 200 g / t of feed and GABA at a dose of 25 g / t of feed, as well as their combination from the age of 8 days of chickens until the end of their growth. During the research, the influence of preparations with an anti-stress effect and their combination on the zootechnical indices and stress sensitivity of broiler chickens was assessed using the turpentine test with the study of the leukogram. To increase the stress resistance of broiler chickens and the efficiency of their cultivation in industrial conditions, we recommend using fumaric acid at a dose of 200 g / t of compound feed.
