Effect of Avigen immunomodulator on beta lysine activity in broilers

The beta-lysine activity of blood serum and egg white in broilers broiler breeders from the ROSS 308 hybrid reared industrial conditions was studied using a photometric method. birds experimental groups were treated with polybacterial immunomodulator "AVIGEN", anti-stress preparation "ASPIVIT C" "BIOXAN", which helps to increase resorption surface intestinal mucosa.We found increased immunomodulator-treated broilers. No significant differences control parent herds until onset lay. On lay, we observed an serum, especially pronounced herd. We also registered this indicator flock 2nd 7th day after laying. Elevated concentrations during legitimizes as stress-induced factor non-specific immunity. higher levels are probably due stimulation on mucous membranes AVIGEN.
