E.V. Krapivina¹, D.V. Ivanov¹, A.I. Fes’kov¹, Yu.N. Fedorov², A.I. Albulov², O.V. Bukhantsev², O.A. Bogomolova²

The authors estimated the influence of different doses of Provagen probiotic and its complex with chitosan on immune status of calves. A dose-dependent immunomodulating effect of these preparations was established. The drinking of Provagen in dose of 14 г х head^-1 х day^-1 and the probiotic (14 г х head^-1 х day^-1) with chitosan (0.8 г х head^-1 х day^-1) complex promotes to an increasing of lymphocytes amount in blood and to a rising of humoral immune defense. The duplicated Provagen dose shows the lesser marked stimulatory action on immune system of calves.

Keywords: calves, probiotics, hitozan, immune system, immune responses.
