Popis:	The article presents the data of the effect of different doses of pyridoxine hydrochloride on the activity of humoral immunity in the blood serum of calves of the dairy growing period. The lowest activity of the indicators of humoral immunity was found in the serum of calves for the first day of life in all research groups. Exogenous administration of pyridoxine hydrochloride to colostrum and milk led to changes in the studied parameters. It was found that the bactericidal activity of serum increases on the 21st day of calf life and slightly decreases on the 90th day. The addition of pyridoxine hydrochloride at different doses to the milk leads to a probable increase in bactericidal activity of the serum only at doses of 4.0 mg/kg body weight at 60 and 90 days (P
