A scientific and practical substantiation of the need for the timely formation of colostral immunity in calves to create nonspecific protection of the body and adaptation of newborns to new environmental conditions is given, which is the most important problem of modern veterinary science and practice. Colostral immunity is immunity that develops in newborns due to colostral immunoglobulins during the first 24-36 hours of life. For some newborn farm animals (horses, ruminants and pigs), antibodies are transmitted to offspring only through colostrum in the early postnatal period. In order to increase the nonspecific defenses of the body of mothers cows, the formation of colostral immunity in newborn calves and the realization of the biological resource potential of the body, immunostimulants were used, developed by scientists of the Chuvash State Agrarian University: Prevention-N-B-S and Salus-PE.
