The efficiency of different complexes of biologically active substances including various mixtures of dry matter of the chicken gizzard stomach, vitamin B12, vitamins A, D3 and E, iodine-starch and zinc sulfate in various combinations for colostrums-dairy period of suckling calves of 45 days old was established. Dynamics of calves live weight after various combinations of the observed substances was presented. The further dynamics of the calves development up to 6 months old was observed. Research results showed that the preparation complex containing the complex of cuticle, vitamin B, vitamins A, D3 and E, iodine-starch and zinc sulfate was the most effective. Application of the complex of the observed substances was economically effective and increased the production performance, basal metabolism, natural resistance and vital capacity of calves
