Use of biologically active additives in feeding young animals is the most important element of resource-saving technologies. The aim of the study was to study the effectiveness of use of vitamin and mineral nutrition on the growth and development of young animals. 3 groups of calves were formed at the age of 10 days. Animals of the control group received the basic diet (OR), the II-experimental group received OR + salts of microelements and the calves of the III-experimental group received OR + salts of microelements and tetratwit in doses from 1 to 3 months – 1.5 mg, from 3 to 5 months – 2.0 mg and from 5 to 6 months – 3.0 mg. Tetravit was injected once every 2 weeks throughout the study. It was found that feeding the salts of microelements (copper, zinc, cobalt, manganese, iodine) to calves during the dairy period contributes to their more intensive development and growth of their meat productivity, both in combination with tetravite and without it. Use of salts of microelements separately, and in combination with a multivitamin preparation (tetravit) contributes to a significant increase in the studied hematological parameters in young animals, relative to control analogues.
