The data on the effect of different dosages of vitamin A (Mikrovita-A) on the metabolism and localization of macroelements of calcium and phosphorus in the body of battened bull calves on diets with pulp pellets are presented. It was found that it is necessary to introduce A-vitamin preparations in such diets so that the vitamin A content in diets is 240 IU per head per day at the beginning of feeding and 230 IU at the end of feeding, which is 20% more than the recommended norms calculated for carotene. This contributes to better calcium and phosphorus nutrition of animals.
