The article presents data on the digestibility of nutrients when various doses of chromium picolinate are included in the diet of bulls. The second group of animals receiving chromium picolinate at a dose of 1.739 mg/kg of dry matter feed was characterized by better consumption characteristics of crude protein, crude fiber and nitrogen-free extractive fractions, as well as increased digestibility coefficients, which was confirmed by stimulation of protein, carbohydrate and lipid metabolism processes. Mineral metabolism was characterized by an increase in magnesium by 12.5%, phosphorus by 26.4-34.8% with a slight change in calcium (0.7-1.7%). Thus, the dosage of chromium picolinate (1.739 mg/kg of dry matter) is optimal for the nutrients’ metabolism in bulls raised for meat.
