The influence of different levels of chromium in the diets of black-and-white heifers on the energy of their growth was studied. It was established that the optimization of this element in their diets increases the difference in live weight by the end of the period of their cultivation. So, at 27 months of age, heifers of the first group increased their live weight by 4.1 kg (p <0.05) and 2.0 kg, which is 0.8% and 0.4% more than peers from the second and the third group receiving a reduced and increased dosage of chromium
