Based on the conducted experiment on the study of energy supplements “Cow Energy” and “Ketostop El” feeding in the diets of lactating cows, their positive effect on the digestibility and accessibility of calcium and phosphorus was noted. Cows of the control group were fed with a multicomponent diet (silage, haylage, grain mix, molasses). The animals of the experimental groups were added energy supplements: I experimental - “Cow Energy” 200 g per head per day, II experimental - “Ketostop El” 200 g per head per day. Cows from the II experimental group were ahead of the control group by 0.40% and 0.38% in the use of calcium and phosphorus for milk, and the I experimental group - by 0.04% and 0.67%. The biochemical analysis of the blood of the experimental cows showed that during the physiological experiment, there were no significant differences in the metabolic processes in the animals. The biochemical parameters of the blood corresponded to the norms of physiological values.
