The article presents the results of research on the study of the raw milk properties of cows when adding an energy feed additive (ECD) based on activated zeolite to the diets. The work was carried out in the conditions of the MTF "Smak Kors" RT. The results of the study of the qualitative composition of milk-raw cows showed that ECD contributed to an increase in MJ in group I by 0.09 %, in group II-by 0.15 %, in group III-0.22 % (P<0.01) in relation to the control. According to the content of MDB in milk, the difference in the indicator was at the level of 0.04-0.14 %, respectively. The improvement of the quality composition of the raw materials had a positive impact on the cheese suitability. It should be noted that the positive effect increases with an increase in the dose of the test feed additive. The best cheese-making properties were characteristic of the milk of cows of the third experimental group. In them, under the action of rennet, a dense clot was obtained from the milk of 80.0 % and a loose clot was obtained in 20.0 %, and the milk had a short clotting time of 15.3 minutes. The milk of the cows of all experimental groups met the requirements of the desired type II.
