Replenishing the deficiency of essential nutrients in the diets of cattle for maintaining the achieved level of cattle productivity and health is a primary task in livestock breeding. The use of rye-based liquid cereal molasses for feeding Kholmogor cow-heifers made it possible to increase the milk productivity of the animals and to improve the quality of milk. The studies were performed at the UR SUE Pikhtovka Rybkhoz, an enterprise in the Votkinsk region of the Udmurt Republic. At the premises of this agroindustrial complex, an UZK-1000 unit developed by ZAO Sharkan RTE was installed for the production of cereal molasses. The comparative analysis of the animals in the experimental groups, where beet molasses were replaced with cereal molasses, clearly showed the effectiveness of using this component in the diet of cows. In the case of using cereal molasses, the milk yield of the cows over 305 days of lactation was 7,702 kg, which was 157 kg higher than in the reference group. Milk quality also improved : the mass fraction of fat increased by 0.17% (3.78%) and the mass fraction of protein increased by 0.07% (3.18%). The profitability level of the animals in the experimental group was 11.5%, which was higher by 6.3% than in the reference group. Thus, the use of cereal molasses in feeding cows had a significant effect on their productivity and milk quality, as well as on the profitability of the product in general.
