The paper presents an innovative view of the recommended feeding rations for effective milk production on an industrial basis in the conditions of southern Ukraine, taking into account the fact that this territory belongs to the zone of risky land use and the negative effect of global warming, which has been manifested in recent years. Scientific and economic experiments were carried out at the State Enterprise “SF Andriyivske” of the Bilhorod-Dnistrovsky district of the Odesa oblast according to generally accepted methods. The advantages of using winter rye as a crop whose growing season falls on wetter periods of the year have been established, which makes it possible to harvest high-quality silage with an energy content of 12.0 MJ, crude protein 12.7%, neutral detergent fiber 51.9% in the calculation per 1 kg of dry matter. A tendency to advantage in terms of milk yield was established from the cows of the experimental groups that received rye silage in combination with wet beer groats as the main fodder. Taking into account the ratio of fat and protein in the milk of the cows of the experimental groups in our studies, the optimal ratio of fat: protein was established in the cows of IV experimental group (1.2: 1), whose rations as the main forage contained only 45.0 kg of rye silage with the addition to this 6.0 kg of wet beer grain. The use of rye silage in combination with wet beer groats in the feeding rations of the cows of the experimental groups revealed a positive effect on indicators of rumen fullness, manure consistency, feed digestion, cow fattening, health status, reproductive capacity and animal survival. A tendency was established for the superiority of the milk yield of the cows of the experimental groups for 305 days of lactation by 95-258 l, respectively, compared to the animals of the control group, where the milk yield was 7,898 l, which, due to the use of cheaper ingredients in the rations, made it possible to reduce the cost of production of 1 liter of milk by 11.3-23.7%.
