To enrich the diet of black and white cattle with energy and nutrition, we conserved alfalfa haylage with pure cultures of propionibacteria, selected optimal doses of spray material to achieve the maximum conserving effect, and evaluated the effect on interior and productive indicators. The line of research was chosen due to the fact that alfalfa haylage is a high-protein, but difficult to conserve food. To do this, all animals were divided into 4 groups. There were selected control groups fed by haylage without conservatives and experimental groups fed by haylage conserved with propionibacteria. It was found out that in the blood of experimental groups’ animals, the proportion of erythrocytes and hemoglobin increased within the regulatory limits, regardless of the season of the year. The analysis of the weighing data of bull calves revealed a steady increase in the growth of those fed by conserved haylage. By the age of 18 months the weight of experimental group bull calves reached 515.2 – 523.0 kg, which is 15.5 – 23.3 kg higher than the control group (3.10-4.66%). A similar pattern has been established when analyzing the milk yield in black-and-white cows. The productivity of experimental groups’ animals was 2793.6–2918.5 kg for 120 days of lactation and of control groups’ animals was 2678.3 kg. The maximum effect was obtained in the second experimental group, where both young and adult animals got haylage with a conservative intake rate of 4 liters per 1 ton of weight.
