<jats:p>According to the data of Samara Veterinary Laboratory, in serum of cattle in 40.7 % of studied samples the calcium indicators have low values while increasing the level of inorganic phosphorus by 18.2 %, which indicates a significant prevalence and severe form of nutritional osteodystrophy in animals of the examined farms. The therapeutic use of a protein-mineral additive based on yeast autolysate, fodder bentonite, mono calcium phosphate and chalk in the general complex of therapeutic measures for alimentary osteodystrophy of lactating cows stimulates mineral metabolism, normalizing the calcium-phosphorus ratio, and has a positive effect on the milk productivity, increasing milk yield by 41.9 %. The preparation helps to stimulate hemoand erythropoiesis and has an anti-toxic effect on liver. The use of the additive allows increasing the economic efficiency of milk productivity during alimentary osteodystrophy of cows by 11.2 %.</jats:p>
