Methods of cattle diet based on nutritional value of feed components

Purpose. Development of an economic-mathematical model and calculation of the optimal ration of feeding high-performance cows in the stall period, taking into account the capacity of energy, protein and dry matter. Methods. Methods of mathematical statistics and linear programming, higher mathematics, and probability theory were used. Results. A mathematical model has been developed to determine the required number of components of a diet, which makes it possible to calculate the diet in accordance with recent studies, taking into account the number of components available in the farm. Conclusions. Ensuring nutrient balance for cattle ensures the proper functioning of animals, with a normal distribution of energy between the costs of animal activity, development and milk production. Therefore, to ensure a life balance when drawing up the diet, attention should be paid to the dry matter, protein, lactation energy and the content of neutral detergent fiber.
