ENERGY EFFICIENCY OF PRODUCTION OF CATTLE BREEDING PRODUCTS OF MEDIUM-CAPACITY ENTERPRISES WITHIN THE SIMULATION MODEL PARAMETER SYSTEM

The results of monitoring the production and organizational indicators of more than 20 farms are presented with the definition of the main elements that characterize them. The relationship between the degree of technical support or technological equipment of the production process of milk production (quantitative composition of tractors, trucks, machinery, aggregates, milking equipment) and the annual productivity of cows is analyzed. Correlation coefficients indicate its moderate value (0.3<Rxy,<0.5). A simulation model of the production of cattle breeding products in the conditions of enterprises of medium production capacity has been created. Technological elements that are characteristic of the rational process of production of products – milk, beef, live weight of animals in rearing and fattening-are substantiated. Within the technical parameters of enterprises with a number of cattle of 1000-1100 heads (350-450 cows with a capacity of 7000-9000 kg per cow), the annual total energy costs for the production of cattle products are determined. The structure of the energy content of products by type is calculated, namely milk, live weight of culled animals, growth of reared animals, received offspring. The energy content of excrement and bedding is also taken into account. It is established that the largest share in the structure of the energy content of products suitable for nutrition belongs to the energy content of produced milk – 78.9–86.1 %, and since it is the most influential factor on the coefficients of energy efficiency of the main and general products, the functional dependences of the energy content of products on fat in milk and the relationship between the coefficients of energy content of products and milk fat are determined.
