The aim of the research is to develop a computer model that makes it possible to predict the productivity of pigs based on the data on their consumption of the exchange energy of feed and the amount of feed loss during storage and operation of technological equipment. Based on the known results, regression relationships have been established between the value of the exchange energy of the given feed and the average daily gain in the live weight of animals, as well as the cost of feed per kilogram of gain. Due to the loss of feed nutrients and the feed itself during the storage of feed in warehouses, during preparation and delivery to animals, as well as throwing away part of the feed when it is eaten by animals, the amount of nutrients consumed by the animal and the accounting of feed consumption do not match.
