The development of animal production is a priority because it provides the most important food resources from the nutrition point of view for the entire population, and the demographic explosion and rise of living standard have led to the increased demand for food of animal origin. The profitability of pig growth is influenced by their rational feeding. It is known that food production expenses have the largest share in food production, varying between 60 and 80% of the total of these expenditure. As a result, particular attention should be paid to the maximum efficiency of compound feed in order to make it transformed in human food products with an as high as possible percentage. To achieve this goal, the nutrients from the ratio should be correlated with the physiological requirements of the animals. For this purpose, in this paper was analyzed the influence of maize, barley and peas hybrids on the apparent digestibility of nutrients from the compound feeds for pregnant sows, lactating sows and piglets during weaning. The preparation of recipes for mixed feeds requires a good understanding of the basic principles of nutrition and how diet should be individualized based on age, gender, physiological status. The apparent digestibility of the analyzed organic substances (crude protein, crude fat, crude fiber) from the compound feed recipes was influenced by the chemical composition of the compound feeds used, especially the crude fiber content, as well as the swine physiological state.
