The work presents the results of the study of the chemical composition and the influence of nut kernel cake on digestibility, nutrient exchange and productive performance in breeding young pigs. The results of the investigation showed that nut kernel cake, obtained by cold pressing, has a high nutritional value and contains: 5.51% nitrogen, 344.5 g / kg crude protein, 306.6 g / kg digestible protein, 1.29 nutrient units, 62.69 g / kg crude cellulose, 133.9 g / kg fat, 15.30 Mj / kg metabolizable energy, 0.27% calcium and 0.71% phosphorus, may be accepted for use in the feeding of pigs in a proportion of 4% / t and 8% / t of compound fodder. When using in the pig's feed 4% / t nut kernel cake, an average daily increase of 613g was obtained, with the digestibility of the dry matter 86.8%, the crude protein 79.3%, the crude fat 62.3%, crude cellulose 62.0%, organic matter 88.4%, the cost price of 1kg of combined fodder with 33 bani was reduced, and when using 8% / t these indices were 608 g average daily increase, digestibility of dry matter 85.4%, crude protein 78.5%, crude fat 69.1%, crude cellulose 37.3%, organic matter 87.2%, the cost price of 1kg of compound fodder was reduced by 67 bani.
