Abstract: This article presents the results of the impact of the use of dry corn meal on feed consumption, growth performance and carcass quality of young pigs subjected to fattening. The aim of the research was the development of effective nutritional solutions for the substitution of classic protein resources with new local protein resources, and the experimental testing of new fodder recipes intended for pig hybrids, with the inclusion of dry corn meal. The results of the analysis of the chemical composition showed that the dry corn meal contains: nutritional units -1.04; metabolizable energy -12.52 Mdj; crude protein - 26.62%; crude fat - 21.95%; raw cellulose -11.69%; non-nitrogenous extractive substances 46.23%; calcium - 0.05%; phosphorus 0.27% in the absolute dry substance, has an increased sugar content of -3.03% and can be accepted for use in the feeding of fattening pigs as an additional protein source.The results of the experiment demonstrated that the substitution of sunflower cake and soybean meal with dry corn meal in different proportions did not essentially influence the appetite and intake of combined fodder during the actual experimental period, and the average daily consumption of combined fodder had average values of 3.153 kg and 3.168 kg corresponding to the batches. When using in the feed of meat hybrids of dry corn in proportions of 6%/ in the first period and 10%/t in the second fattening period, the cost price of 1kg of combined fodder decreased by 14 and 27 bani, an average daily gain of 821g was obtained, the animals produced good carcasses with an average slaughter yield of 80.08%, a 5.46% thinner layer of bacon was obtained in the abdomen, muscle eye surface was 44.11 cm², the average weight of the ham 10.863 kg, the amount of fat in the muscle Dorsal longus of 0.92%, the muscle tissue in the carcasses constituted 60.3%. The economic effect from the use of dry corn meal in the feed of meat hybrids was 274.5 lei/head.Investigations have shown that, due to the organoleptic qualities and the rich content of natural proteins, fats and mineral substances, dry corn meal can represent a viable partial replacement solution for some classic protein sources (sunflower cake, soybean meal) from the feed of young pigs subjected to fattening
