In the work are presented the results of research on the study of the productivity and quality of carcasses of pigs when using in the diet the grape seed flour. The best results for the payment of feed (3,94 units), the average daily gain for the experiment 716 g, the protein content in meat 19,78%, fat 1,82%, the area of the muscular eye 41,8 cm2, well-developed hams with an average weight of 10.96 kg, as well as an economic effect per head for the period of the experiment (154, lei 04 bani) were obtained from pigs which received as a part of the compound feed grape seed flour in the amount of 4% of the main diet. The introduction into the composition of mixed fodders 4% of grape seed flour contributed to a decrease in the cost of 1 kg of mixed fodder by 10 bani, and when was introduced 6% - by 19 bani. We believe that this ingredient adds biological value to the obtained products because it acts as a very powerful natural antioxidant, and its use in food represents a nutritional perspective for swine growth.
