Abstract: The work presents the results of studies on the productivity and quality of pig meat by using grape seed flour in the diet. The aim of this work was to study the chemical composition of feed and determination of the effectiveness of the use of grape seed flour in animal feed for fattening young pigs. The experiment was conducted on 33 pigs, having the same level of development, constitution and health, distributed in three lots (control and two experimental) of 11 heads. The selection of animals was carried in the lots-analog taking into account the breed, origin, age, live
weight, and growth rate during the preparatory period. The best results in average daily gain for the experiment (719 g), payment of feed (3.41 kg), serum amylase content at the end of the experiment (71.60 mmol/l), well-developed ham with an average weight of (11.06 kg), area muscle eye (42.7) cm², the protein content in meat (20.16%), fat (1.77%) as well as the economic effect per head for the period of the experiment (136, lei 14 bani) were obtained from hybrid pigs that received grape seed flour in the feed composition 6% of the main diet. The introduction of 4% grape seed flour into the feed composition helped to reduce the cost of 1 kg of mixed fodder per 10 bani, and when it was introduced 6% – by 19 bani. We believe that the use of grape seed flour in feed for pigs is one of the ways to increase productivity, feed conversion, as well as reduce the cost of feed.
