Purpose. To study the effectiveness of the use of feed mixtures for pigs, which include native cereals and products of processing of soybeans and sunflower and their impact on fattening and meat qualities of pigs. Methods. Use, comparison, zootechnical and biometric analysis. Results. The results of the use of feed mixtures, which include native grain of cereals and products of soybean and sunflower processing, and their influence on fattening and meat qualities of pigs are given. It was found that the use in the diets of pigs of experimental groups with soybean meal in the amount of 14.2% and expanded soybean in the amount of 14.8% in the structure of the diet, provides an average daily gain of animals, in general, for the entire fattening period, within 694 and 684 g, which is higher, respectively, by 29 and 19 g compared to the control group, which was fed with sunflower meal in the amount of 17%. At the same time, feed costs per 1 kg of the weight gain were 3.45 and 3.53 feed units, which is less by 0.61 and 0.53 feed units compared to control. According to the results of control slaughter, the best animals were those that consumed soybean meal and expanded soybeans. The difference in terms of slaughter yield (72.1± 0.48 and 71.5± 0.24 %) was 2.1-1.5% respectively. The results of the tasting evaluation of meat and broth show that the best overall qualities of meat samples had the animals fed with soybean products, with average scores of 4.7 and 4.8 points. The highest overall score of the meat broth was obtained by the samples of broth of the IV experimental group of the pigs (5.0 points), the composition of which included expanded soybeans. Conclusions. The results of the research proved high efficiency of soybean products (defatted soybean meal and full-fat soybean deep hydrothermal treatment) in feeding pigs, which help to increase animal productivity and product quality and reduce feed costs per 1 kg of weight gain.
