The present study aimed to examine the utility of soybean hull as a feedstuff for fattening pigs. The data of physical characteristics of loin and blood lipid from three pigs fed formula feed as a control group and three pigs fed soybean hull as an experiment group were compared in this study. The experiment group feed was prepared by mixing of soybean hull and formula feed in a ratio of 1:9. There was no significant difference between the control and experiment groups in meat quality. In the fatty acid composition of inner and outer layers of back fat, the ratio of C18:0 significantly (P<0.05) increased, and the ratio of C18:2 in both layers significantly (P<0.05) decreased in the experiment group while the ratio of C18:3 also significantly (P<0.05) decreased in inner layer. There was no significant difference in the results of blood lipid analysis. The present results revealed that feeding fattening pigs with soybean hull had no negative effect on the character of the products. Soybean hull can therefore be used as feedstuff for fattening pigs.
