We conducted to elucidate the effects of feeding brown rice on characteristics of loin of fattening pigs. To make the brown rice feeding, we replaced feed formulation in the control diet with brown rice: the control diets were purchased feed to fattening pigs in the farm. The three level of brown rice contained in the diet brown rice was 15% (15% group) or 30% (30% group) or 50% (50% group). The pigs were fed diets until their live weight reached 76 kg, thus the period of the trial was 30 days. The growth and carcass grading were same results in the control and three groups. We determined the crude fat and fatty acid composition of loin: the crude fat of loin of the carcasses was higher in the 50% group (p0.05). The more the level of brown rice was high, the more percentage of oleic acid showed a tendency to increase whereas that of linoleic acid showed a tendency to decrease.
