We performed two experiments feeding fattening pigs with diets including antioxidant-containing sesame seed (SS) in order to investigate the effects of feeding SS on growth performance and quality of pork. For Experiment 1, diets containing 80% corn were given to six control pigs, while diets containing 3% SS and 77% corn were given to six sesame pigs (from 66kg to 114kg). For Experiment 2, diets containing 40% brown rice and 40% corn were given to six control pigs while diets containing 3% SS, 40% brown rice and 37% corn were given to six sesame pigs (from 64kg to 110kg). There was no difference in growth performance between the SS-fed group and control group in both experiments. On the other hand, feeding SS increased the ratio of linoleic acid (P<0.05) and the amount of gamma-tocopherol in inner subcutaneous fat (P<0.05). Sesame lignans (sesamin and sesamolin) accumulated in inner subcutaneous fat in all sesame-fed pigs (Experiment 1) and barrows of sesame-fed pigs (Experiment 2). We kept slices of these pork loins in cold storage for a week and measured thiobarbituric acid reactive substances (TBARS), however no significant difference was observed. Feeding diets including 3% SS did not suppress the level of lipid oxidation, but changed the ratio of fatty acid and the accumulation level of antioxidants from SS in fat. These effects were also observed by feeding SS with brown rice.
