An experiment involving twenty-five cross bread barrows(60kg) was conducted to evaluated the effect of medium chain tryglycerides (MCT) or soybean oil addition to finishing diet. Growth performance, carcass characteristics and adipose fat properties of pigs fed a control diet (TDN 71%, DCP 11.3%) were compared with those of pigs consuming diet that contained 4 or 8% levels MCT or soy-bean oil. Pigs fed the diets containing MCT or soybean oil tended to lower feed intake and higher daily gain than control. Feed conversion ratio were significantly superior for the the diets containing MCT or soybean oil. Pigs fed the diets containing 8% of MCT or 8% of soybean oil tended to have thicker back fat. The brightness and melting point of adipose fat were lower when pigs fed the soy-bean oil containing diets and higher when pigs fed the MCT containing diets. These responses were more evident as the MCT or soybean oil containing rate increased
