We investigated the effects of dietary supplements of probiotics, illite, active carbon and hardwood vinegar on growth performance, carcass characteristics and fatty acid composition in finishing pigs. One hundred fifty pigs (; average initial body weight) were used in a 100 day experiment. Pigs were randomly placed into five experimental feeding groups (control, 0.2% probiotics, 1.0% illite, 1.0% active carbon and 1.0% hardwood vinegar) and were slaughtered at approximately 110 kg live weight. There was a slight, but insignificant increase in average daily body weight gain and feed intake among all treatment groups. Feed conversion was reduced when probiotics were added (p<0.05). There were no significant differences in the carcass rate and back fat thickness among the all treatment groups including controls. However, the frequency rate of grade A increased in the groups fed 1.0% active carbon and hard- wood vinegar compared to controls. Stearic acid content was lower in the groups fed probiotics illite active carbon and hardwood vinegar (p<0.05). Oleic acid contents were higher only in the groups fed 1.0% active carbon and hardwood vinegar (p<0.05).
