    The objective of the study was to asses the impact of heat stress (HS) on the digestibility and retention of nutrients in finishing pigs, and the effect of dietary supplementation of heat stressed pigs with antioxidants,(vitamin E, vitamin C,zinc and selenium). The study was arranged into four treatments whereby, first,second and third groups were put under HS and fourth group was in thermo neutral(TN) room. First and fourth (HC and TC) groups were fed on the basal diet as per NRC(2012) recommendations, while second and third (HT1 and HT2) groups were fed on the supplemented basal diets. From the study, there was no significant difference between the HC and TC groups. However, significant differences were observed between groups fed on basal diet (HC and TC) only and those fed on supplemented diets (HT1 and HT2). This findings shows that in this trial, the ambient temperatures did not significantly impact on the pigs digestibility and retention of nutrients, which could be as a result of the pigs high tolerance to HS. However, the study proved that antioxidant supplementation could improve digestibility and retention of nutrients but vitamins and minerals inclusion and supplementation need to be carefully evaluated.
