The present study aimed to evaluate the effect of the addition of organic selenium on the oxidative stability of pork (Sus scrofa domestica) stored for eight days at 4°C ± 0.5. A group of pigs was given the control diet, without organic selenium, and the other group received the diet with organic selenium (0.3 ppm). At 40 days of organic selenium supplemented, 15 samples of pork randomly were extracted (Longissimus dorsi muscle) from each treatment from a population of 140 pigs, and lipid oxidation was measured by the TBA method and antioxidant capacity by DPPH test days one, four and eight of storage at 4 ° C ± 0.5. In the proximate analysis results were observed significant difference (p<0.05) in the fat content which was lower in organic selenium treatment. An analysis of the fatty acid profile of the samples were made from both treatments where were found significant differences (p<0.05). In the analysis of TBA was observed that lipid oxidation increased with time, showing significant difference (p<0.05) on day eight of storage for type of supplementation. Meat samples from Longissimus dorsi muscle from pigs fed with a diet supplement with organic selenium showed less oxidation than those from treatment without organic selenium. Antioxidant capacity values for DPPH, expressed in terms of TEAC and VCEAC, decreased over time and were higher for treatment with organic selenium than without organic selenium, but without showing significant difference by type of supplementation
