The objective of this study was to evaluate the influence of supplemental dietary selenium (Se) and magnesium (Mg) on feedlot lambs. Sixty-four male lambs were randomly distributed to the following treatments: 1) low level of Mg and Se: diet with 0.18% of Mg and 0.1 μg Se/g, 2) with supplementation of magnesium oxide (MgO): diet with 0.32% of Mg and 0.1 μg Se/g, 3) with supplementation of Sodium selenite (Na 2SeO 3): diet with 0.3 μg Se/g and 0.18 % of Mg, 4) With supplementation of MgO and Na 2SeO 3: diet with 0.32% of Mg and 0.3 μg Se/g. There were no differences ( P>0.05) in the average daily gain and feed conversion but Se supplement with Na 2SeO 3 (0.3 μg Se/g) enhanced dry matter intake, dressing percentage ( P<0.05) and leg muscle weight ( P<0.02). The average values of the water retained potential, coordinate L, a, and sensory analysis were different with Se ( P<0.05). Magnesium suplemented as inorganic source (0.32% of Mg) enhanced ( P<0.05) some characteristics in sensorial meat analysis.
