Glutathione reductase activity of birds fed 0 (control) or 0.05% methylsulfonylmethane (MSM) with 5% of either fresh or oxidized oil in the diet. Values represents least square means derived from 11 replicates total (4 and 7 reps in cohort 1 and 2 respectively; n = 11) initially containing 12 birds per cage. All birds received their assigned diets from study days 0 to 21.
