to study the effect of dietary methionine on the bioavailability of se from selenomethionine ( [ se ] met ) , weanling rats were first loaded with se by feeding 0.5 mg se as [ se ] met per kg diet of a low methionine ( 0.17 % by analysis ) torula yeast-based diet for 21 d , and then were fed an se-deficient diet ( less than 0.02 mg se/kg ) supplemented with 0 , 0.4 or 0.9 % methionine for 28 d .
