Popis: We have examined milk samples from lactating rats fed a low protein (6% casein) diet and a normal protein (25% casein) diet. Total protein content of the milk was reduced. More detailed examination of the milks by two dimensional SDS polyacrylamide electrophoresis indicated that selected proteins are present in different amounts, rather than an overall, across-the-board reduction. Activity of sulfhydryl oxidase was substantially reduced, whereas activity of γ-glutamyltranspeptidase, another membrane-bound skim milk enzyme, was not. These results suggest that the quality of milk is influenced by the maternal diet.
