Mean (±S.E.M.) body weights for male (solid symbols) and female (open symbols) rats raised on a 20% protein diet (circles) and rats raised on a 6% protein diet (squares) from birth (0 days) to 50 days postnatal. Mean body weights for rats fed the 6% protein diet were significantly less than rats fed the 20% protein diet beginning at birth and extending through P50.
