Rats were given purified or chemically defined diets low in phenylalanine for from 5 to 10 days. L-Phenylalanine supplementation permitted a growth response of 4 g daily with a feed efficiency of 3 (g feed eaten/g weight gained). L-Phenyllactic acid produced a maximum growth rate about one-half of that induced by phenylalanine. The activity of shikimic acid was even lower and was equivalent to one-quarter of the rate with phenyllactic acid.
