title: Possible growth factors for chickens in silkworm pupae meal.
abstract: Silkworm pupae were included in the diet of growing chickens, causing little effect at 50 g/kg but a marked depression in performance at 100 g/kg. Direct comparisons of diets containing silkworm pupae of different ages indicated a growth stimulating effect correlated with ecdysteroid activity.
