Injections of mammalian gonadotrophin (1100I.U. of PMS or 2.5mg of FSH) into immature pullets caused no appreciable change in the nature of plasma proteins when tested by the NaCl-Ac turbidity test. In all pullets treated with PMS, significant combs growth and marked yellow pigmentation of the leg were observed after 5th injection, while increased oviduct weight was confined to few pullets which exhibited follicular growth in the ovary at the termination of the injection period.
Pullets treated with FSH showed no change either in the plasma proteins or in the organ weight.
