Novel method for facilitating egg-laying recuperation of hen in the course of moulting is provided which comprises administrating LH-RH through intramuscular injection to hen under moulting as well as an aqueous preparation therefor; LH-RH being a substance belonging to decapeptide stimulating secretion of hormone capable of forming corpus luteum.
