Intracerebroventricular injection of mammalian motilin, melanin-concentrating hormone or galanin does not stimulate food intake in neonatal chicks

1. Several neural peptides are known to stimulate feeding behaviour in mamm alian species. The aim of this study was to elucidate whether central injec tion of mammalian motilin, melanin-concentrating hormone (MCH) or galanin s timulates feeding in the neonatal chick. 2. None of the peptides applied here enhanced the food intake of the chick. 3. It is suggested that motilin, MCH and galanin, at least those of mammali an origin, may not regulate feeding in neonatal chicks, when administered t o the central nervous system.
