A comparative study of the central effects of melanocortin peptides on food intake in broiler and layer chicks

► Alpha-MSH suppressed food intake in broiler and layer chicks. ► Beta-MSH suppressed food intake in layer chicks. ► Beta-MSH did not influence food intake in broiler chicks. ► Gamma-MSH did not influence food intake in either strain. ► The absence of β-MSH effect is related to the hyperphagia in broiler chicks.
