Effect of Centrally Administered Methionine or Related Compounds on Feeding Behavior in Chicks

Abstract

Bungo, T. and Shiraishi, J. 2010. Effect of centrally administered methionine or related compounds on feeding behavior in chicks. J. Appl. Anim. Res., 38: 197–200.

The effects of intracerebroventricular (ICV) injection of methionine (150–600 mg), and the related compounds, taurine (125–500 mg) or S-adenosyl-L-methionine (1–100 mg) were investigated using neonatal chicks. L-Methionine (600 mg) and D-methionine (300 and 600 mg) significantly increased food consumption at 30 min post injection. Taurine, one of the metabolites of methionine, failed to accelerate feeding behavior in chicks. In addition, S-adenosyl-L-methionine (100 mg), which is synthesized from methionine, tended to depress food intake in ad libitum chicks. These findings indicate the involvement of methionine as a chemical mediator in the regulation of food intake in chicks.
