Abstract: The effects of Intra Cerebro Ventricular (ICV) injections of various glutamatergic receptor agonists were investigated using broiler chicks. ICV treatments with N-methyl-D-aspartate (NMDA: a selective agonist of NMDA-subtype of glutamatergic ionotropic receptors) stimulated feeding behavior of chicks in a dose-dependent manner. On the other hand, ICV administration of kainate (a selective agonist of kainate-subtype of glutamatergic ionotropic receptors), AMPA (a selective agonist of AMPA-subtype of glutamatergic ionotropic receptors) or ACPD (a metabotropic glutamate agonist) did not affect feed intake in meat-type chicks. These findings indicated the involvement of glutamate as a chemical mediator in the regulation of feeding behavior in the meat-type chick, possibly acting on the central nervous system in this line through NMDA-sensitive glutamatergic receptor.
