Abstract
Bungo, T., Yoshinaga, S. and Ueda, H. 2002. Intracerebroventricularly administered excitatory amino acids: effects on feeding behavior in chicks. J. Appl. Anim. Res., 22: 161–168.
The effects of intracerebroventricular (ICV) injection of monosodium L-glutamate (MSG) and monosodium L-aspartate (MSA) were investigated using.broiler and layer type chicks. These represent relatively fast- and slow- growing birds, respectively. We found that MSG stimulated food intake of both types of chicks in a dose-related fashion at 30 min post-injection. After 60 min post-injection, this tendency continued in layer chicks, but it disappeared in broiler chicks. On the other hand, ICV administration of MSA did not affect feeding behavior of both types of chicks during the 2h experimental period. Further studies have been recommended to arrive at a definite conclusion.
