Background and aim: Glucose and insulin are two important factors in regulation of food intake. Also, existence of central glucoreceptors have been determined in human and many of animal species and regarding the similarities of central regulation of food intake in human and chicken, in this study evaluated existence of central glucoreceptors and regulatory role of glucose in ingestive behavior of broiler cockerels Materials and methods: This case-control study performed on 128 Ross 308 broiler cockerels. At the first, guide cannula implanted stereotaxicaly in right lateral ventricle of brains of chickens. At onset of experiments, birds were injected with different doses of glucose and insulin via intracerebroventricular. Then in other experiments, chickens received insulin prior to injection of glucose and cumulative food intake was measured 30, 60, 90, 120, 150 and 180 minute after injections. Data obtained were analysed by SPSS statistical software and One-Way ANOVA. Significant differences imply to P≤0.05. Results: The results of this study showed that glucose and insulin had no effect on food intake in chickens (P≥0.05). Conclusion: It is concluded that central glucoreceptors had no role in start of ingestive behavior in birds.
