Gut hormones act as appetite regulatory hormones in mammals. For example, the hunger hormone ghrelin, which is released from the stomach before food intake, stimulates appetite. In contrast, satiety hormones such as cholecystokinin, glucagon-like peptide-1, and peptide YY, which are released from the intestines after food intake, suppress appetite. The effects of these peptides on food intake have been shown to be similar in both mammals and fishes. However, evidence suggests that the physiological roles of these gut hormones may be different between birds and other vertebrates. This review summarizes the current information on the roles of gut hormones in the regulation of food intake in birds, especially in chickens.
肠道激素在哺乳动物中作为食欲调节激素发挥作用。例如，饥饿激素胃饥饿素在进食前从胃中释放，会刺激食欲。相反，饱腹感激素如胆囊收缩素、胰高血糖素样肽 -1 和肽YY，在进食后从肠道释放，会抑制食欲。这些肽对食物摄入的影响在哺乳动物和鱼类中已显示出相似性。然而，有证据表明这些肠道激素的生理作用在鸟类和其他脊椎动物之间可能有所不同。这篇综述总结了关于肠道激素在鸟类，尤其是鸡的食物摄入调节中作用的当前信息。
