Abstract：
In recent decades, a lot of research has been conducted to explore poultry feeding behavior. However, up to now, the processes behind poultry feeding behavior remain poorly understood. The review generalizes modern expertise about the hormonal regulation of feeding behavior in chickens, focusing on signaling pathways mediated by insulin, leptin, and ghrelin and regulatory pathways with a cross-reference to mammals. This overview also summarizes state-of-the-art research devoted to hypothalamic neuropeptides that control feed intake and are prime candidates for predictors of feeding efficiency. Comparative analysis of the signaling pathways that mediate the feed intake regulation allowed us to conclude that there are major differences in the processes by which hormones influence specific neuropeptides and their contrasting roles in feed intake control between two vertebrate clades.
摘要：
近几十年来,已经进行了许多研究来探索家禽的饲养行为。然而,到现在为止,家禽喂养行为背后的过程仍然知之甚少。该评论概括了有关鸡的饲养行为的激素调节的现代专业知识，关注胰岛素介导的信号通路，瘦素,和ghrelin和调节途径与哺乳动物交叉参考。本概述还总结了致力于控制饲料摄入量的下丘脑神经肽的最新研究，并且是预测饲料效率的主要候选者。对介导采食调节的信号通路的比较分析使我们得出结论，激素影响特定神经肽的过程存在重大差异，并且它们在两个脊椎动物进化枝之间在采食控制中的作用不同。
