SUMMARY

Broiler chickens eat more feed and grow faster than layer chickens. However, hyperphagia-induced excessive accumulation of body fat in broiler chickens has become a serious problem in the modern poultry industry. Species specificity in terms of the physiological role of appetite-regulating hormones and neuropeptides can make it difficult to understand the mechanisms underlying the central regulation of food intake in chickens. Therefore, although the appetite regulatory system of chickens has been a focus of research in recent decades, the mechanisms underlying the hyperphagia of broiler chickens are not fully understood. Our previous studies demonstrated that peripheral hormones significantly suppress food intake in chicks. These findings suggest that postprandial elevation of peripheral anorexigenic hormones plays important roles in appetite regulation in chickens. This review provides an overview of recent findings on the role of peripheral hormones in the regulation of food intake in chickens and proposes the new insight of avian-species-specific system of peripheral regulation of food intake and promising strategies for reducing body fat mass in broiler chickens.

概括

肉鸡比蛋鸡吃更多的饲料并且生长更快。然而，过度进食导致肉鸡体内脂肪过度积累已成为现代家禽业的一个严重问题。就食欲调节激素和神经肽的生理作用而言，物种特异性可能使人们难以理解鸡摄食的中央调节机制。因此，尽管鸡的食欲调节系统是近几十年来研究的重点，但肉鸡过度摄食的机制尚未完全了解。我们之前的研究表明，外周激素显着抑制了雏鸡的食物摄入。这些发现表明餐后外周性厌食激素的升高在鸡的食欲调节中起重要作用。这篇综述概述了最近关于外周激素在鸡摄食调节中的作用的研究结果，并提出了禽类特异性外周摄食调节系统的新见解，以及减少肉鸡体脂肪量的有希望的策略。鸡。
