Appetite is the desire for feed and water and the voluntary intake of feed and is an important regulator of livestock productivity and animal health. Economic traits such as growth rate and muscle development (meat deposition) in broilers are directly correlated to appetite. Factors that may influence appetite include environmental factors, such as stress and temperature variation, and animal‐specific factors, such as learning period, eating capacity and preferences. Feed preferences have been reported to be determined in early life, and this period is important in broilers due to their fast growth and relatively short growth trajectories. This may be of importance when contemplating the use of more circular and sustainable feeds and the optimization of appetite for these feeds. The objective of this review was to review the biological mechanisms underlying appetite using data from human, animal and bird models and to consider the option for modulating appetite particularly as it relates to broiler chickens.

调节肉鸡食欲以改善身体和肌肉发育——综述。

食欲是对饲料和水的渴望以及对饲料的自愿摄入，是牲畜生产力和动物健康的重要调节器。肉鸡的生长速度和肌肉发育（肉沉积）等经济特性与食欲直接相关。可能影响食欲的因素包括环境因素，如压力和温度变化，以及动物特定的因素，如学习期、进食能力和偏好。据报道，饲料偏好是在生命早期确定的，由于肉鸡的快速生长和相对较短的生长轨迹，这一时期对肉鸡很重要。在考虑使用更循环和可持续的饲料以及优化对这些饲料的胃口时，这可能很重要。
