摘　　要：随着集约化养禽业的蓬勃发展,家禽羽毛发育出现一系列问题,如发育迟缓、蓬乱、异常脱落或干枯无光泽等,甚至导致成年家禽出现裸躯病,引起同伴相互啄食,降低了其活体外观及屠体品质,给养殖企业带来了巨大经济损失。本文综述了家禽羽毛的类型、毛囊的基本结构、毛囊的发生发育与再生以及影响羽毛生长发育的分子信号调控网络,旨在为家禽羽毛的生长发育调控及其商品性状的改善提供理论参考。With the intensification of poultry production, there has been a series of problems arise during the development of poultry feathers, such as developmental retardation, rough feathers, abnormal losing of feath-ers ,and dry feathers. The feather problem has a negative influence on the appearance of their living bodies and the quality of their carcasses, causing considerable economic losses. Here we described the types of fowl feath-ers ,the basic structure of follicles, the development and regeneration of feathers, and the roles of specific mo-lecular pathway that influence the growth of feather. This review aimed to provide a theoretical reference for the regulation of feather quality and the improvement of the commercial characteristics of poultry.
