摘要:

喙是鸟类上下颌包被的硬角质鞘,起到哺乳动物唇和齿的作用。喙畸形是近年来在鸟类发现并逐渐受到重视的一类骨骼疾病。喙畸形在家禽尤其是我国一些地方鸡品种中常见发生,主要表现为上下喙交错,咬合不全,呈交叉状态,严重影响个体饮水和采食,造成生长缓慢甚至死亡,给家禽生产造成巨大的经济损失,同时也威胁动物福利。目前,国内外关于鸡喙的起源、形态结构、生长发育等方面的研究相对较少,鸡喙畸形的形成机制尚不明确,而在鸟类,尤其是达尔文雀喙畸形的研究取得了较大的进展。本文综述了鸟类(包括鸡)喙的起源、形态结构、生长发育、影响因素以及其他物种唇部形态变化等相关研究,以期为人们开展鸡喙形态发育及喙畸形的分子机制研究提供借鉴。

Abstract:

Beak is an external anatomical structure of birds.Its functions are the same as lips and teeth of mammals.Beak deformity,a new skeletal disease,was first reported in birds and gained more and more attention recently.Beak deformity(normally a crossed beak) has also been found in some indigenous chicken breeds in China.The chicken with a deformed beak has problems in eating and drinking,which could cause slow growth and early death.This causes economics loss and is harmful to the animal welfare.Until now,the origin,morphosis,growth and development of beak has less been studied.The mechanism of beak deformity in chickens is not clear yet.The study of beak deformity in Darwin’s finches has a greater progress.This article summarized these related studies in birds,aiming to provide guidance for the study of beak development and molecular mechanism of beak deformity in chickens.
