摘  要:运输应激是肉鸡宰前主要的应激之一。在运输应激条件下,肉鸡机体能量代谢加强,供能物质如葡萄糖、糖原等通过糖酵解作用补充能量,导致宰后肌肉中糖原、乳酸含量及糖酵解关键酶活性发生变化。同时,运输应激影响了肉鸡宰后肌肉能量代谢,进而影响肉品质。本文就运输应激对肉鸡宰后肌肉能量代谢和肉品质的影响进行了综述,并结合宰后肌肉糖酵解及能量代谢信号通路,阐明了运输应激对肉品质影响的调控机制,以期为家禽运输应激研究及能量调控提供参考。Transport stress is one of the main stress of broilers before slaughter.Under the condition of transport stress,the body energy metabolism of broilers is strengthened,and energy were supplied through glycolysis sourced from energy substance such as glucose and glycogen,followed by the changes in the contents of glycogen,lactic acid and the activities of key enzymes in post-slaughter muscle.Meanwhile,transport stress affected post-slaughter muscle energy metabolism of broilers,and then affected the meat quality.This paper reviewed the transport stress affected post-slaughter muscle energy metabolism and meat quality of broilers,and further elucidated the regulatory mechanism of transport stress on meat quality through post-slaughter muscle glycolysis and energy metabolism signaling pathways,in order to provide reference for the study of poultry transportation stress and energy regulation.
