| 摘要: |
| 为了解肉用畜禽（牛、绵羊、猪和家禽等）肌纤维发育特性的最新研究现状，以"畜禽"、"肌纤维发育"和"肉品质"为关键词，对1981-2019年国内外相关研究进行了检索，分别从肌纤维特性、肌纤维生成过程、肌纤维生长发育的分子调控等方面归纳了不同畜禽的肌纤维发育特征。研究发现：不同畜禽肌纤维发育的一般过程基本相似；肌纤维发育的时间具有物种特异性；个别基因被确定具有调控肌纤维发育的主要功能；仍缺乏多物种肌纤维发育过程基因调控网络的构建与系统比较研究以及多物种肉品质鉴定的通用分子标记开发。 |

| Abstract: |
| In order to understand the latest research status of myofiber development characteristics of meat livestock and poultry (cattle,sheep,pigs and poultry),taking "livestock","myofiber development" and "meat quality" as keywords,literatures published in from 1981 to 2019 were searched and summarized from the perspectives of myofiber,myoblast production,molecular regulation of myofiber growth and development.The results showed that the general process of myofiber development in different livestock and poultry are similar;The time of myofiber development among species is different;Individual genes are determined to have the main function of regulating myofiber development.It is also found that there is still a lack of studies on the construction of gene regulatory networks,systematic comparison for multi-species myofiber development and the developing of universal molecular markers for meat quality identification. |
| Key words: meat livestock and poultry myofiber development molecular regulation |
