Abstract:

Skeletal muscle is the main component of the animal body. The development process of muscle fiber in skeletal muscle is lengthy and regulated by various factors. Genes involved in the muscle fiber development in livestock and poultry have relatively complex regulatory mechanisms, and these genes are also regulated by other factors. The relevant regulators may not be sufficient in livestock and poultry, so exogenous substances need to be added to promote muscle fiber development. By integrating research literature on muscle fiber development both domestically and internationally in the past 5 years, combined with the characteristics of genes related to muscle fiber development, this paper introduces the exogenous substances that affect the development of muscle fiber in livestock and poultry, emphasizes the regulatory effects of these exogenous substances on muscle fiber development, and prospects the research on the regulation of genes related to muscle fiber development, in hoping to provide references for future study.

Key words: exogenous substance, muscle fiber development, gene, signaling pathway
