多组学技术在猪肉质性状研究中的进展OA

China is a major consumer of pork,and improving pork production and meat quality is the key research direction of pig genetic improvement.Pork quality traits are affected by multiple factors such as breed,feeding management,nutrient composition,environmental factors and post-slaughter treatment,and the regulatory mechanism is relatively complex.It is difficult for traditional evaluation methods to fully reveal the underlying genetic mechanisms affecting pork quality changes.With the development of high-throughput sequencing technology,the combination of genomic,transcriptome,proteomic,epigenome,metabolomic and microbiome technologies provides a more comprehensive perspective for in-depth understanding of the formation mechanism and genetic basis of pork quality traits.This paper focuses on reviewing the application progress of omics technology and multi-omics combined methods in pork meat quality traits,and discusses the challenges which the technology faces and its future development prospects,aiming to provide methods for the analysis of the genetic mechanism of meat quality traits and ideas for pig molecular breeding.
