摘要: One important element impacting meat quality is fat metabolism, which mainly affects meat features through intramuscular fat deposition. Chinese native yellow-feathered broilers and white-feathered broilers differ significantly in intramuscular fat concentration. This study used transcriptomic and metabolomic sequencing technologies to identify a total of 173 differentially expressed genes and 259 differential metabolites in the pectoral muscles of Chahua Chicken No. 2 and Cobb broiler in order to explore the genetic mechanisms by which lipid metabolism influences meat quality in Chinese indigenous yellow-feathered and white-feathered broilers. These included differentially expressed genes like FABP1, LPL, ELOVL7, SLC27A1, MOGAT1, and ULK2, which were enriched in pathways relevant to lipid metabolism and showed strong associations with gamma-linolenic acid and palmitaldehyde, two distinct metabolites. In order to develop local chicken germplasm resources and breed superior indigenous chicken varieties, these candidate genes could serve as the genetic foundation for the variations in meat quality and lipid metabolism between Chinese native yellow-feathered and white-feathered broilers.
