Abstract:

The aim of this study was to explore the mechanism of flavor difference of Angus beef at different months of age based on metabonomics analysis.Angus longissimus dorsi muscle of 17,20 and 24 months old was tested for meat quality traits and metabolomics analysis under the same feeding and management conditions.The metabolome results showed that 69,51 and 53 positive differential metabolites and 53,46 and 58 negative differential metabolites were identified in the B17 vs B20, B17 vs B24 and B20 vs B24 groups,respectively.The expression of 166 differential metabolites was up-regulated and 164 differential metabolites were down-regulated.KEGG enrichment analysis showed that differential metabolites were mainly enriched into multiple metabolic pathways such as lipid metabolism,amino acid metabolism,carbohydrate metabolism and endocrine system,including insulin resistance,cholinergic synapse,linoleic acid metabolism,phosphopentose pathway,carbohydrate digestion and absorption,glucagon signaling and arachidonic acid metabolic pathway.Correlation analysis showed that key metabolites such as proglutathione,betaine,carnitine,choline,hypoxanthine,palmitoleic acid,citric acid and lactose were significantly correlated with phenotypic data and could be used as potential candidate metabolites for Angus beef.Our results indicate that there are significant differences in the quality and flavor of Angus beef at different months of age,and the identified differences in metabolites and metabolic pathways can provide a theoretical basis for future Angus cattle breeding.
