Meat tenderness could be associated with fatty acids metabolism in Nellore cattle

Abstract Text: Beef cattle is an important segment of the global economy. Aggregate value to the meat is desirable for red meat sector, but it requires the improvement of meat quality. Tenderness is the main organoleptic characteristic desired by consumers and the molecular mechanisms involved with this characteristic are still unknown. Bos indicus breeds present a different tenderness profile than Bos taurus. The objective of this study was identifying differentially expressed genes between Nellore steers with extreme EBV values for shear force. The genes ADRB2 and CPT1B presented differentially expressed between extreme groups. These genes are associated with fatty acid metabolism, which could be involved with meat tenderness.
