The objective was to assess meat quality of Brahman×Thai native (BRA) and Charolais×Thai native (CHA) crossbred bulls. In total 34 BRA and 34 CHA under practical farm conditions were randomly assigned for slaughter at 500, 550 and 600kg live weight, respectively. Longissimus dorsi muscle was taken for meat quality and sensory evaluations. CHA meat had higher intramuscular fat, exhibited higher marbling scores and relatively better colour than BRA meat. Although muscle fiber area was similar for both genotypes, shear force values were higher for CHA meat. Water holding capacity was better for CHA meat shown by lower 7-day ageing, thawing and grilling losses. However, the sensory evaluation ratings were similar for both genotypes. Increasing slaughter weight from 500kg up to 600kg had no significant effect on meat quality. In conclusion, meat quality of CHA was superior to BRA.
