ABSTRACT We examined differences in slaughter performance and meat quality of Honghe yellow cattle of different ages. We randomly selected nine Honghe bulls for slaughter at 12 (12M), 36 (36M), and 60 (60M) months of age. There were significant differences in antemortem live weight, carcass weight, and net weight among the three groups, all of which increased with age. Backfat thickness in 36M (4.77±0.25 mm) and 60M (5.50±0.50 mm) was significantly higher than in 12M (3.00±0.00 mm), and the loin-eye […]
