Abstract
The Jeju native pigs of 168 heads (116 barrows and 52 gilts) were examined to investigate the carcass characteristics related to gender, meat quality grades and yield grades. The averages of carcass characteristics for Jeju native pigs were 72.94 kg for carcass weight, 20.98 mm for backfat thickness, 38.14 for Hunter L*, 4.68 for a*, 6.04 for b*, 5.61 for pH, 3.61 for visual plate meat color, 3.36 for marbling scores, 1.83 for meat quality grades and 2.08 for yield grades, respectively. The carcass weight of gilts was significantly higher than that of barrows (p<0.05). There were no significant differences between barrows and gilts in carcass percent, backfat thickness, and meat color. The pH of barrows was significantly higher than that of gilts (p<0.05). The differences between gender groups were significantly noticed in carcass quality grades, and yield grades (p<0.05). The carcass weight, carcass percent, backfat thickness, and marbling scores for pigs with high grades(1 and 2 grades) were significantly higher than those for pigs with low grades (p<0.05). However, there was no significant difference among 4 carcass grades. The carcass weight, carcass percent, backfat thickness, pH, and meat color for carcass with high yield grades were significantly higher than those for carcass with low grades (p<0.05). The meat colors for Hunter L*, a* and b* were not significantly shown in carcass yield grades.
