This study was carried out to investigate carcass grade of pigs according to gender, feed intake, backfat thickness, carcass weight, etc. Data from a total of 26,983 heads in 5 farms were collected. The results obtained were as follows; The difference was significantly found in carcass quality grade between barrows and gilts (p<0.001). The meat grade 1+ was high in gilts, but meat grade 1 was high in barrows, respectively. The carcass weight of 85.8 kg was lightly shown significantly (p<0.05) in group I taken little quantity of feed consumption. However, that of 89.5 kg was heavily shown in group IV taken plenty of feed consumption. Meat grade 2 was significantly (p<0.001) high ratio in group of backfat thickness with less than 15 mm (67.5%). However, the ratio for the grade 1 was high in group of 15~19 mm. The ratio for the meat grade 2 was highly shown in group of carcass weight with more than 85 kg (54.3%). On the other hand, that of grade 1 was highly shown in group of 78~84 kg. In conclusion, pigs for marketing to enhance high quality have been appropriately raised with the optimum system in consideration of feed intake, carcass weight, backfat thickness, etc.
