This study was carried out to investigate the carcass characteristics of crossbred pigs according to mating system, carcass grade and age at marketing. A total of 656 pigs of 128 gilts and 528 barrows were collected and analyzed at public slaughter house. Differences between LY and LYD crossbred on marbling score and water holding capacity were significantly(p<0.05) found. The influences of LY and LYD crossbred on carcass weight, backfat thickness, meat colour, carcass grade and age at marketing were not significantly showed. The carcass weight of D carcass grade was significantly(p<0.05) heavier than that of the other grade. The backfat thickness was significantly(p<0.05) appeared gradually in accordance with the increase of carcass grade. There was significantly difference among the carcass grades on water holding capacity(p<0.05). The differences among the carcass grades on the meat colour, marbling score and age at marketing were not found significantly. The carcass weight of high age group at marketing was significantly heavier than that of the low age group(p<0.05). The backfat thickness of the group of high age at marketing was significantly thicker than that of the group of low age(p<0.05). There were significant differences among age group at marketing in marbling score, carcass grade, and water holding capacity, respectively(p<0.05). The carcass weight was positively correlated with the backfat thickness but negatively correlated with the carcass grade. The correlation between the backfat and carcass grade was significantly negative. The meat colour was negatively correlated with water holding capacity.
