Our study analyzed the carcass properties of 170 Korean native pigs in relation to carcass weight and back-fat thickness to provide general data for the production and distribution of high quality pig meat. The 70-74 kg group showed highest yield (73.41%). The >= 80 kg group showed the highest thickest back-fat (24.13 mm) (p<0.05). The >= 80 kg group showed the best quality grade (1.00). Back-fat thickness showed significant differences in the weight among groups (p<0.05). The >= 25 mm group showed the highest carcass weight (75.93 kg). The thickest back-fat group (>= 25 mm) showed the highest yield (73.03%). There were significant differences in back-fat thickness among groups (p<0.05), and the >= 25 mm group showed the highest thickness back-fat (27.60 mm). We found a strong positive correlation between carcass weight and back-fat thickness (r=0.346) as well as meat quality grade (r=0.739). Back fat thickness had a relatively strong positive correlation with meat quality grade (r=0.444). Therefore, there are required to manage the breeding through selection of excellent native species for increasing their carcass weight and enhance meat quality.
