A total of 30 Korean native pigs (gilt 15, boar 15) were used to investigate the carcass characteristics, meat quality, amino acid, and fatty acid composition by gender. The carcass weight of boars were significantly higher than gilts, whereas the carcass yield of gilts had significantly higher than boars (p<0.01). Boars had significantly higher moisture contents in loin muscle than gilts, whereas the protein contents of loin muscle had significantly higher in gilts than boars (p<0.01). In the results of meat quality analysis, the cooking loss (p<0.01), shearing force (p<0.05), lightness (L) and yellowness (b) in meat color (p<0.05) were significantly higher, but the pH was significantly lower (p<0.01) in gilts compared with boars. Arginine (p<0.05), alanine, aspartic acid, histidine, leucine, lysine, phenylalanine, serine, threonine and tyrosin (p<0.01) for gilts were significantly higher than those for boars. The results of fatty acid composition showed that gilts had significantly higher contents of C16:1n7, C18:1n9, C20:1n9 (p<0.01) than boars in intramuscular fat, whereas boars had significantly higher contents of C18:2n6, C20:4n6 (p<0.01) and C18:3n3 (p<0.05) than gilts in intramuscular fat.
