Comparisons between the Korean native pig(KNP: 75kg of slaughter weight and 240 days of age) versus Landrace(110kg of slaughter and 180 days of age) in dressing and lean meat percentages, compositions of fatty acids and amino acids and sensory evaluations on longissimus muscle are as below. Compared with Landrace, KNP had smaller percentages in dressing and lean meat percentages and a smaller backfat thickness. In retail cuts, KNP had greater percentages in shoulder butt, belly and picnic shoulder and smaller percentages in spareribs, ham and loin muscle. The KNP had greater percentages in crude fat, palmitic(C16:0) and linolenic(C18:3) acids and smaller percentages in oleic(C18:1) and linoleic(C18:2) acids, but total cholesterol content and ratios of saturated and unsaturated fatty acids and essential fatty acids did not differ between the two breeds. In amino acid composition, KNP had a greater percentage in lysine, but smaller percentages in most other amino acids. The KNP had a greater a*(redness) value in longissimus muscle(LM) color and a greater L*(whiteness) value in attached backfat color. Moreover, sensory evaluations on cooked LM showed that KNP had greater flavor, tenderness and springiness, which resulted in a greater overall acceptability. In summary, KNP, compared with Landrace, had smaller dressing and lean meat percentages, a smaller backfat thickness, greater percentages in popular retail cuts, greater percentages in intramuscular fat and an $\omega$-3 component linolenic acid, with no difference in cholesterol content, which, altogether, is considered to be more beneficial for human health.
