This study was carried out to investigate the comparison of meat quality of Korean native black porks and modern genotype pork fed high and low lysine levels of diets at growing and finishing stages during refrigerated storage after thawing. M. longissimus from Korean native black pigs (gilts) with a live weight of 65 kg and modern genotype pork (gilts) with a live weight of 110 kg were frozen at -80 ℃ for 1 month and placed in the dark room at 1℃ for 7 days after thawing. The moisture content was significantly lower in modern genotype pork fed high lysine level of diets than to the other treatments (p<0.05), but crude fat content was significantly higher in modern genotype pork fed high lysine level of diets (p<0.05). The pH value and sensory evaluation were significantly higher in Korean native black pork than to modern genotype pork (p<0.05), and the drip loss was significantly lower in Korean native black pork (p<0.05). CIE L*, ho and hunter L were significantly lower in modern genotype pork fed high lysine level of diets than to modern genotype pork fed low lysine level of diets (p<0.05). Myristate, palmitate and saturated fatty acid content were significantly lower in Korean native black pork fed high lysine level of diets than to Korean native black pork fed low lysine level of diet (p<0.05), but unsaturated fatty acid content and UFA/SFA ratio were higher in Korean native black pork fed high lysine level of diets (p<0.05). Consequently, as Korean native black pigs were fed high lysine level of diets at growing and finishing stages, saturated fatty acid content of pork increased but unsaturated fatty acid content and UFA/SFA ratio of pork decreased. And the water-holding capacity, color stability and sensory evaluation of Korean native black porks were better than those of modern genotype pork.
