This study was conducted to evaluate the productivity of Korean native chicken (KNC) 2 strains crossbred. The number of chicks analyzed in this study was 300. Crossbreds used in this studywere A) KNC R strains × KNC meat type S strains, B) KNC egg-meat D strains × KNC meat type H strains, C) KNC egg-meat D strains × KNC meat type S strains, D) KNC egg-meat C strains × KNC native Y strains, and E) KNC native Y strains × KNC meat type H strains. The crossbreds C had the highest performance on body weight gains at 7~10 weeks but crossbreds D showed the lowest (p0.05). The feed conversion ratio of crossbreds D was the highest value at every weeks (p0.05). But the carcass weight and carcass ratio of crossbreds D was the lowest value at every weeks (p0.05). For the percentage of cutted meat, the ranges of mean were 30.60~33.75% in breast, 21.48~24.72% in leg, 11.95~14.33% in wing, 21.91~25.83% in back and of 7.38~8.72% in neck. The percentage of cutted meat for leg was the highest value at every weeks (p0.05). These results suggested that the development of new crossbreds should be necessary for better performance.
