This work was carried out to investigate the performance of growing period of two-way crossed of Korean native chickens parental stocks. A total of four hundred eighty female 2-crossbred chicks were used in this study and they were from National Institute of Animal Science. Groups were four crossbreds (4 replications/crossbred, 30 birds/ replication) as A) C strain × Y strain, B) C strain × L strain, C) C strain × G strain and D) C strain × W strain. Body weight of A crossbred was the highest at the age of 8 week (P less than 0.05) and that of D strain was the lowest for growing period (P less than 0.05). Body weights of A and B crossbreds were higher than those of C and D crossbreds at the 12 and 16 weeks (P less than 0.05). Weekly body weights of A and B crossbreds were higher than C and D crossbreds (P less than 0.05), and weekly body weight of B crossbred was higher compared to other crossbreds at 0~20 weeks old. Weekly feed intake of D crossbred was the lowest among all crossbreds at 0~12, 0~16 and 0~20 weeks old (P less than 0.05). Weekly feed conversion ratio of C crossbred was the highest among crossbreds (P less than 0.05). These results can give the basic information for growth related data in 2-way crossbreed Korean Native Chickens, which can be used for the parental stocks for the laying-type of Korean native commercial chickens.
