This study was carried out to investigate the growth performance and the carcass ratio of meat-type Korean Native Ducks. Four hundred twenty Korean Native Ducks' chicks were selected and divided into four treatments (7 replications/treatment, 15 birds/replication) by strains (A and B) and gender(male and female) with 2×2 fractal factors. There was no significant difference between A and B on the body weight at 2, 4, 6, and 8 weeks old (P greater than 0.05). However, body weight of female was higher at 2 weeks old than male while that of male was higher at the 8 weeks old (P less than 0.01). Daily feed intake of male was higher compared to female during 6~8 weeks (P less than 0.05). On weekly body weight gain, there was no significant difference between strains, but gained body weight of male was higher until 2 weeks old while that of female was higher during 6~8 weeks (P less than 0.01). On the live body weight and carcass weight by strains and genders, B strain was higher than A strains at the 8 weeks of age (P less than 0.01). Carcass yield was the highest at 8 weeks of age in both strains (P less than 0.05). These results may provided the basic data on growth performance and carcass ratio of meat-type Korean Native Ducks.
