This study was conducted to investigate the performance of crossbreed Korean native ducks for the production of Korean native commercial ducks that are adapted to the Korean environment. A total of four hundred eighty ducklings (1 d old) that were crossbred from the A and B lines (derived from the National Institute of Animal Science) were used in this work and divided into 8 treatment groups (4 replicates/group, 15 birds/replicate) with 4×2 factors (4 groups, i.e., AA, AB, BB, BA and 2 genders, i.e., male and female). The ducks were fed diets based on corn-soybean meal from 0 to 3 wk (22.0% [CP], 2,904 kcal/kg [ME]) and from 3 to 8 wk (18.0% [CP], 3,002 kcal/kg [ME]). The body weight of the AA group was higher than those of the BB and BA groups (P<0.05), but there was no significant difference in body weight at 8 wk of age. The body weight gain in the AB group was the greatest among the groups (P<0.05), but there was no significant difference in body weight gain between the crossbreds from 0-3, 3-8 or 0-8 wk old. Regarding body weight gain, feed intake, and feed conversion ratio, the males exhibited higher values than the females at the ages of 3 and 8 wk old (P<0.05 and P<0.01, respectively). There were no significant differences in uniformity or livability. However, the production index of the males was greater than that of the females (P<0.01). These results may provide the basic data about the growing performance and productivity of crossbreed Korean native ducks for the production of a commercial Korean native duck.
