Establishment of Crossbreed and Comparison of Growing Performance for Commercial Korean Native Duck

Abstract

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