Abstract
This work was conducted to evaluate the hatching and growing performance of Korean Native Ducks (KND) Pure Breeding Line (PL). A total of 400 male and female pullets were produced from PL to keep in National Institute of Animal Science, Korea. Pullets were divided into 4 treatments, 5 repetitions per treatment, and 20 heads per repetition. Four treatments were compared in a $2{\times}2$ factorial arrangement with 2 groups (White strains, WW; Jade Green strains, CC) for their parents and 2 groups (male and female). Livability was not significantly different at 20 weeks among male and female of 2 strains. There was no significant difference on body weight and feed intake between WW and CC strains (P>0.05), but there was significantly different on body weight and feed intake between male and female (P<0.05). The feed conversion ratio of female was higher compared to male (P<0.05), but there was no significantly different between CC and WW strains. These results provide the basic data to develope the new strains of Korean Native Ducks.
