Comparative Study on Various Growth Performances of Korean Oge and White Leghorn Chickens

Genetic resource conservation of indigenous species is important to conserve terrestrial, aquatic and avian species throughout the world. The native Korean Oge (KO) chickens are important and protected indigenous avian species in Korea. This KO breed is very popular in Korea because of its external appearances of blackish color. The characterization of morphology and growth performances of KO were performed since 1980s, however the information is still not sufficient for breed selection. In this study, we compared various growth performances including body growth, tibia length, shank length, chest width, chest grith and length of tail feather between male and female chickens of KO and widely known White Leghorn (WL) breeds at 1 week, 2 weeks, 5 weeks, 10 weeks, and 24 weeks. We observed differences on various growth performances at different aged groups between KO and WL chickens. This study may help for the selection of chicken breeds based on age, body growth and meat production.
