Abstract

The study was conducted to determine the effect of corssbred Korean native chickens (CKNC) on growth performance indices for hatch to 28 days. A total of 192 1-day-old birds were divided into one of 4 CKNC groups by 5 Korean native pure strains. Diets used in the study consisted of 2 phases with corn and soybean meal basis as earlier (1~2 weeks; crude protein 18.5%, metabolizable energy 3,000 kcal/kg), and grower (2~4 weeks; crude protein 15.0%, Metabolizable Energy 2,850 kcal/kg). Body weight and feed intake were measured bi-weekly. Crossbred 1G (group of family line) had higher body weight and average daily gain whereas crossbred 5Y had greater average daily feed intake and feed conversion ratio than other crossbred Korean native chicken for hatch to 28 days. The results in the current study indicated that crossbred 1G had higher growth performance indices compared with other crossbred Korean native chicken for hatch to 28 days.
