摘要
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.

该研究旨在确定corsbbred韩国本土鸡（CKNC）对孵化生长性能指数的影响为28天。将总共192只1日龄的鸟类分成5个韩国本土纯菌株的4个CKNC组之一。本研究中使用的饮食包括两个阶段，玉米和豆粕基础较早（1~2周;粗蛋白18.5％，代谢能3000千卡/千克），种植者（2~4周;粗蛋白质15.0％，代谢能量2,850千卡/千克）。每两周测量一次体重和采食量。杂交1G（家系组）具有较高的体重和平均日增重，而杂交5Y具有比其他杂交韩国本地鸡孵化至28天更高的平均每日采食量和饲料转化率。目前的研究结果表明，与其他杂交的韩国本土鸡孵化相比，杂交1G具有更高的生长性能指数至28天。
