In this study, the effects of feeding citrus byproducts on nutritional components of Korean native chickens were investigated. Two samples of Korean native chickens were used for this study: T0 (chickens fed with only feed for laying hen until they became 39 weeks old, not with citrus byproducts) and T1 (chickens fed with citrus byproducts). The feed for T1 was the same as T0 for the first 16 weeks, and then was made by adding 4% of citrus byproducts to the feed for T0 between 17～39 weeks. The chicken used for the experiment was obtained by chilling them for 2 days after slaughter. There was no significant difference between T0 and T1 regardless of feeding citrus byproducts, in terms of their breast/thigh’s calorie, contents of moisture, protein, fat and ash, total structural amino acid, total free amino acid and composition of saturated/unsaturated fatty acids. The breast’s cholesterol amount of T0 and T1 were 48.4 ㎎/100 g and 47.6 ㎎/100 g, respectively, while that of thigh for T0 and T1 were 75.7 ㎎/100 g and 72.8 ㎎/100 g, respectively, which implies that T1 showed lower amount of cholesterol than T0. T1 showed significantly higher amount of phosphorus, potassium, magnesium and vitamin B2 for thigh than T0 (p＜0.05).
