Effects of Dietary Corticosterone on Yolk Colors and Eggshell Quality in Laying Hens Yeon-Hwa Kim1,2, Jimin Kim1,2,3, Hyung-Sook Yoon1,2, and Yang-Ho Choi2,3,* 1 Division of Applied Life Sciences (BK21 Plus program), Gyeongsang National University, Jinju 660-701, Korea ABSTRACT: The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly. Egg weights and egg quality were measured daily. Corticosterone treatment resulted in a remarkable increase in feed intake and sharp decrease in egg production compared with control (p
