The objective of this study was to study the quality of eggs coming from Isa Brown chickens nourished with fermented dragon fruit peel (Hylozereus polyrhizus) dietary for 4 weeks. The experimental design used was Completely Randomized Design (CRD) with 3 treatments for 5 replications in which each consisted of 10 chickens; so that the total number of chickens was 150 heads aged 85 weeks. The given treatments were R0: feed without fermented dragon fruit peel flour +1% Calcium. Calcium in their diet. Variable observed: egg production, egg weight, exterior and interior eggshell weight, egg thickness, HU. The results showed that treatment of R0, R1, and R2 are not significantly different (P>0.05) for yolk colors, pH, Index but % egg production, egg weight, HU, egg thickness R1 and R2 is significantly different (P>0.05) than R0. Conclude this research that quality of egg Isa Brown gave ration fermentation four skin dragon fruit (Hylocereus polyrhizus) 5% (R1) and with fermentation dragon fruit peel flour + 1% Calcium (R2) increase the egg production, egg weight, HU, egg thickness.
