In poultry industry, feed has been considered as the most important component in term of energy and cost which caused a huge burden for small-scale farmers. On the other hand, many industries produce significant number of organic wastes which could be utilize as substitute for poultry feed. In this study, broken kangkung seed (Ipomoea reptans Poir) (KS), a byproduct seed company, and its fermentation product (KSF) were applied as part of rations for quail (Coturnix-coturnix japonica) and the effect on the eggs production and quality were observed. The study was conducted with a completely randomized design method with 4 ration namely R1 (0% KS/KSF), R2 (7,5% KS/KSF), R3 (15% KS/KSF), and R4 (22,5% KS/KSF) and replicated 5 times (each replication consisted of 12 of 30-days old quails).The parameters observed were production performance: daily egg production (%), daily egg mass (grams), egg weight (grams), and egg quality: Haugh unit, shell thickness, shape index, albumen index, yolk index, and yolk color. The results showed KSF meal increased egg production around 37.35%, egg mass 5.94%, egg weight 5.40%, and decreased feed conversion 13.79%. Based on the mean value of each parameter, KS meal had a better effect on the yolk color, yolk index, and shape index while KSF meal increased the albumen index value, shell thickness, and haugh unit.
