Fish waste and Indigofera zollingeriana leaves have potential as alternative protein sources for poultry feed. The utilization of these ingredients is expected to reduce dependence on conventional feed materials while improving the rearing efficiency of laying quails. This study aimed to evaluate the effect of feeding a combination of fish waste and Indigofera zollingeriana leaves on the production performance of laying quails (Coturnix coturnix japonica). The experimental birds were 10 weeks old laying quails reared for 6 weeks. A completely randomized design was used with five treatments: A = 0% fish waste and 0% Indigofera zollingeriana leaves, B = 5% fish waste and 5% Indigofera zollingeriana leaves, C = 10% fish waste and 5% Indigofera zollingeriana leaves, D = 5% fish waste and 10% Indigofera zollingeriana leaves and E = 10% fish waste and 10% Indigofera zollingeriana leaves, each with four replications. The results showed that the combination of fish waste and Indigofera zollingeriana leaves had no significant effect (p > 0.05) on the performance of laying quails. The inclusion of fish waste and Indigofera zollingeriana leaves at a ratio of 10%: 10% in the diet of laying quails resulted in a feed intake of 20.90 ± 0.13 g/bird/day, egg production rate of 89.17 ± 0.64%, egg weight of 12.15 ± 0.05 g, feed conversion ratio (FCR) of 1.93 ± 0.02, and yolk color score of 7.50 ± 0.58. These results indicate that the combined inclusion of fish waste and Indigofera zollingeriana leaves at these levels can be effectively used in quail diets without negatively affecting their performance. © 2026 by the authors.
