This research explored the utilization of Fermented Kangkong Juice (FKJ) as water additive to enhance the egg quality and production performance of Japanese quails (Coturnix coturnix japonica). The study aimed to minimize costs by replacing synthetic additives with FKJ, derived from fermented upland kangkong leaves. The research encompassed a 60-day experiment conducted in Barangay 25-S Payao, City of Batac, Ilocos Norte, involving 150 five- to six-week-old Japanese quail pullets. The research employed a Randomized Complete Block Design (RCBD) with five treatments, including a control group with pure water, a commercial water additive, and experimental groups with varying levels (30, 40, and 50 ml) of FKJ mixed with 1000 ml of drinking water. Parameters measured included the growth (final weight and gain in weight), morbidity and mortality rates, laying performance (HDEP, feed consumption, and FCR), and external (egg weight, egg mass, and shape index) and internal (yolk color) egg quality including the profitability (net income and ROI) of using FKJ in Japanese quail egg production. Results indicated no significant differences in all measured parameters for the growth, health, egg quality, and laying performance of Japanese quails. However, the highest gross income was observed in T1 (PhP 3,101.00), followed by those in T3 (PhP 3,072.00). The lowest gross return was obtained from T0 amounting to PhP 2,888.00. In conclusion, while FKJ did not yield significant improvements in the studied parameters, it offers potential as a natural supplement. Recommendations include incorporating 30-40 ml of FKJ in a liter of water as a substitute to commercially available water additive or multivitamins. To recover the capital invested in quail production, the researcher suggests continuing in the business until it reaches a point of diminishing returns. To gain higher profit without compromising growth, laying performance and egg quality, Japanese quails can be given with pure drinking water only and Future researchers can consider increasing the levels of FKJ supplemented in the drinking water as well as the increments per treatment.
