<br/><br/> The study was conducted from November 6 to December 20, 2023 in <br/>Barangay Magnuang, City of Batac, Ilocos Norte, to evaluate the growth <br/>performance, health status, laying performance, egg quality, and profitability of <br/>Japanese quails fed different levels of black soldier fly larvae meal (BSFLM). A total <br/>of 180 ready-to-lay quails were randomly and equally distributed into four dietary <br/>treatment groups with three replications following a Randomized Complete Block <br/>Design (RCBD). The treatments were: (T1) 100% pure commercial feed (CF), (T2) <br/>95% CF + 5% BSFLM, (T3) 90% CF + 10% BSFLM, and (T4) 85% CF + 15% <br/>BSFLM. Analysis was done using the analysis of variance (ANOVA) for RCBD and <br/>treatment means were compared using Least Significant Difference Test using STAR <br/>V.2.0.1. <br/>The results showed that quails fed with BSFLM showed no significant <br/>differences in terms of growth performance, health status, laying performance, egg <br/>quality (except egg width), and profitability. Furthermore, there were no negative <br/>health effects or mortalities associated with the inclusion of BSFLM. Moreover, a <br/>positive net income was obtained from all the treatments, resulting in positive return <br/>of investment. The highest ROI was obtained from quails fed with pure commercial <br/>feeds. The treatment with the highest inclusion rate of BSFLM gave the lowest ROI.
