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