1BSFL, 4% DL, and 8% DL represent the three treatment diets containing 4% black soldier fly larvae meal, 4% and 8% Drosophila larvae (days 1–21), respectively.
a–cMeans that rows not sharing the same superscript letter are statistically different (P < 0.05). Data are expressed as mean ± SD (n = 5).
