1 BW, body weight; average body weight of birds selected for slaughter; 2 levels of full-fat Hermetia illucens (HI) larvae meal: HI0—0%, HI50—50%, HI75—75%, HI100—100%; 3 SEM, standard error of the mean; 4 muscles (combined leg and breast muscles); a–d mean values within a row (dietary treatment) not followed by a common superscript are significantly different at p < 0.05.
