Each value is the mean of 11 replicates (11 birds/treatment).
Means with different letters within each variable differ (p < 0.05).
CON, control diet; 50 BSFLO, 50% black soldier fly larvae oil diet; 100 BSFLO, 100% black soldier fly larvae oil diet; SEM, standard error of the mean; LW, live weight.
