a-bMeans without a common superscript letter differ (P < 0.05).
Abbreviations: BCFA, branched-chain fatty acid; BSFL, black soldier fly larvae; SCFA, short-chain fatty acid; SEM, standard error of the means.
1
All means are average of 10 replicates per treatment.
2
Experimental diets were produced by adding oils (i.e., corn oil, coconut oil, and black soldier fly larvae oil) into a base diet to reach 50 g/kg of diet.
3
BCFA, (isobutyrate + valerate + isovalerate); SCFA, (acetate + propionate + butyrate + isobutyrate + isovalerate + valerate + lactate).
