Abbreviation: DBSFLM: defatted black soldier fly larvae meal; IBW: initial body weight; FBW: final body weight; WGR: weight gain rate; SGR: specific growth rate; FI: feed intake; FCR: feed conversion ratio; PER: protein efficiency ratio; SR: survival rate; CF: condition factor; VSI: viscerosomatic index; HSI: hepatosomatic index. Data are presented as the (3 for growth performance and for somatic indices). Different superscript letters in the same row indicate statistically different values ().
