Abstract

Rising feed costs and environmental concerns associated with conventional poultry feeds necessitate the exploration of sustainable alternatives. Black soldier fly larvae (BSFL) meal has emerged as a promising substitute due to its high protein content and potential for waste reduction. This study assessed the growth performance, profitability, and financial feasibility of broiler feeds incorporating BSFL meal, compared to traditional soybean meal-based diets. A total of 108 one-day-old Ross 308 broilers were randomly assigned to three dietary groups ( n = 36; 12 birds per replicate): (i) T0 (Control, 29% soybean in starter, 19.5% soybean in grower), (ii) T1 (20% BSFL inclusion), and (iii) T2 (25% BSFL inclusion). Birds were raised for five weeks. Broilers fed the 25% BSFL diet exhibited significantly ( p < 0.05) higher final body weight (1887 g) and total weight gain (1846 g) compared to the control group (1777 g and 1734 g, respectively). Feed intake was highest ( p < 0.05) in the 25% inclusion group (3384 g), exceeding the 20% BSFL group (3257 g). Feed conversion ratio (FCR) improved significantly ( p < 0.05) with 25% BSFL inclusion (1.83) when compared to control (1.90). Economic analysis showed that benefit-cost ratio (BCR) increased from 1.16 (control) to 1.28 (20% BSFL) and reached 1.36 with 25% BSFL ( p < 0.05). Financial feasibility analysis, based on local prices in Dhaka, Bangladesh, further revealed that 25% BSFL inclusion achieved the highest NPV of USD 326.14 and IRR of 47.7%, indicating superior profitability. These results confirm BSFL meal as a sustainable, and profitable protein source for broiler production.
