PSXIII-B-1 Black Soldier fly Larvae Were More Digestible Than Adult Flies, and Nutrient Disappearance in Black Soldier fly Larvae can be Predicted Using Acid Detergent Fiber Based on in Vitro Assays for Pigs

Abstract The objectives were to evaluate the nutrient utilization of fish meal, black soldier fly (BSF, Hermetia illucens) larvae, and adult BSF meal develop equations for estimating in vitro disappearance larvae pigs. Two-step 3-step procedures used simulate digestion absorption nutrients gastrointestinal tract In Exp. 1, defatted larva had less (P < 0.05) ileal (IVID) dry matter (DM; 81.2% vs. 91.6% 61.6%) crude protein (CP; 81.8% 92.2% 67.2%) total (IVTTD) DM (82.6% 93.6% 65.7%) organic (OM; 78.1% 91.5% 63.2%) than greater values BSF. 2, CP concentrations negatively correlated with ether extract (r = −0.91) but positively acid detergent fiber (ADF; r 0.98) chitin 0.95). Acid IVID −0.98 −0.88) −0.87 −0.84) IVTTD −1.00 −0.94) OM −0.99 −0.98). Equations using ADF (% DM) as an independent variable developed: CP, % −0.95×ADF + 95 (r2 0.75 P 0.058) OM, −2.60×ADF 115 0.98 0.01). conclusion, was compared flies can be predicted variable.
