Defatted black soldier fly (Hermetia illucens) larvae meal can partially replace fish meal in diets for adult Chinese soft-shelled turtles

Abstract The aim of this study was to analyze the feasibility of partial replacement of fish meal (FM) with defatted black soldier fly larvae meal (BSFLM) in the diet of Chinese soft-shelled turtles by determining the growth performance, serum biochemical indices, antioxidant capacity, proximate composition, and amino acid profile. The turtles were divided into five groups (G1, G2, G3, G4, and G5) and fed with diets in which 0, 5%, 10%, 15%, and 20% FM was replaced with BSFLM, respectively. The growth performances of the turtles in the G2 and G3 groups were the same as those in the G1 group (P > 0.05), whereas the feed conversion ratio of the G3 group was significantly decreased (P
