Objective: Black soldier fly (BSF) as an animal protein feed source is currently becoming a hot research topic. This study investigated the effects of the BSF as a protein feed source for goats on slaughter performance, muscle nutrient composition, amino acids, fatty acids, minerals, and antioxidant levels. Methods: Thirty Qianbei Ma goats (20.30±1.09 kg) were randomly divided into three groups: the control group (GRP_C) supplemented with 10% full-fat soybean, treatment 1 (GRP_U) supplemented with 10% untreated BSF, and treatment 2 (GRP_T) supplemented with 10% heat-treated BSF. One-way analysis of variance among groups (with Fisher's least significant difference post hoc comparison) was used in this study. Results: The nutrients, amino acids, fatty acids, minerals, and antioxidants in muscle were analyzed. The results showed that there were no significant differences in the moisture, dry matter, crude protein, ash, amino acids, and mineral content of the muscles among the three feeding groups. The slaughter rate and carcass weight of the GRP_U and GRP_T groups were significantly lower (p<0.05). The overall meat quality of the GRP_U and GRP_T groups decreased (p<0.05). The individual unsaturated fatty acids and total unsaturated fatty acids in the GRP_U group were higher (p<0.05) than those in the GRP_C and GRP_T groups. Both GRP_U and GRP_T decreased (p<0.05) the antioxidant capacity of the meat. Conclusion: Therefore, the heat-treated BSF had a better effect on meat quality compared to untreated BSF, but there were greater negative effects on the meat quality of GRP_U and GRP_T than GRP_C.
