This experiment aimed to investigate the potential impact of supplementing different levels of black soldier fly (BSF) on growth performance, serum antioxidants, and ruminal microbiota of goats. Twenty-four native Anglo-Thai male goats (18.43± 0.76 kg) were distributed across 4 dietary treatments with 6 repetitions in each group. The control treatment (BSF0) did not include BSF, the other treatments (BSF5, BSF10, and BSF15) contained 5%, 10%, and 15% of BSF, respectively. Black soldier fly supplementation did not affect ( P > 0.05) growth performance. With increasing supplementation levels, the digestibility of dry matter (DM) decreased linearly and quadratically ( P < 0.05), while organic matter (OM) decreased linearly and quadratically ( P < 0.05). The apparent digestibility of crude protein (CP) decreased linearly ( P < 0.001), and neutral detergent fiber (NDF) and acid detergent fiber (ADF) decreased linearly and quadratically ( P < 0.05). Serum malondialdehyde concentration showed a linear ( P < 0.05) response at 0 h, while superoxide dismutase activity and 2,2-diphenyl-1-trinitrophenylhydrazine (DPPH) concentration exhibited linear responses ( P < 0.05) at 4 h. Black soldier fly supplementation did not affect ( P > 0.05) ruminal pH. In the BSF15 group, ruminal ammonia nitrogen (NH 3 -N) concentration decreased quadratically ( P < 0.001) at 0 h, and linearly ( P < 0.05) at 2 and 4 h. Acetic acid decreased linearly ( P < 0.05) at 2 and 4 h, propionic acid decreased linear...
