Abstract: 【Objective】 The effects of Hermetia illucens larvae meal (HILM) as dietary protein source on performance, antioxidant capacity and intestinal health of Sichuan White geese were studied to explore the application of HILM in the diet of Sichuan White geese.【Method】 A total of 180 1-day-old Sichuan White geese (half male and half female) with similar body weight were randomly divided into 3 groups, including control group, miscellaneous meal group and 15% HILM group.Each group consisted of 6 replicates with 10 animals per replicate.During the experiment, food and water were eaten and drank freely, and the feed intake was weighed weekly in the unit of repetitions.The feed intake was recorded, and the average daily feed intake (ADFI), average daily gain (ADG) and feed to gain ratio (F/G) were calculated for each group.Serum antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were detected at 4 weeks of age.The tissue morphology of duodenum, jejunum and ileum was observed by section.The villus height and crypt depth of each intestinal segment were measured, and the villus height/crypt depth was calculated.Real-time fluorescence quantitative PCR was used to analyze the expression of intestinal compact linking protein gene.【Result】 Compared with the control group, in 15% HILM group, the ADFI and ADG of Sichuan White geese were increased (P<0.05), the serum GSH-Px concentration was significantly increased (P<0.05), and the villus height of duodenum, jejunum and ileum was increased (P<0.05 or P<0.01), the crypt depth of duodenum and ileum was decreased (P<0.01), and the villus height/crypt depth of duodenum and ileum was increased (P<0.01).At the same time, the expression of Occludin gene in jejunal tissue in 15% HILM group was increased (P<0.05).Compared with miscellaneous meal group, in 15% HILM group, the serum SOD activity was increased (P<0.05), the crypt depth of duodenum was decreased (P<0.01), and the villus height/crypt depth of duodenum and ileum were increased (P<0.01 or P<0.05).【Conclusion】 As a dietary protein source, HILM could enhance serum antioxidant capacity of Sichuan White geese, improve the intestinal health and absorption function of goslings, and thus improve the production performance.
