^aThree dietary treatments: C = control; HI5 = 5% inclusion level of Hermetia illucens; HI10 = 10% inclusion level of Hermetia illucens
^bThree types: neutral, acidic sialylated and acidic sulfated mucins
^cThree gut segments: duodenum, jejunum and ileum
^dDegrees of freedom
^fStatistical significance: P < 0.05
