1 Four dietary treatments: C = control; TM5 = 5% inclusion level of Tenebrio molitor; TM10 = 10% inclusion level of Tenebrio molitor; TM15 = 15% inclusion level of Tenebrio molitor. 2 Three types: neutral, acidic sialylated and acidic sulfated mucins. 3 Four gut segments: duodenum, jejunum, ileum and cecum. 4 Three fragments: base, midsection and tip. 5 Three gut segments: duodenum, jejunum and ileum. 6 Degrees of freedom. 7 Statistical significance: p < 0.05.
