Table 4 Intestinal morphometric indices in the ducks in relation to diet and intestinal segment (n = 12, end of the trial)

From: Nutritional effects of the dietary inclusion of partially defatted Hermetia illucens larva meal in Muscovy duck

Index Diet (D)d Intestinal segment (IS)e SEM P-value
HI0 HI3 HI6 HI9 DU JE IL D IS D IS D × IS
Vh, mm 1.55 1.51 1.52 1.63 2.12a 1.41b 1.14c 0.06 0.06 0.442 < 0.001 0.508

  1. Vh villus height, Cd crypt depth, Vh/Cd villus height-to-crypt depth ratio
  2. The means with different superscript letters (a, b, c) within the same row per fixed effect (i.e. diet, intestinal segment) differ significantly (P < 0.05)
  3. dFour dietary treatments: HI0 = control; HI3 = 3% inclusion level of Hermetia illucens; HI6 = 6% inclusion level of Hermetia illucens; HI9 = 9% inclusion level of Hermetia illucens
  4. eThree intestinal segments: DU duodenum, JE jejunum, IL ileum
