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

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

Index	Diet (D)^d				Intestinal segment (IS)^e			SEM		P-value

Vh villus height, Cd crypt depth, Vh/Cd villus height-to-crypt depth ratio
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)
^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
^eThree intestinal segments: DU duodenum, JE jejunum, IL ileum
