Table 6 Intestinal morphometric indices in the piglets in relation to diet and intestinal segment (n = 12, end of the trial)

From: Partially defatted black soldier fly larva meal inclusion in piglet diets: effects on the growth performance, nutrient digestibility, blood profile, gut morphology and histological features

Items Diet (D) Intestinal segment (IS) SEM P-value
BSF0 BSF5 BSF10 Duodenum Jejunum Ileum   D IS D × IS
Vh, mm 0.38 0.36 0.38 0.41a 0.38a 0.34b 0.012 0.371 < 0.001 0.709
Cd, mm 0.11 0.11 0.10 0.12a 0.10b 0.11b 0.003 0.256 0.009 0.999
Vh/Cd 3.47 3.35 3.72 3.64a 3.71a 3.19b 0.126 0.159 0.007 0.566
  1. BSF0 = control; BSF5 = 5% inclusion level 5% inclusion level of black soldier fly meal; BSF10 = 10% inclusion level of black soldier fly meal; Vh, villus height; Cd, crypt depth; Vh/Cd, villus height to crypt depth ratio
  2. The means with different superscript letters (a, b) within the same row per fixed effect (i.e. diet, intestinal segment) differ significantly (P < 0.05)
