The effects of dietary curcumin (CUR) on intestinal histomorphometric measures (µm) of O. niloticus.
| Villous Height | Villous Width | Crypt Depth | MT | |
|---|---|---|---|---|
| CUR0 | 868 b | 97 d | 146 d | 162 b |
| CUR200 | 1034 ab | 145 b | 223 b | 131 c |
| CUR400 | 1178 a | 146.50 b | 129 e | 66 d |
| CUR600 | 1203 a | 214 a | 313 a | 164 b |
| CUR800 | 1062 ab | 124 c | 184 c | 198 a |
| SEM | 26.70 | 8.83 | 17.38 | 12.85 |
| Linear Reg. # | ≤0.01 | ≤0.01 | ≤0.01 | ≤0.01 |
| Quadratic Reg. # | ≤0.01 | ≤0.01 | ≤0.01 | ≤0.01 |
# The regressions were considered significant at p < 0.05. Variation in the data was expressed as pooled SEM. a,b,c,d,e Mean values in the same column with different superscripts differ significantly (p < 0.05). MT: muscular layer thickness. CUR0, CUR200, CUR400, CUR600, and CUR800: basal diets supplemented with 0, 200, 400, 600, or 800 mg curcumin/kg diet, respectively.
