Effect of heat stress and RSV on the morphology of jejunum of 42-day-old broilers (d 14 of heat treatment).
| Dietary treatments | SEM | P -values | ||||||
|---|---|---|---|---|---|---|---|---|
| NT | NT + RSV | HT | HT + RSV | P-RSV | P-stress | P-RSV × stress | ||
| Villus height, μm | 1,039.17 | 1,080.25 | 994.48 | 1,090.73 | 28.800 | 0.268 | 0.779 | 0.651 |
| Crypt depth, μm | 161.46 | 157.90 | 188.41 | 156.94 | 5.648 | 0.077 | 0.222 | 0.077 |

Data are presented as mean ± SEM, n = 6. Values in the same row with different superscript are significantly different by one-way ANOVA. P-values (P-RSV, P-Stress, or P-RSV × Stress) ≤ 0.05 indicates RSV, heat stress, or the interaction between heat stress and RSV. RSV, resveratrol; V/C, Villus length/Crypt depth; NT, normal temperature; HT, heat stress.
