Evaluation serum levels of fluorescein isothiocyanate dextran (FITC-d), superoxide dismutase (SOD), gamma interferon (IFN-γ), and IgA in broiler chickens consuming a diet supplemented with 37-ppm Lippia origanoides essential oils on a necrotic enteritis challenge model *.
| Item | Negative Control | Positive Control * | Lippia origanoides * | Pooled SEM | p-Value |
|---|---|---|---|---|---|
| FITC-D (ng/mL) | 80.00 c | 540.00 a | 407.02 b | 49.32 | 0.0001 |
| SOD (U/mL) | 8.85 c | 10.28 b | 14.73 a | 8.56 | 0.0002 |
| IFN-γ (pg/mL) | 78.10 c | 281.4 a | 161.55 b | 24.23 | 0.0002 |
| IgA (ng/mL) | 11.95 b | 17.45 a | 10.45 c | 45.10 | 0.0001 |
* Day-old broilers were challenged with Salmonella typhimurium (day 1), E. maxima (day 18), and Clostridium perfringens (days 22 and 23). a,b,c Non-matching superscripts within rows indicates significant difference at p < 0.05.
