Table 4. Stress hormone (corticosterone) and stress index (Heterophil:Lymphocyte ratio) of broilers fed deoxynivalenol and microbial feed additive.
Stress parameters | Control group | DON group | DON + Mycofix group | Mycofix group | P value |
Corticosterone (ng/ml) | 0.52b±0.2 | 1.53a±0.7 | 1.25a±0.4 | 0.54b±0.2 | 0.001 |
Heterophil % | 63b±1 | 69a±2 | 62b±2 | 64b±2 | 0.035 |
Lymphocyte % | 27a±2 | 23b±4 | 27a±1 | 27a±1 | 0.090 |
H/L ratio | 2.39b±0.20 | 3.14a±0.23 | 2.43b±0.15 | 2.40b±162 | 0.034 |
Means within the same row with different superscripts are significantly different (ANOVA followed by Duncan test; n = 10/treatment).
