PERMANOVA illustrating the effect of the type of forage and vitamin E supplementation on the structure of the bacterial and methanogen communities in the Rusitec system.
| Communitya | Bacteria | Methanogens | ||
|---|---|---|---|---|
| Pseudo-F | P-value | Pseudo-F | P-value | |
| Forage | 3.92 | 0.037 | 2.80 | 0.082 |
| Vitamin E | 1.38 | 0.283 | 2.83 | 0.103 |
| Forage × Vitamin E | 1.11 | 0.366 | 0.70 | 0.575 |

Higher Pseudo-F and lower similarities and P-values correspond to greater differences in the microbial composition. Samples were taken at 4 and 24 h after feeding (n = 8).
