| Comparisons between batches | Risk Estimate1 |
|---|---|
| B-0 versus B-06 | 0.927 (± 0.186)a |
| B-0 versus B-12 | 19.78 (± 323.87) |

1Risk estimate coefficient of TB infection (± SE) between batches in farms 1, 2, 3 and 5, determined by a generalized mixed-effect model with post hoc Tukey comparisons between batches. a P = 0.0001, bP < 0.0001.
