Group mean microscopic L. intracellularis lesion score
| Group | Mean lesion score (range: 0–9) | Lesion severity distribution | |||
|---|---|---|---|---|---|
| Normal | Mild | Moderate | Severe | ||
| T01-LAW | 4.3 ± 0.9A | 1 | 3 | 3 | 3 |
| T02-LAW | 3.3 ± 0.7A | 1 | 8 | 0 | 1 |
| T03-LAW | 3.3 ± 0.5A | 1 | 6 | 3 | 0 |
| VAC-LAW | 4.9 ± 1.1A | 1 | 4 | 1 | 4 |
| NEG-CONTROL | 0.0 ± 0.0B | 10 | 0 | 0 | 0 |
| POS-CONTROL | 5.6 ± 0.8A | 2 | 5 | 2 | 11 |
The score is based on a combination of intestinal hyperplasia, inflammation and L. intracellularis antigen and distribution of the pigs in each group into normal (score 0), mild (score 1, 2 or 3), moderate (score 4, 5 or 6) or severe (score 7, 8 or 9).
aDifferent superscripts (A,B) indicate a significant different weight gain (P < 0.05) among groups during a time period.
