Severity grading score | SH (sole haemorrhage) | SU (sole ulcers) | WL (white line disease) |
---|---|---|---|
Discoloration of the sole horn | Exposure of fresh or necrotic corium | Lesion localised to the white line region | |
0 | No lesion | No lesion | No lesion |
1 | Light pink lesion < 2 cm diameter or diffuse discoloration of sole |  < 2 cm diameter lesion covered by a thin layer of horn prior to modelling | Haemorrhage of the white line, discoloration or separation of the white line which disappears after limited trimming |
2 | Light pink lesion ≥ 2 cm diameter or dark pink/purple lesion < 2 cm diameter |  ≥ 2 cm diameter lesion with < 1.5 cm granulation tissue protruding through the horn | Deeper separation or discoloration of the white line, lesion is still present after limited trimming |
3 | Dark pink/purple lesion ≥ 2 cm diameter or discoloration with blue tinge |  ≥ 1.5 cm granulation tissue protruding through the horn or secondary bacterial infection | Separation of the white line which extends to the corium, purulent exudate or necrotic tissue may be present |
