Pig locomotion scoring system to assess lameness (Paula et al., 2024).
| SCORES | DESCRIPTION |
|---|---|
| 0 | No signs of lameness. The animal moves easily, showing full comfort of movement. |
| 1 | Initial signs of lameness in one leg can be seen. The animal is reluctant to bear weight but continues to move without much difficulty. |
| 2 | Lameness involves one or more legs. The animal exhibits compensatory behavior such as dipping of the head or arching of the back. |
| 3 | The animal shows considerable reluctance to walk or bear weight on its limbs. Moving the animal around the farm is difficult. |
