| Research Abstract |
Claw lesions in sows on 3 commercial farms were assessed in 7 areas of each of a sow’s 8 claws to investigate the relationship between claw lesions. In addition, the relationships between claw lesions and postural behavior, reproductive performance or culling risk were investigated. We used a 5-point score method (0, 1, 2, 3 or 4) for each claw area. The highest claw lesion score for each sow was defined as the highest claw lesion score (HCLS) recorded in the 56 claw areas. Of the 308 sows observed, proportions of sows with HCLS 0, 1, 2, 3 and 4 were 0.0, 43.5, 50.6, 4.9 and 1.0%, respectively. No differences were found between HCLS groups for overall culling risk after weaning (P > 0.10). There were no differences between TSLS groups for adjusted 21-day litter weight, preweaning mortality or weaning-to-first-mating interval (P > 0.10). No differences were found between HCLS groups for the sow performance (P > 0.10). There were no differences between HCLS groups for postural behvior (P >0.10). Additionally, Risk factors for claw lesions identified in the present project were latepregnancy and high parity and perpendicular slatted floors.
