Effects of lameness on productivity and longevity for sows in pen

Objective: To determine the impact of lameness on sow productivity and longevity evaluate effects housing management removal lame sows in herds using pen gestation. Materials methods: Retrospective production records information methods were collected from 23 farms gestation analyzed for 214,254 2014 through 2020. Statistical analyses performed to differences longevity, productivity, methods. Results: Lameness was third most reported cause study (13.7%). Sows culled spent significantly fewer days herd (P < .001), resulting litters .001). The odds increased by several farm level factors including dynamic groups decreasing square footage .05). Implications: is one top 3 reasons those are costly as they leave earlier, less productive, more likely die or be euthanized versus culled. Housing play a role should further investigated.
