An acute lameness, lasting up to 10 days, develops in groups of grower/finisher pigs or selected replacement stock. Detecting sows in the earlier stages of lameness - at which time, they are more likely to respond to treatment - requires a more specific lameness protocol or locomotion scoring system.

Awareness of the problem is the first step in addressing lameness and, because of the implications that culling gilts for lameness has on herd productivity and profitability, the sow herd is the most important place to start. Awareness of lameness in the sow herd has to start with an assessment of reasons for culling sows, and sow replacement and mortality rates. Routine inspections done in the farrowing house will also mean that the lesions can be monitored such that intervention happens early rather than later to prevent lameness occurring.
