Identify cause of lameness

Catch and identify

Catch
  • The first lame sheep in a group, even if mildy lame (short stride and nodding / flicking their head) ideally immediately, but definitely within 3 days.
  • Aim to inspect 1/3 flock each day and treat any lame sheep
Identify
  • Make sure you can identify the cause of lameness (see below for common causes), contact your vet for help if in doubt
  • Do NOT trim sheep with scald or footrot or CODD, these can be diagnosed by smell, trimming delays healing
  • Only trim if necessary to diagnose the problem
