Ear and flank biting

Why is it measured?

Ear and flank biting behaviour has a similar aetiology to that of tail biting, indicating that the environment is insufficient to meet the behavioural and / or physiological needs of the pig, for example a lack of sufficient manipulable substrate or insufficient space. The presence of lesions is likely to be associated with pain and may additionally provide a route to infection.

How to assess and score using the AssureWel measure

Ear and flank biting (dry sows and finishing pigs)                                                                  Pen measure

Observation:

Record:
 

Assess all animals in pen

If ear biting (EB) lesions are present, and
If flank biting (FB) lesions are present

Typical fight or clambering / mounting lesions show parallel lines, while lesions from flank biting are typically round.
