Middle Ear Infections
The condition is sporadic but common particularly in the weaned pig and sow and occurs occasionally in the sucking pig from 7 to 10 days of age. If treatment is prompt there is usually a good response. If treatment is delayed there is the risk that infection will spread from the middle ear into the inner ear and inwards to cause meningitis
- The pig stands with its head to one side often shaking.
- As the disease progresses there is a gradual loss of co-ordination until ultimately the pig walks around in a circle eventually falling over.

- Nervous signs i.e. fits, convulsions and meningitis may result.
- Unusual in young piglets.
