I had a call this week about an animal that died from bloat on a high clover pasture. Incidence of bloat can increase as the content of clover in pastures gets higher or animals are grazing very lush after-grass type grazing. Bloat occurs when gas pockets occur in the rumen of the animal and cannot escape. Clover swards and leafy pasture are very easy and quick to digest and this increases the chances of bloat occurring. Certain animals tend to be prone to bloat and it is an inheritable trait.
