==History and Clinical Signs==
A typical history would be a recently calved cow with a sudden drop in appetite and milk production. Animals display general malaise and abdominal pain. On clinical exam a rapid loss of condition may be evident, [[Ketosis of Cattle|ketosis]] or decreased ruminal activity on ausculatation. Often the left ribs appear 'sprung', with a concave left paralumbar fossa, and the temperature may be normal or raised.
