This is a relatively common disease affecting adult cows in this country. It has many names, also being called foreign body reticulitis, reticuloperitonitis and reticulopericarditis depending on the exact presenting signs.In all cases, the affected animal has eaten a foreign body, invariably a piece of wire, which has become embedded in the wall of the cow’s reticulum (second stomach). The outcome depends on whether the wire is released from the wall or progresses to fully penetrate the wall of the stomach.
