Traumatic Reticulitis in Cattle: A Review of 60 Fatal Cases

Abstract

Sixty fatal cases of traumatic reticulitis in cattle were reviewed. Fifty-nine cases were caused by fragments of wire. A nail perforated the reticulum of 1 animal. Common clinical signs included decreased milk production, anorexia, fever, and weight loss. Abnormal or muffled heart sounds associated with pericarditis and epicarditis was the most common sequela, occurring in 40 cases. Fibrous adhesions found at necropsy in all cases suggest that initial clinical signs are difficult to recognize and in most cases it takes weeks to months for abnormalities to be observed.
