Endocarditis in Cattle: Welfare and Clinical Management

Welfare guide to bovine endocarditis -- a painful cardiac infection causing chronic illness in cattle.

Key Facts

Endocarditis (infection of heart valves) causes chronic pain and progressive heart failure in affected cattle
It typically follows bacteraemia from another infection site such as a foot abscess or respiratory tract
Affected cattle show weight loss, exercise intolerance, fever, and heart murmur
The tricuspid valve is most commonly affected in cattle
Diagnosis requires auscultation and echocardiography -- often delayed due to non-specific early signs
Long-term antibiotic treatment is required but prognosis is guarded
Welfare monitoring should focus on pain, mobility, and body condition
Humane euthanasia is often the most welfare-protective option in advanced cases

Welfare Significance

Bovine endocarditis causes prolonged suffering from cardiac dysfunction and systemic infection. Early detection and aggressive treatment offer the best welfare outcomes, but many cases are not identified until advanced. A low threshold for euthanasia in cases with poor prognosis is the most welfare-protective approach.

What You Can Do

Monitor cattle with previous bacteraemia events for signs of cardiac disease
Seek prompt veterinary assessment for any cattle with unexplained weight loss and fever
Discuss prognosis honestly with your vet -- humane euthanasia is often kinder than prolonged treatment
Prevent predisposing infections through good foot health and housing management
