Liver Fluke in Cattle: Welfare Impacts and Integrated Control

Liver fluke disease causes significant welfare impacts in cattle through liver damage, weight loss, and anaemia, requiring integrated control combining treatment and management.

Key Facts

Fasciola hepatica infection is widespread in cattle on wet pastures across Europe and globally
Acute fluke disease from massive larval challenge can cause sudden death in young stock
Chronic fluke disease causes progressive weight loss, bottle jaw, and anaemia over months
The mud snail Galba truncatula intermediate host requires wet conditions to survive
Triclabendazole treats all fluke stages but resistance is emerging in some regions

Welfare Considerations

Cattle with chronic liver fluke infection suffer progressive welfare deterioration through protein loss from damaged bile ducts, anaemia, and impaired liver function. Bottle jaw from hypoproteinaemia is a sign of advanced disease causing discomfort and nutritional compromise. Acute fluke disease in young cattle causes severe liver damage and rapid death. The welfare cost is compounded by immunosuppression that increases susceptibility to other infections. Early detection through faecal egg counting or blood testing enables prompt treatment.

What You Can Do

Test cattle faeces for fluke eggs in autumn and winter on wet pastures
Implement strategic fluke treatment programmes based on disease risk and local resistance patterns
Avoid overstocking wet pastures that increase mud snail habitat and infection risk
Improve drainage on high-risk fields to reduce snail habitat
Rotate flukicide classes with your vet to manage emerging triclabendazole resistance
