Cattle Parasitic Disease and Welfare

Parasitic diseases including lungworm, liver fluke, and gut worms cause significant welfare harm in cattle requiring strategic management.

Key Facts

Lungworm (husk) causes severe respiratory distress and can cause outbreaks in naive adult cattle
Liver fluke causes liver damage, anemia, and death in heavily infested cattle
Ostertagia ostertagi causes type II ostertagiasis with severe protein loss in housed cattle
Integrated parasite management combining targeted treatment and monitoring reduces resistance risk
Pasture management and housing strategies reduce infective larval contamination

Welfare Considerations

Parasitic disease causes extensive hidden suffering in cattle through respiratory distress, liver damage, and chronic protein loss. Strategic parasite management prevents the welfare compromise of established disease and protects the effectiveness of treatments for future use.

What You Can Do

Support farms using diagnostic monitoring to guide parasite treatment decisions
Advocate for integrated parasite management standards in cattle welfare certification
Choose beef and dairy from farms demonstrating sustainable parasite control programs
