Sheep Scab and Mange Welfare

Sheep scab caused by Psoroptes ovis mites causes intense pruritus and welfare harm in affected flocks, requiring treatment and biosecurity control.

Key Facts

Sheep scab is a notifiable disease in Great Britain requiring compulsory treatment
Pruritus from mite infestation leads to self-trauma, fleece loss and weight loss
Injectable macrocyclic lactones are the primary treatment approach
Shared grazing and bought-in stock are primary introduction routes
Resistance to some dip formulations has complicated control

Welfare Considerations

Sheep scab causes severe, persistent itching causing self-inflicted wounds and marked welfare harm. Affected sheep rub and bite affected areas continuously, causing open lesions susceptible to flystrike. Prompt treatment and biosecurity preventing reintroduction are welfare priorities.

What You Can Do

Treat all sheep from the same group when scab is confirmed
Implement strict quarantine for bought-in sheep
Report suspected scab cases to APHA as required by law
