Sheep Welfare and Clostridial Vaccination

Clostridial diseases cause sudden death and acute suffering in sheep. Vaccination provides excellent protection and is one of the most cost-effective welfare interventions available.

Key Facts

Clostridial diseases include pulpy kidney, lamb dysentery, tetanus, and blackleg
Mortality from clostridial disease is rapid and is preceded by acute suffering
Combined clostridial vaccines covering multiple serotypes are highly effective
Vaccination of ewes protects lambs through colostrum for the first weeks of life
Booster vaccination timing is important for maximum protective antibody titres

Welfare Considerations

Clostridial vaccination is one of the most welfare-effective interventions in sheep production - preventing acute, painful death with a simple, inexpensive programme. Failure to vaccinate causes entirely preventable welfare harm.

What You Can Do

Ensure all sheep are included in an appropriate clostridial vaccination programme
Vaccinate ewes before lambing to protect lambs through colostrum
Follow manufacturer guidance on booster timing and vaccination schedules
Advocate for vaccination compliance in sheep welfare certification schemes
