Cattle Calf Scour Prevention and Treatment

Neonatal calf scour (diarrhoea) is the leading cause of calf mortality under one month old, causing significant welfare impacts and economic losses.

Key Facts

Calf scour causes an estimated 25% of calf deaths under one month
Pathogens including rotavirus, coronavirus, Cryptosporidium, and E. coli cause disease
Dehydration from fluid loss is the primary cause of death
Oral rehydration therapy corrects dehydration in most mild to moderate cases
Colostrum management and hygiene are the most effective prevention strategies

Welfare Considerations

Calves with scour experience abdominal pain, weakness, and rapid deterioration from dehydration. Without treatment, death can occur within days. Even with treatment, affected calves suffer during the illness period. Preventive measures including colostrum management, vaccination, and hygiene dramatically reduce incidence and prevent the associated suffering.

What You Can Do

Ensure all calves receive adequate colostrum within 6 hours of birth
Implement vaccination programmes for rotavirus and coronavirus in calf scour prevention
Seek veterinary advice early for scouring calves to assess dehydration and treatment need
