Bovine Respiratory Syncytial Virus: Welfare Implications

BRSV is a major cause of respiratory disease in cattle, particularly calves. This page covers its welfare implications, recognition, and control.

Key Facts

BRSV causes severe lower respiratory tract disease in young cattle
Clinical signs include fever, rapid breathing, coughing, and nasal discharge
Secondary bacterial infections worsen the condition significantly
Outbreaks cause high morbidity and can be fatal in young calves
Vaccination programmes can significantly reduce disease burden
Welfare impacts include respiratory distress, pain, and reduced growth

Welfare Considerations and Management

Treatment involves supportive care, anti-inflammatories, and antibiotics for secondary infections. Early intervention improves outcomes. Vaccination of dams and calves provides important protection. Welfare-centred management includes good ventilation, low stocking density, and early detection protocols.

What You Can Do

Maintain good ventilation in calf housing to reduce viral load
Vaccination is the most effective preventive measure
Early treatment of affected calves reduces severity and spread
Monitor groups for signs of respiratory disease daily
