IBR in Cattle: Welfare During Respiratory and Reproductive Disease
Infectious bovine rhinotracheitis (IBR) caused by bovine herpesvirus 1 creates significant welfare problems through respiratory disease, abortion, and fatal neonatal disease.
Key Facts
- IBR causes severe upper respiratory disease, conjunctivitis, and high fever in acutely infected cattle
- Abortion storms in pregnant cattle represent significant welfare emergencies in infected herds
- Fatal septicemia occurs in neonatal calves born to primary-infected dams
- Vaccination prevents disease expression but does not eliminate latent infection
- Many European countries have achieved IBR-free status through vaccination and testing
Welfare Considerations
IBR welfare impacts span multiple systems and animal groups. Acutely infected cattle experience severe respiratory distress, painful conjunctivitis causing excessive tearing and eye pain, and the systemic effects of high fever. Pregnant animals that abort lose pregnancies in mid to late gestation, and the abortive episode itself causes distress. Neonatal calves infected with the virus develop fatal septicemia. Prevention through comprehensive vaccination programs provides cost-effective welfare protection for all these groups. IBR-free accreditation programs eliminate the ongoing welfare burden of the virus from participating herds.
What You Can Do
- Implement comprehensive IBR vaccination programs for all cattle
- Participate in regional IBR eradication or accreditation programs
- Monitor for respiratory disease and conjunctivitis as early signs of IBR
- Isolate acutely sick cattle to prevent spread while providing supportive care
- Seek veterinary advice on managing pregnant animals in herds with IBR activity
