How is BVD Transmitted Among Dairy Cows?
Bovine Viral Diarrhoea Virus (BVDV) is highly contagious, spreading rapidly among dairy cows through several transmission routes.
Primary Modes of Transmission
- Direct Contact: The most common transmission route is direct contact with infected animals. BVDV is present in saliva, nasal discharge, urine, and faeces of infected cattle.
- Vertical Transmission: Pregnant cows infected with BVDV can transmit the virus to their fetuses, resulting in persistently infected (PI) calves, which continue to shed the virus throughout their lives.
- Indirect Contact: Contaminated equipment, feed, water, and personnel can also facilitate the spread of BVDV within a herd.
Importance of Biosecurity
- Implementing strict biosecurity measures, such as isolating new or sick animals, maintaining clean equipment, and monitoring visitors, can significantly reduce the risk of BVDV transmission.
Preventing BVD transmission is vital for the health and productivity of your dairy herd. For more information on effective biosecurity measures and BVD testing, contact FarmLab Diagnostics. Our experts can help you implement strategies to protect your herd. Contact Us today to learn more.
