Executive Summary
- BVDV causes significant economic losses in the beef industry, ranging from $15 to $88 per head due to reduced herd productivity and health.
- A significant percentage of producers lack basic knowledge about BVDV, contributing to the persistence of the disease in cattle herds.
- Effective management of BVDV requires testing calves early to identify and remove persistently infected (PI) cattle, along with strategic vaccination protocols.
Event Overview
Bovine Viral Diarrhea Virus (BVDV) is a costly disease impacting the beef and dairy industries. It causes immunosuppression, leading to increased calf death losses from diseases like scours and pneumonia, as well as poor weaning weights. The disease is caused by three related viruses and 19 subtypes. A significant percentage of cattle are persistently infected, and many producers lack sufficient knowledge about BVDV, hindering effective control measures. Testing and proper vaccination protocols are crucial for managing the disease.

Key Details & Data Points
- What: Bovine Viral Diarrhea Virus (BVDV) causes immunosuppression, reduced productivity, and economic losses in cattle. It includes transient infection (TI) and persistent infection (PI). PI cattle result from infection during fetal development and can significantly impact herd health.
- Who: Dr. Thomas Passler (Auburn University), Dr. Dan Thomson (Iowa State University professor emeritus), Craig A. Payne (University of Missouri), Celeste Morris (University of Missouri), U.S. beef and dairy producers, Indexx Laboratories, National Animal Health Monitoring System (NAHMS)
- When: The NAHMS study was conducted in 2017 and the summary was released in 2023. Losses cited are from older data from 2002 and 2008. Infection during fetal development occurs between 40 and 125 days of gestation.
- Where: United States (specifically 24 major cow-calf states representing 86.6% of U.S. beef cow inventory), Auburn University, Iowa State University, University of Missouri.
Key Statistics:
- Key statistic 1: $15-$88 per head (conservative average loss due to BVDV)
- Key statistic 2: 0.5% (estimated percentage of U.S. cattle persistently infected with BVDV)
- Key statistic 3: 57.5% (percentage of producers who knew some basics about BVDV in 2017 NAHMS study)
Analysis & Context
The article highlights the significant economic impact of BVDV on the beef industry and the concerning lack of awareness among producers. The information presented emphasizes the need for proactive testing strategies, appropriate vaccination protocols, and improved biosecurity measures to effectively manage and mitigate the risks associated with BVDV. The expert opinions from veterinarians and researchers provide valuable insights into the complexities of the disease and the importance of a comprehensive approach to prevention and control.
Notable Quotes
"(BVDV) has evolved over the years and is not a single virus or just a diarrhea-causing problem. Today it’s made up of three related viruses and 19 subtypes that cause similar diseases."
"We’re using a lot more intranasal vaccinations, thinking that we’re covering for BVDV when we’re actually not."
"Vaccination alone cannot counter the effects PI animals can have.”
Conclusion
BVDV remains a persistent and costly threat to the beef industry. Effective management requires a multi-faceted approach including increased producer education, strategic testing to identify and remove PI cattle, and careful selection and administration of vaccines. Further research and ongoing vigilance are crucial to minimize the impact of this disease and improve herd health and productivity.
