Optimising BVD control in beef herds

Previous research studies looking at the effects of BVD on New Zealand dairy herds have shown that controlling the disease can have many positive benefits on animal health and production.  Much less is currently known about BVD in beef herds, which have very different management styles and risk factors for disease transmission than dairy herds.  In particular, there are significant knowledge gaps around:

  • whether being unable to remove persistently infected (PI) calves from the herd until weaning will prevent us from breaking the BVD transmission cycle in herds
  • whether sheep that are co-grazed with infected cattle may be serving as a reservoir for the virus
  • whether we can screen beef calves for BVD antibodies at weaning to determine if the herd has recently been exposed to BVD

Over the first two project years, we are running several field studies to learn more about how the disease spreads within beef herds, how much it impacts herd performance, and how we should design BVD control plans to fit with each herd's unique management style.
