Bovine Viral Diarrhoea (BVD) is estimated to cost more than $150 million every year.

Bovine Viral Diarrhoea (BVD) is estimated to cost New Zealand's dairy and beef industries more than $150 million every year, yet many of the tools needed to control it are already well understood. After more than 25 years in veterinary practice, Andrew Weir, animal health technical specialist at LIC, has seen firsthand the impact BVD can have on herd performance. We asked him about the role of persistently infected (PI) animals and the practical steps farmers can take to reduce their risk.

Getting some post-mortems done on light ewes in your flock can be very helpful.

When a cow goes down after calving, it is easy to blame the calving itself. Milk fever, calving stress, poor weather, bad luck. Yet many down cows are not caused by one dramatic event. They are the end result of poorly transitioned cows entering calving under nutritional pressure.
