1,219 farmers took part in the survey: 44% beef and 56% dairy. For the first time, the survey was also tailored for the regions. 488 responses came from famers in England, 380 from Scotland, 164 from Wales and 237 from Northern Ireland.
Boehringer Ingelheim’s Matt Yarnall, who led the project, said: "Headline findings are that farmers have regrets about holding onto persistently infected animals (PIs) which, at the end of the day, no-one should be doing.
"The financial benefit of being free of BVD was estimated as being over £90 per cow per year and when asked what impact BVD has had on their herd, the majority of producers highlighted poor fertility and high levels of disease in the herd.”
Boehringer says the identification of persistently infected animals (PIs) through tag and testing, supported by improved herd biosecurity and vaccination, could cost as little as £10 per cow per year, representing a significant return on investment for a disease with severe financial impact.
Matt said: "Herd biosecurity is also hugely variable. The most commonly selected response was operating a closed herd but, as most practitioners will know, the definition of a true closed herd and the real-life execution of that can be two very different things."
Highlighting one of the other major challenges for producers in cattle-dense areas, results from Scotland that showed that 51% of farmers with neighbouring cattle are worried about their neighbours' BVD status.
Matt said: "Perhaps the most alarming finding was the lack of awareness of the intricacies of some BVD vaccination courses, especially around when they need to be restarted, in order to achieve the protection needed."
2017 survey data from last year showed that 71% of producers were failing to achieve adequate protection when using a BVD vaccine that requires a booster six months after the primary course.
Boehringer says the results showed this is mostly down to not properly understanding the exact nature of the timings for the two-dose primary course, dates of service and calving and then the booster date.
Matt added: "For any practitioner advising clients, the 2018 finding that a shocking 85% haven’t restarted a vaccination course when the majority should have done, should ideally serve as a clear call to action."
