AHI BULLETIN Progressing towards BVD eradication – Mid Year Review

T he national BVD eradication programme has had significant success in reducing the prevalence of the disease. As of 1st June, over 75% of this year’s calf crop have been born and tested. The BVD results show that further progress toward eradication has been made. In 2018 to-date, the prevalence has reduced by 50% from that seen in 2017, from 0.10% to 0.05% (Figure 1). And this reduction is even more dramatic when compared to the 0.66% prevalence in 2013, the first year of the compulsory programme, representing an estimated net benefit to farmers of 85 million euro in 2018 alone. • Substantial progress has been made in reducing the prevalence of PI animals in 2018. • Retention levels of PIs have reduced. • Animals whose status is not known should be identified and tested.

A key focus over the next months will be the identification and testing of the small proportion of animals whose BVD status is not known. Herd owners will be contacted within the next few weeks with details of these animals. Substantial improvements have also been made in reducing the extent to which PIs are retained on farm. Figures up to the end of May show that 156 PIs are still alive on farms, of which only 31 PI animals in 23 herds are being retained beyond 5 weeks.
