Results By the end of Q2 of 2018 just over 1.92 million calves had been tested, representing approximately 82% of the anticipated calf crop for the year. The prevalence of PI births in 2018 continues to decline, with only 0.05% of calves tested to the end of Q2 being found to be persistently infected (PI) with BVDV (as compared to 0.10% in 2017, Figure 1), with these being located in 0.9% of 83,000 breeding herds (compared to 2.01% in 2017, Figure 2). This represents a decrease in PI prevalence of 50% from that seen in 2017, from 0.10% to 0.05%, and is a reduction of more than twelve-fold when compared to the prevalence at the start of the compulsory phase of the programme in 2013, when 0.66% of the calves born were PI. Updated programme results are available on a weekly basis online click here .
