BVD in­ci­dence halved in the past year, with only 0.05% out of more than two mil­lion calves tested in 2019 found to be per­sis­tently in­fected (PI).

The in­ci­dence was 0.1% in 2017. The PI calves were in 1% of 83,000 breed­ing herds tested (com­pared to 2% in 2017).

Fur­ther­more, fig­ures up to Oc­to­ber 8 showed that only 53 PIS of the 1,115 born this year were still alive. The ma­jor­ity of these were born in Au­gust and Septem­ber, but a small num­ber were born ear­lier, the old­est be­ing born in De­cem­ber 2017.

Only 12 herds were re­tain­ing PIS for more than five weeks af­ter their ini­tial test re­sult. There are no PI an­i­mals alive in Louth, Dublin, Wick­low, Car­low and Wex­ford. A monthly map pub­lished by AHI (see an­i­mal­healthire­ in­di­cates where live PI an­i­mals are lo­cated.
