Supports separating pregnant heifers from sheep; leaves open validation of control programs in prospective studies.
Natural transmission of Border disease virus (genotype 3) from infected sheep to pregnant heifers causes a high rate of abortion, highlighting the need for pestivirus control programs.
Krametter‐Froetscher et al. (2010) studied Border disease virus (BDV) infection (n=8). Natural contact with persistently Border disease virus (BDV)-infected sheep was evaluated on Abortion. Natural exposure of pregnant heifers to Border disease virus (genotype 3) from infected sheep resulted in an abortion rate of 62.5% (5 of 8 heifers).
