BVD virus is major economic threat
BVD is widespread in the national herd and causing concern among vets, especially as it is difficult to spot and many farmers are unaware their herds are affected. Apart from causing acute diarrhoea in newly affected herds, the highly infectious, viral disease can lead to infertility problems, embryonic deaths, abortions, congenitally damaged calves and persistently infected (PI) calves that are likely to die of mucosal disease within two years.
Several countries, including Denmark, Sweden and Finland, have virtually eliminated BVD.
