Although no direct causal link between the use of Pregsure BVD and Bovine Neonatal Pancytopenia (BNP), commonly known as Bleeding Calf Syndrome, has been proven, it has been suggested that it may be associated in some way with the disease.

What causes the syndrome is unknown, but it is believed many factors may be involved. SAC advises farmers not to stop using their proven vaccination programmes and that Pfizer should be consulted for advice concerning unused doses of the vaccine.
So far this year SAC has confirmed 72 calves with Bleeding Calf Syndrome (BCS). These calves came from 61 farms with submissions received by all of Scotland’s eight Disease Surveillance Centres.
The condition was first reported in Europe in 2008. SAC vets received their first suspected case in April 2009 and had confirmed 48 cases on 35 Scottish farms by the end of the year.
Affected calves are less than 28 days old and can have persistent fever with bleeding from the nose, gums, ear-tag holes and injection sites. Intestinal bleeding can also occur with affected calves passing dark, tarry dung.
