The Ulster Farmers’ Union (UFU) has asked the NI Meat Exporters’ Association (NIMEA) to consider implementing a ban on animals persistently infected (PI) with Bovine Viral Diarrhoea (BVD) from entering their premises, effective from the end of March this year.If agreed, it would leave those herd keepers who retain PIs with very limited options, given that these animals are already subject to individual movement restrictions which currently mean that they cannot be moved off a farm, except to slaughter.
