BVD movement restrictions on breeding-age females begins 1 March 2026
DAERA is to introduce new movement restrictions for breeding age females in herds where a Bovine Viral Diarrhoea (BVD) positive animal has been detected.
The new measures begin on 1 March 2026, apply to all females at least 12 months old in affected herds and address the significant risk posed by so called ‘trojan’ animals – pregnant females exposed to BVD during gestation whose calves may be born persistently infected with BVD virus.
These animals can unknowingly introduce BVD into previously uninfected herds.
The new controls form part of the phased implementation of the BVD Control Order (NI) 2024 and represent the next step in strengthening Northern Ireland’s BVD eradication programme.
DAERA Minister Andrew Muir said: “The introduction of ‘trojan’ restrictions marks another essential step towards eliminating BVD from Northern Ireland. The movement of pregnant females that may be carrying BVD infected calves is a hidden source of disease spread and one of the most difficult to control. These new rules directly target that risk.
“Farmers across Northern Ireland have worked hard to reduce disease levels, and these additional controls will help protect that progress. I encourage keepers to work closely with their vets, ensure timely testing, and remain aware of the responsibilities that now apply.”
The Minister concluded: “Through these new requirements, herd keepers can safeguard their own herd, support their neighbours and help drive this disease out of our cattle population once and for all.”
Breeding age females in herds with a BVD positive animal will be prohibited from moving from the herd for up to 41 weeks following removal of the last BVD positive animal. Restrictions will remain in place until the female has calved and its calf has tested negative for BVD. They may also be lifted earlier if certain blood tests are carried out.
Further details on how the measures will be applied and guidance on minimising their impact are available on the DAERA website: https://www.daera-ni.gov.uk/publications/bovine-viral-diarrhoea-bvd-herd-restrictions
