BVD Key Messages 2025

The Irish BVDV eradication programme has made significant progress in reducing the prevalence of virus positive animals. At the end of 2024:

  • 96.4% of breeding herds and 97.5% of all herds have Negative Herd Status (NHS) and 0.31% of breeding herds and 0.18% of all herds had positive results in 2024.
  • There was a 24% reduction in herds with positive results when compared to 2023.
  • 99.7% of bovine animals had a negative BVD status, with remainder mostly untested. 0.02% of calves tested during 2024 returned BVD virus positive results, which when put in the context of all the cattle in Ireland, is an animal-level prevalence of 0.006%.

The new Animal Health Law (AHL) sets out the requirements for recognition of BVD programmes and BVD-freedom at EU level for the first time. An application for recognition of the Irish BVD programme was submitted in 2022 and the programme was officially approved on the 18th July 2022. This approval is a key milestone for the programme and a prerequisite for applying for recognition for freedom.

Summary of BVD Eradication Key Messages for 2025

  1.  Tissue tag testing remains compulsory for 2025.
  2.  Tissue tag-test all calves as soon as possible after birth. Where positive or inconclusive tissue tag results are obtained, isolate and remove these calves promptly to obtain the higher financial support from DAFM. Confirmatory testing of these animals is no longer permitted.
  3.  Test any animals of unknown status to obtain Negative Herd Status (NHS) and avail of cheaper testing.
  4.  New infections are often a result of transmission from other herds in the vicinity or introduction of pregnant dams carrying an infected calf. Review biosecurity to minimise these risks, with a focus on movement of animals (including pregnant dams), people (including the farmer) or equipment or contact across farm boundaries.
  5. Farms that either share a boundary or are within 400m of a herd with a positive or inconclusive result will receive a neighbourhood notification. These herds should take every precaution to prevent the spread of BVD.
