Minister for Agriculture, Food and the Marine Charlie McConalogue has urged renewed caution as the Bovine Viral Diarrhoea (BVD) eradication programme approaches a particularly critical juncture.
The breeding season is the high-risk period for the generation of BVD persistently infected (PI) cattle. As the national prevalence of BVD decreases, so too does the natural immunity to BVD. This, coupled with reduced levels of vaccination across the country, means many herds are at increased susceptibility to infection.
The incursion of BVD into such herds with reduced immunity can have devastating impacts and lead to the development of further BVD persistently infected cattle. In the past number of weeks, epidemiological investigations have identified the emergence of a small number of local clusters of infection, with infection having spread between herds – this is thought to result from the movement of animals, equipment and people. In this context, the department is asking herd owners to refocus on biosecurity – to protect their own herds and support the final push toward BVD freedom.
The department encourages particular attention be paid to a number of aspects ahead of the breeding season:
Commenting Minister McConalogue said:
"Working with Animal Health Ireland, Irish farmers have made tremendous progress in the elimination of BVD. The programme is now at a critical juncture and I am encouraging all farmers to be mindful of the importance of biosecurity practices including the washing and disinfection of any shared machinery or facilities, to reduce the risk of infection so that we as a country can achieve BVD freedom, providing long term benefit for livestock farmers in the country.
“Huge progress has been made and the finishing is truly in sight. By working collectively and collaboratively, we can ensure we eradicate BVD as soon as possible.”
Since the commencement of the BVD eradication programme in 2013, there has been considerable progress with the herd level incidence falling from 11.27% in 2013 to 0.26% at the end of 2022, more than a forty fold reduction. Last year the national BVD programme was approved by the EU Commission, an important step to recognition of national freedom.
