The Ulster Farmers’ Union is advising farmers to plan ahead following confirmation from MSD Animal Health UK that Bovilis® Huskvac will be discontinued after the 2027 lungworm season.
While the withdrawal of Bovilis® Huskvac represents a significant change for Northern Ireland cattle producers, early preparation will be essential. From 2028 onwards, lungworm control programmes will need to rely on alternative management approaches. The UFU encourages farmers to speak with their veterinary practice to discuss lungworm risk, review herd health plans and identify practical measures to protect cattle health at grass in future years.
The decision to discontinue Bovilis® Huskvac follows MSD Animal Health’s announcement in 2023 that it would close its UK manufacturing plants between 2027 and 2030 as part of a wider global review of manufacturing and supply operations.
Lungworm, caused by Dictyocaulus viviparus, can affect both dairy and beef herds, particularly grazing youngstock, although adult cattle can also be at risk. Clinical signs of lungworm infection can include coughing, laboured breathing, loss of condition, reduced growth rates and reduced milk yield. In severe cases, lungworm can cause serious disease and may even result in death.
