Fascioliasis

An important stage of the Liver fluke life cycle takes place in mud snails and requires wet and warm conditions (above 7 – 10°C) during the summer months. Over the last couple of years unseasonal weather has seen these conditions well into autumn and winter. This means that sheep and cattle are still being infected later in the season and more frequent testing and treatment may be required.

Fascioliasis can have a serious financial impact on a sheep farm with immediate losses up to 10 per cent caused by acute/subacute disease. Chronic disease could half profits by reducing lamb crop and increasing ewe mortality. Lack of treatment in cattle will lead to reduced growth and yields and discarded milk if treatment is no targeted.

We recommend testing your sheep and cattle for the presence of Liver fluke. Treatment needs to be targeted at your flock/herd and will vary from farm to farm. Please discuss your individual requirements with your vet to develop a treatment plan for the coming months.
