Wet Autumn Requires Vigilance, UK Farmers Told02 February 2015
Stock keepers should be vigilant in the face of a mild, wet autumn which has seen the UK receive many rain systems and southerly winds.
Although not expected to be a terrible year for disease and parasites, the winter months will require control programmes to be executed to avoid problems, advises the National Animal Disease Information Service (NADIS).
- Winter 2014/5 was predicted to be a low/moderate risk year but disease may still occur on many farms unless control measures are implemented
- All efforts must be taken to reduce reliance on triclabendazole by husbandry measures and the use of other treatments when appropriate.
- Closantel and nitroxynil are very effective against immature flukes from around 7 weeks post infestation and should be used for the treatment of chronic fasciolosis.
- Albendazole and oxyclozanide are effective from 10-14 weeks post infestation and can be used when treatment is recommended to remove adult flukes in late spring (often in May).
- Quarantine treatments must be carefully considered for all introduced sheep and cattle.
