ADVERTORIAL As this year’s winter


weather has been so different from last, parasites may not be behaving as we’d expect. So what should we be looking out for to avoid unpleasant surprises?


Liver fluke – challenge has been later and lower than normal, but many cale and sheep will be carrying low fluke burdens into spring. With only small numbers of adult fluke, animals are unlikely to show any signs of disease, but these few adults can produce enough eggs to provide a significant autumn challenge. Testing for evidence of fluke infection before cale and sheep go onto spring pastures will allow treatment to minimise pasture contamination with fluke eggs, reducing the fluke risk for autumn.


Coccidiosis – mostly a risk to young animals. Hygiene in calving and lambing areas to minimise transfer of faecal material to teats and then suckling calves or lambs can reduce risk. Monitoring oocyst levels, and strategic treatment before clinical signs develop, will help prevent the significant growth check that subclinical coccidial infections cause.


Nematodirus – this seasonal parasite challenge could be present much earlier than in ’normal‘ years. The SCOPS Nematodirus forecast (www.scops.org.uk/forecasts/ nematodirus-forecast/) will show when the risk warrants treatment on your farm.


Blowfly strike – another seasonal parasite that is weather/ temperature dependant. If the temperature stays above average we should expect an earlier blowfly challenge.
