Shift of rumen fluke spatial clusters due to flukicide restrictions
Between March 2010 and October 2012 only two medications (Albendazole or Oxyclozanide) were licensed for use against liver fluke in Irish dairy herds. Oxyclozanide is also active against rumen flukes, a parasite which shares many characteristics with the liver fluke. Here we show density clusters of cattle infected with rumen fluke between 2011 and 2014. A change from north to south in the distribution of the density clusters can be seen from 2011 to 2014. This is interesting as the southern part of the Munster region has a greater proportion of dairy herds as compared to beef herds. From the end of 2012 on, more treatment options became available. As a result the use of Oxyclozanide, and therefore control of rumen fluke, has declined in dairy herds. You win some, you lose some.
