Treatment of natural coccidial infection in Lambs using Monensin

Abstract

The therapeutic effect of monensin on natural coccidial infection was tested in two trials. Lambs with heavy mixed infections were fed a diet containing 20g monensin/tonne over a period of 14 days. In both trials and over period of 35 days, coccidial oocyst output in non-medicated lambs was reduced by 53.6%. In the medicated lambs, it was practically nil. Monenzin thus appears to have some therapeutic effect on sheep coccidiosis.
