Drench efficacy tests- a useful indicator if used well

摘要

Defra recently announced it would fund an annual veterinary review for English flocks as part of the Animal Health and Welfare Pathway.From April 2022 this will include funding for a drench efficacy test, which will allow sheep farmers to look at how effective the anthelmintic they use is at controlling worms in their flocks.For farmers in England accessing the funding, or any producer wanting to explore this option, what is to be gained from testing? Effective anthelmintic treatments improve sheep performance.Tests carried out correctly provide an understanding of how an anthelmintic is performing, giving an early indication of falling efficacy.This allows farmers to stay in control and implement changes earlier.
