Persistence of the efficacy of copper oxide wire particles against Haemonchus contortus in grazing South African goats

Abstract

A study was conducted to examine the duration of anthelmintic effect of copper oxide wire particles (COWP) in grazing goats, as data for the persistence of efficacy of COWP in this host species is limited.
