Guide to advances in the control of gastrointestinal roundworms in sheep

Abstract

Background: In the UK, diseases caused by gastrointestinal nematodes (GINs) are the most expensive endemic diseases, being a major cause of morbidity, mortality and lost production in sheep flocks. Control is complicated by the increasing prevalence of anthelmintic resistance in the GIN population and changes in epidemiology, partially driven by climate change. Therefore, there is great emphasis among sheep farmers and veterinarians to find methods to successfully control GINs and prevent associated diseases. Aim of the article: This article outlines the different strategies that can be implemented on farm to try and sustainably control parasitic gastrointestinal nematodes of sheep.
