Anthelmintics
BVA guidance on the use of anthelmintics in grazing animals
In this section you can find out more about the development of resistance to anthelmintics used in the treatment of worms and other endoparasites in grazing animals. It provides the British Veterinary Association’s (BVA) advice on the responsible use of anthelmintics to reduce the development of resistance to them in grazing animals.
Background
The misuse of anthelmintics and the development of resistance to them by endoparasites is an increasing problem in the treatment of sheep, goats and horses worldwide. Resistance is also an emerging problem in cattle.
Such resistance is a serious and increasing threat to the health and welfare of grazing animals. If unchecked, it will have a potentially catastrophic impact on animal welfare and economic production.
Anthelmintics are a necessary option for treatment but their use must be judicious, based on sound veterinary principles and a good understanding of epidemiology. Every application increases the risk of development of resistance to anthelmintics.
