We are delighted to welcome Claire Shand from Westgate Labs and vet David Rendle who is a specialist in equine internal medicine to discuss the fascinating and potentially confusing issues around parasite control in horses.
Traditional methods of parasite control centred around regular dosing of wormer but problems around growing worm resistance as well as the effect these chemicals have on the environment have become apparent. Targeted worming is now the preferred method.
“All horses need sustainable parasite control based on worm egg counts and tests to identify parasite burdens before they get to a level to cause illness while minimising chemical intervention to slow the development of wormer resistance.
“Not only is this better for our horses and often cheaper too, but it also benefits the environment. Worming chemicals are poisons and each time we dose our horses, metabolites from these are passed out into the dung and onto our pastures. These leach into the soil and get washed into watercourses, causing harm to microorganisms, insects, fish and aquatic organisms.”Claire Shand, Westgate Labs
One of the key indicator species that highlights the impact of worming chemicals on the environment is dung beetles. These hard-working insects can be described as nature’s bin men. They have the ability to clear-up large quantities of animal faeces by tunnelling and breeding within dung, feeding upon it and burying it below ground. This action fertilises and aerates soils, improving its ability to retain water and increasing nutrient availability to plants – beneficial for both root structures and other organisms. It is estimated that dung beetles provide ‘ecosystem services’ to the UK cattle industry valued at more than £367 million per year – and they could save even more if looked after better.
“The blanket use of worming chemicals in agriculture have been identified as a major part of their decline, so how do we get the balance right? Some strategic thinking to look after these insects will pay huge dividends to our time, our horse’s health and the environment in the long run. Definitely an investment worth making for all our sakes!”Claire Shand
