Parasites affect every horse and are, therefore, of concern to every horse owner. The dangers cannot be ignored: it is vital to confront the problem in order to prevent unnecessary suffering to the horse and having to bear the financial burden of extra feed and veterinary bills. Written from a horse management rather than a veterinary perspective, this book describes the worm types and their life cycles and explains clearly the practical aspects of preventing worm infestation. Straightforward pasture management techniques, unbiased explanations of individual drug merits and sample worming programmes are all included to help reduce the risk to the horse from the incorrect use of drugs. This indispensable book is an essential purchase for every amateur and professional horse owner, as well as examination students.
