A unique resource for all those interested in the impact of worms on livestock, the anthelmintics used to get rid of them and the emerging problem of anthelmintic resistance. This book provides an over-arching view of past, present and suggested future strategies for control of gastrointestinal nematode parasites in sheep and cattle. The book begins with descriptions of the biology of gastrointestinal nematodes, the harm they cause to the host and their economic impact. The main body of the book deals with the control of worms, focusing on the use of anthelmintic drenches. The relationship between drenching practices and the development of drug resistance is discussed, as well as resistance management. The authors also break new ground by discussing alternative options for worm control, including: nutritional interventions, biological control, breeding for desirable genetics and artificially improving immunity to infection. They also offer useful recommendations for program development.

Understanding parasite biology and impact is essential when giving advice on parasite control in farm animals. In the first review devoted to parasites of domestic cattle and sheep alone, this book provides in-depth, focused advice which can be tailored to individual farms. It considers the impact of parasites, both as individual species and as co-infections, as well as epidemiological information, monitoring, and diagnostic procedures. Supported throughout by diagrams and photos to aid diagnosis, it also reviews the basis for control measures such as the responsible use of parasiticides, adaptive animal husbandry and other management practices.

Pyrantel Parasiticide Therapy in Humans and Domestic Animals presents a single source history and reference on the parasiticide activity and pharmacology of the tetrahydropyrimidines and their salts in humans and domestic animals, also collating evidence that resistance to pyrantel has developed in human and domestic animal nematodes. Other books of this nature have been compiled historically for specific anthelmintic compounds, but none has been written to date for the pyrantel family of drugs. Pyrantel, a nicotinic receptor agonist, has been used in domestic animal and human medicine since the 1970's to control two important nematode groups, the hookworms and the roundworms. Given the zoonotic potential of these parasites, pyrantel has served a dual role in helping to protect the health of both domestic animals and the public for more than 45 years.

This book provides a review of the current state of knowledge on all aspects of sheep nutrition. The main emphasis is on sheep grazing in systems that range from intensively utilized sown pastures to extensive rangelands.

This book presents a comprehensive and up to date account of the chemotherapy of parasitic diseases, both human and veterinary. The book starts with an overview of parasitic diseases. The body of the book is divided into two parts: antihelminthic drugs, and antiprotozoal drugs. Both parts start with chapters highlighting the 'biochemical targets' available for chemotherapeutic interference. Individual chapters deal with one chemical class of compounds and describe their origin, structure-activity relationship, mode of action, and methods of synthesis and their status both in clinical and veterinary practice. The book will be useful to a wide spectrum of readers: students embarking on a research career in parasitic chemotherapy, clinicians (and veterinarians) and clinical pharmacologists desiring detailed information about the drugs currently in use, and pharmaceutical technologists wanting to update their knowledge of the methods of manufacture.

- NEW case studies provide more opportunities to apply what you have learned, and bring to life a subject that can be dry and difficult. - UPDATED information throughout provides the most up-to-date coverage of the parasites most often seen in veterinary practice. - NEW! End-of-chapter matching exercises and online activities make study and review easier.
