Gastrointestinal nematodes infect ruminant livestock throughout the world and are an important cause of disease and production loss. Since their invention, producers have heavily relied on broad spectrum anthelmintics to help control these parasites, however, intensive use has resulted in widespread resistance issues in nematode populations, especially Haemonchus contortus. Addressing the concerns of anthelmintic resistance, this book brings together research on management practices for controlling these nematodes in small ruminants. It covers: - The nematodes of greatest importance, such as Haemonchus contortus, Teladorsagia circumcincta, and Trichostrongylous spp., which frequently result in parasitic gastroenteritis; - Alternative approaches for nematode control, including the importance of adequate nutrition, methods for reducing pasture contamination, the role of genetics, grazing management systems and different forages; - Insights from the cattle industry, and where lessons can be learned across the species divide. With a focus on all small ruminants; sheep, goats and camelids, this book provides a useful resource for researchers and students of veterinary science, as well as practicing veterinarians and extension specialists.
