This publication acquaints the reader with methods of preventing, controlling, and treating parasitism in sheep.
Parasites or worms affecting the digestive system are a severe health problem in sheep production. The economic losses from parasitism can be extensive, ranging from mortality or death loss to weight loss, reduced weight gain, reduced wool production, decreased milk yield resulting in lower lamb weights, poor reproductive performance, and the cost of medications and handling.
Coccidiosis, another costly intestinal parasite, but not caused by worm infestation, will be discussed briefly.
