    Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its saprotrophs, parasites feed on living hosts, though some parasitic fungi, for instance, may continue to feed on hosts they have commensalism and mutualism, the parasitic relationship harms the host, either feeding on it or, as in the case of . The aim of this and the following chapter is to give a full account of the parasites of sheep, so that farmers and shepherds may be able to control these unwelcome parasites more effectively and thereby substantially improve the profitability of the flock and the welfare of the animals.

    The external parasites or ectoparasites live on or in the skin of sheep and their presence on an animal is usually referred to as an infestation rather than an infection. Some parasites such as keds do little or no harm to their host. Others cause serious damage or irritation, and lice and the mites responsible for sheep scab are examples. parasites, although certain parasites may affect one species more severely than the other, and treatment methods may vary between sheep and goats. In order to know how best to prevent future problems with parasites and control current infestations, it is necessary to understand the general life cycle of the parasites most common to sheep and goats.

    Older sheep and goats that have worn teeth have difficulty in eating and will lose condition, become more prone to diseases and breed less than younger animals. Roughly 20% of the sheep in a flock are responsible for depositing 80% of the parasite eggs on a pasture. In general, hair breeds of sheep have more individuals with resistance to parasites than wool breeds. However, regardless of the breed, there are individual animals in every flock that will be more susceptible and more resistant to parasites.
