There is only one worm species that can infect cattle, sheep, goats, pigs and horses and for practical purposes it isn't very important. When another animal species eats the goat parasite larvae they will be killed. Unfortunately, it takes a long time for the worm eggs and larvae to die off if the pasture is just left empty. A year or at least an entire grazing season is required. This is usually impractical and it also means that the kind of rotational grazing at short intervals used to maximize pasture production usually doesn't have much impact on parasites.
Goats seem to be more sensitive than other livestock species in terms of abortion in late lactation.
Abortion cases have been reported. However, it is not clear whether or not abortion was provoked by the wormer used or simply by the stress related to animal handling and deworming. Some products are to be avoided. Albendazole should not be used in pregnant does. The primary pathology associated with coccidiosis involves intestinal cell destruction.
