Where do sheep and goats get these worms? Where does this leave us? A good time to do this is about two weeks post deworming in the summer. Parasitic infestation can result in decreased production of ewes and lambs on pasture through reduced milk production and poor weight gains, and even death may occur in extreme cases.

FEC is recommended throughout the grazing season to assess the levels of worms present and also assess the effectiveness The enemy: Haemonchus contortus. Fewer sheep result in fewer shed worm eggs within a given area, and thereby reducing parasite loads. The only internal parasite of sheep that you will see in the stool is segments of the tapeworm. two weeks after drenching. A full list is available at.
