Nematode parasite burdens of ewes grazing on grass/lucerne pasture increased 58-fold after the first autumn rains in the southern Cape Province. Lambs were infected before the age of 8 weeks and harboured large burdens of nematodes before the age of 14 weeks. The nematodes detected were Teladorsagia spp., Nematodirus spp., and Trichostrongylus spp. Oestrus ovis infections were present in 96% of the ewes, and 92% of the lambs above the age of 3 weeks. Anthelmintic treatments in autumn, winter and spring are recommended for controlling parasites of sheep in this region.
