The relation of climate and topography to gastro-intestinal nematode worm egg counts of Angora goats in the Eastern Cape.

Haemonchus, Trichostrongylus, Ostertagia and Nematodirus worm populations of Angora goats, based on differential egg counts, are considered in relation to climatological and topographical data. Egg counts indicated that the estimated worm populations in goats that experienced wet circumstances were higher than those exposed to dry conditions. Wetness was assessed by relating spring, summer, and early autumn rainfalls to ground slope. It is proposed, that tactical anthelmintic treatments of goats be based on the degree of wetness of the grazing or property.
