It has a high population of livestock. However. the prevalence of a number of important diseases has impeded the rational exploitation of this resource. In recent years a nation-wide survey of livestock diseases is being conducted to identify, map infected areas and suggest appropriate measures amongst which parasitic diseases are given considerable attention. Accordingly, an investigation of the seasonal incidence of ovine helminthiasis in selected sites of various ecological zones was carried out for a period of one year to provide baseline information. Thus, the local occurrence of the Helminth of the genera of I~asic Paramphistomum, ~unostomllm., Chahert.ia, Dictyoc~.

The relative frequency and temporal patterns of these parasites ha~e also been studied. The results clearly show the bearing of various meteorological factors, particularly moisture, have on the seasonal incidence of the helminths infecting sheep.
