The epidemiology and chemotherapy of haemonchosis in goats were studied at the out door dinics of the Dept. of Clinical Medicine and Surgery, University of Agrculture, Faisalad. Of 2540 goat accessions to our dinic over a one year period (March, 1993 to February , 1994), haemonchosos was recorded in 462 (18.81%) animals. The prevalence was significantly higher (53%) among young animals than adult (4 7%), Sex had no bearing on the prevalence of the disease. The spring season was most strongly associated with the occurrence of the disease (24.81%) followed by summer (17.02%), autumn (16.96%). A single subcutaneous injection of Avermection Bi (Ivomec R-MSD) @ 200ug/kg was found to be 100% effective against haemonchosisin goats.
