Addisu Bacha, Berihu Haftu

Livestock production constitutes one of the principal means of achieving improved living standards in many regions of the developing world including Ethiopia. A cross sectional study was conducted from November 2013 to April 2014 to determine the prevalence of gastrointestinal nematodes and coccidia parasites affecting cattle in west Arsi zone using flotation technique to investigate helminthes eggs. A total 384 fecal samples of cattle from different districts of west Arsi zone (Arsi-negele, Shashemene and Kofele) were collected and examined for incidence of gastrointestinal nematodes and coccidial infestation. Out of 384 animals examined, 188 (49%) animals were positive for gastro-intestinal nematodes and coccidian; and out of these positive animals 109 (57.97%) were infested with single genera of gastro-intestinal nematodes and coccidian, which include: ostertagia spp 7 (1.8%), oesophagostomum spp 5 (1.3%), strongloid spp 10 (2.6%), Emeria spp 11 (2.9%), Trychostrongylus spp 14 (3.6%), hemonchus spp 45 (11.7%), Bunostomum spp 17 (4.4%) and the rest 79 (42.02%) animals were infested with mixed genera of gastro-intestinal nematodes. These include oesophagostomum spp with Trychostrongylus spp 37 (9.6%), ostertagia spp with hemonchus spp 15 (3.9%), Trychostrongylus spp with hemonchus spp 17 (4.4%) and strongloid spp with Bunostomum spp 10 (2.6%). The prevalence of gastro-intestinal nematodes and coccidia was higher in adult and young animals as compared with calves, higher prevalence were also seen were communal grazing and watering areas are common.
