Cross sectional study was conducted to determine the prevalence of gastro intestinal parasite and protozoan emeria, to determine the common risk factor and to identify the commonly existing parasitic eggs at Horoguduru animal production and research center of Wollega University. To determine the sample size, an expected prevalence of 50% was taken into consideration since there was no research work on gastro intestinal parasitic eggs at the center. 384 animals’ fecal samples were collected directly from the rectum of cattle into a universal bottle containing 10% formalin and transported to the laboratory for examination. Carpological examination was done at Wollega University Shambu campus animal science and, food and nutrition department. Coprological examinations were made within 12 hours after sample collection. Eggs of nematode, cestode and trimatodes were identified. In this study egg of paramphistomum, fasciola, haemonchus, strongylus and monezia are the commonly identified eggs by floatation and sedimentation techniques. Sedimentation technique was used to detect the presence of fluke eggs in the fecal samples. The result showed that the overall prevalence of gastro intestinal parasite is 133/384 (34.6%).The result showed that the prevalence were 27.8% in young age group, 40% in adult age group and 35.4% in old age group. The result also reported that the prevalence of the parasite was 48/86(55.81%) in cross breed and 85/298(28.5%) in local breed. The study depicted that the prevalence of the parasitic egg are 88/219(40.18%) in female animals and 45/165 (27.27%) in male animals. In this study from the total of 134 infected animals 85/134(63%) were infected by single infection and49/134 (36.57%) were infected at least with two different genera of gastro intestinal and protozoan parasites. The prevalence of eggs of each single infection were Paramphistomum 27/85(31.76%), Fasciola 17/85(20%), Ascaris 15/85(17.95%), Monezia 9/85(10.59%), Tricuris 7/85(8.24%), Strongyloid types 6/85(7.06%), Haemonchus 2/85(2.53%), and 1/85(1.18%) of Nematodurous and Emeria It also showed that from the total of multiple infections 9/49(18.36%) was infected with three types of parasitic genera and 40/49 (81.63%) were infected with two different genera. In conclusion separate grazing land for young animals (calves), separate Water and feed trough for different age category and risk factors based strategic deworming were recommended.
