Gastrointestinal nematode infections are among the major health problems limiting the productivity in dairy cattle. A cross sectional study was conducted from October 2014 to May 2015, to estimate the prevalence and identify the major genera of nematodes in dairy cattle farms in Dire Dawa Administration, eastern Ethiopia. A total of 384 fecal samples from dairy cattle were collected and examined for nematode infection using standard coprological methods. Out of these, 203 (52.9%) animals were found positive for one or mixed nematode infection. Specifically, Trichostrongylus (20.1%), Strongyliods (16.1%), Oesophagostomum (13. 3%), Haemonchus (10.9%), Dictyocaulus (9.4%) and Trichuris (4.9%) were the identified genera in descending order of prevalence. The proportion of mixed infection was 97 (25.26%).The highest percentage was recorded with Trichostrongylus and Dictyocaulus 13(13.4%). Among the potential associated risk factors, history of de-worming (p=0.00) and body condition (p=0.02) were found significantly associated with the occurrence of nematode infection. Source of animals, age and breed of the animals revealed no significant relation with prevalence of nematodes. The degree of infection revealed that majority (50.74%) of the examined animals were moderately infected with nematode parasite. Therefore, strategic de worming should be practiced in the dairy farms.
