A cross sectional study was conducted from October 2013 to April 2014 in and around Kombolcha town to estimate the prevalence of gastro intestinal tract helminthes infection and to identify the common GIT helminthes parasites of equines. Gross examination, direct fecal smear, sedimentation and floatation techniques were utilized to identify the eggs of parasites in feces. A total of 384 horses, mules and donkeys were examined for gastrointestinal parasites. The overall prevalence of gastrointestinal parasites was 73.2% (281 from 384) with 57.0% (73 from 128), 82.5% (160 from 194) and 77.4% (48 from 62) in horses, donkeys and mules respectively. Prevalence of Strongyle spp, Parascaris equorum, Oxyuris equi and Anoplocephala spp was 44.5%, 3.1%, 2.3%, and 3.1% respectively in horses. Prevalence of gastrointestinal parasites was 63.4%, 8.6%, 2.1% and 3.1% for Strongyle spp, Parascaris equorum, Oxyuris equi and Anoplocephala spp in donkeys, respectively and the prevalence of GIT parasites was 48.4%, 12.9%, 3.2% and 6.5% for Strongyle spp, Parascaris equorum, Oxyuris equi and Anoplocephala spp in mules respectively. There was statistically significant difference between species, age, and body condition and among different management systems in prevalence of equine gastrointestinal parasites (p<0.05). However, there was no statistically significant difference in prevalence of gastrointestinal parasites based on sex. In conclusion, the present study revealed higher prevalence of gastrointestinal parasites in equines. Therefore, regular deworming, improvement of housing and feeding management were recommended.
