The study was included 70 native donkeys at age 3-4 years, 60 animals naturally infected with gastrointestinal parasite and 10 clinically normal served as control group. Coprological examinations revealed that the donkeys were infected with Nematodes such as Large strongyles Strongylus spp. 70%, Triodontophorusspp. 36.6%, Smallstrongyles (caythostomines) 33.3%, Trichostrongylus axei 33.3%, Parascaris equorum 20%, Dictyocaulus arnfieldi 13.3%, Strongyloides westeri 10%, Habronema musca 10%, Oxyuris equi 6.6% and Trematode Worm Gastrodiscus spp., Dicroceolium spp. 3.3%. The rate of a single infection was 20% and mixed infection was 80%. Diagnoses was based on the measurement and the characteristic shapes of eggs and larvae. Results indicate that diseased donkeys exhibited emaciation 30%, rough coat 68.3%, pale mucous membranes 60%, Pica 53.3%, colic 68.3%, moist ralse 6.6%. Significant decrease (P<0.05) were encountered in the RBCS count (P<0.01) and Hb and PCV values of infected donkeys compared with control, while there were significant increase at (P<0.05) in WBCS and eosinophils at (P<0.01).
