Risk Factors Associated with the Occurrence of Gastrointestinal Helminths among Indigenous Donkeys (Equus asinus) in Northeastern Nigeria

Aim. This survey study was conducted from April 2014 through March 2015 in Bauchi, Yobe, and Gombe states, northeastern Nigeria, to explore the risk factors associated with the occurrence of gastrointestinal helminthosis among indigenous donkeys (Equus asinus).Materials and Methods. A total of six hundred fresh faecal samples were randomly collected from indigenous donkeys of varying age, sex, and settlements. Simple flotation and sedimentation techniques were used for the detection of helminths eggs.Results. Three gastrointestinal nematode parasites were encountered includingStrongyle,Parascaris equorum, andOxyuris equi. An overall prevalence of 98.3% was obtained, of which 78.3%, 40.3%, and 17.5% were, respectively, fromStrongyle,Parascaris equorum, andOxyuris equi. Age, sex, and season were not statistically associated with the risk of helminth infection as were the different study areas (p>0.05). However, body condition score, settlement, anthelminthic medication history, and management practices were significantly associated with the risk of gastrointestinal helminthosis. Statistically high prevalence of helminthic infections was observed in donkeys, with poor (thin) body condition, from rural settlements, that were not dewormed and raised under poor management systems (p<0.001).Conclusion. It is concluded from the study that gastrointestinal helminths particularlyStrongylewere endemic among the indigenous donkeys in northeastern Nigeria. Further control and preventive measures were discussed.
