ABSTRACT

Aim: This study aimed to investigate the prevalence and intensity of nematode infection among slaughtered donkeys in Kaltungo, Nigeria.

Materials and Methods: A total of 72 fecal samples were examined by salt flotation and the modified McMaster fecal egg count technique to morphologically identify nematodes eggs and determine their egg per gram (EPG) outputs.

Results: Out of a total of 72 (100%) donkeys sampled, 36 (50%) tested positive, but the prevalence of nematodes was independent of the age, sex, and breed of donkeys (p>0.05). Among the four species of nematodes identified in single and mixed infections, Strongylus spp. (27.8%) and Dictyocaulus arnfieldi (13.9%) were the most prevalent followed by Strongyloides westeri (5.6%) and Trichonema spp. (5.6%). Infected donkeys had moderate overall mean EPG (801.39±611.3) with no statistical differences between age groups and sexes (p>0.05), but means of EPG were significantly higher (p<0.05) in Duni (1026.92±719.55) than Idabari (673.91±514.75). Light EPG count was recorded among 63.9% of infected donkeys, while 16.7% and 19.4% had moderate and severe infections, respectively.

Conclusion: The prevalence and importance of equine nematodes were discussed in connection to their epidemiology and control. Furthermore, the preponderance of light infection may suggest that donkeys in this environment developed resistance to nematode infection and are potential reservoirs for other equines.
