This study was conducted to determine the prevalence and type of ectoparasites and to identify risk factors associated with ectoparasite infestations in small ruminants in and around Sekela, Northwest Ethiopia. Clinical examination and laboratory analysis were made on 304 sheep and 96 goats. The collected raw data were analyzed using χ (2)-test. Out of the 400 sampled animals, 182 (45.5%) were infested with one or more ectoparasites. The prevalent ectoparasites observed were lice, ticks, Ctenocephalides species, Melophagus ovinus, and Demodex species. The infestation rates of ectoparasites with age and sex were significantly varied (P < 0.05) in sheep but not in goats (P > 0.05). Body condition score was not significantly associated (P > 0.05) with ectoparasites infestation in both sheep and goats. In our attempt, only two cases due to Demodex species were recorded in sheep. In conclusion, the prevalence of ectoparasites in the present study was high and this could affect the wellbeing and productivity of small ruminants. Therefore, to reduce ectoparasites prevalence and impact on the productivity and health status, planning of integrated control measures with sustainable veterinary services aiming at creating awareness about the importance and control of ectoparasites for livestock owners is required.
