| dc.description.abstract | A cross-sectional study was conducted from October 2013 to May 2014 with the objectives to estimate the prevalence of ectoparasites of sheep in ectoparasites controlled and uncontrolled area, assess major risk factors as well as evaluate effect of ectoparasites on livelihood of farmer in ectoparasites controlled and uncontrolled areas of Arsi Zone, Oromiya Region. A total of 969 sheep (646 sheep from controlled area and 323 sheep from uncontrolled area) were examined for presence of ectoparasites. Accordingly, from controlled area 371 (57.43%) and from uncontrolled area 285 (88.24%) were infested with one or more ectoparasites. The ectoparasites identified from controlled area were B. ovis 48.9%, Linognathus spp 0.93%, sheep keds 7.4%, 2.32% B(R). decoloratus, 1.46% A. variegatum, 1.08 % A. gemma, 4.59% R. evertsi evertsi, and 0.31% mixed tick infestation and 12.5% mixed infestation. The ectoparasites identified from uncontrolled area were B. ovis 81.4%, Linognathus spp 0.9%, 1.79% B(R). decoloratus, 2.62% A. variegatum, 9.29% R. evertsi evertsi, 4.3% mixed tick infestation and 32.2% mixed infestation. The risk of ectoparasite infestation in sheep of uncontrolled area were 5.644 times higher than controlled area sheep (OR=5.644, p=.000). Significantly higher prevalence of lice, tick and keds infestation in the uncontrolled area than the controlled area was recorded. The risk of lice, keds and tick infestations in uncontrolled area was 7.061, 3.836 and 2.074 times higher than controlled area respectively. Age and management related variation was not observed in the prevalence of ectoparasite in both controlled and uncontrolled area. Significantly (OR=0.455, p=0.000) higher prevalence of overall ectoparasite infestation in the female sheep of controlled area than the male was observed. Female sheep in controlled area were 1.129 times at higher risk for lice infestation than male. Significantly higher prevalence of keds in controlled (OR=0.081, p=0.000) and in uncontrolled area (OR=0.715, p=0.000) on wooly than hairy sheep was recorded. The logistic regression results showed significant higher prevalence of tick infestations in female sheep (OR=1.861, p=0.000) and poor body condition sheep (OR= 0.478, p=0.015) of uncontrolled area. Female sheep and poor body condition sheep of uncontrolled area were 1.861 and 0.478 times at higher risk for tick infestation than male and good body condition sheep respectively. Favorable climatic x conditions, poor husbandry and animal management, lack of awareness by farmers, and weak animal health extension services are believed to have contributed for widespread distribution and occurrences of ectoparasites. Higher prevalence of ectoparasites observed in the controlled area put under question the effectiveness of ectoparasites control in selected districts of Oromiya Region. The growing threat of ectoparasites to small ruminant production and the tanning industry needs well-coordinated, appropriate and urgent control intervention.
