Survey on Mite Infestations in Small Ruminants in Kindo Didaye District, Wolaita zone, Southern Ethiopia

Background: Mange is a parasitic skin disease caused by microscopic mites that feed on the skin of small ruminants and affect animal productivity. Methods: A study was carried out to determine the prevalence and possible risk factors for mite infestation in small ruminants in Kindo Didaye district, Wolaita zone, southern Ethiopia. Skin scraping samples were collected from 384 small ruminants (196 goats and 188 sheep) for the identification of mite species following the standard parasitological protocol. Results: Of the 384 examined animals, 6.25% of sheep and goats were infested with different mite species, namely, Sarcoptes (3.67%), Demodex (1.54%), and mixed infestation of Sarcoptes and Demodex (1.04%). A relatively higher prevalence of mite infestation occurred in goats (7.14%) than in sheep (5.3%), and the highest prevalence of lesions of mange mites was recorded in the neck region (3.13%). The multivariate analysis of factors revealed that only BCS and herd size have a significant role in mite infestation of small ruminants. In addition, the correlation analysis of mite infestation with factors revealed that herd size ( r = .106), sex (.0434), and body condition score ( r = .104) had a positive correlation with mite infestation. Conclusion: Mites are among the most important health constraints of sheep and goats in the study area, requiring immediate attention and control interventions. Moreover, further epidemiological investigations that consider agroecology and other nonhost-related risk factors should be carried out for the appropriate control of mange mites.
