The study was carried out through the clinical examination on the skins of sheep and goats to identify the quality and processed in the tanneries. Parasitic skin diseases caused by ectoparasites such as mange mites, lice, and ticks are among these threats resulting in a serious economic loss to the tanning industry and the country as a whole. Out of 38066 sheep and 9889 goats examined in Sulaimani slaughterhouse in spring season 2017, shows statistically significant P<0.05 between sheep and goats prevalence; 9.35% and 7.43% respectively with one or more ectoparasites. Three different of ectoparasites were infested in both sheep and goats namely; hard tick, lice and mite. Five species of hard tick (Ixodidae) were identified in sheep and goats as follows; Boophilus spp 3.68% and 14.16%, Rhipicephalus sanguineous 12.47% and 28.63%, Rhipicephalus turanicus 7.50% and 15.96%, Hyalomma a. anatolicum 11.90% and 31.30%, Hyalomma marginatum 9.26% and 9.95%) respectively. Two species of lice were identified in sheep namely, Damalinia ovis 17.74% and Linognathus stenopsis 13.63%, and D. caprae 10.97% and L. stenopsis 6.22% on goats. Highly infested were identified with mite on sheep include Psarcoptic scabiei 13.83% and Psoroptic ovies 9.98%, while only one species founded in this study in goats namely, Psarcoptic scabiei 22.79%. The overall number of skins refused to tanning industry 164 (4.61%) in sheep and 116 (15.78%) in goat. The difference in the prevalence of skin disease infestation between refused skin in both sheep and goats were statistically significant in ruminants (P<0.05). This paper deals with major skin defects in occurrence by ectoparasites sheep and goats in Sulaimani province.

Thirty herds comprising four hundred and fifty camels (Camelus dromedarius ) ranging from 5 months to 17 years of age were subjected to external examination of ectoparasites (ticks, mange mites and flies) during November 2010 to July 2011 at Cholistan, Bahawalpur, Pakistan. An overall prevalence of Ectoparasites was 55.55%. Ticks were the most frequent ectoparasites harboring on dromedaries. The ticks in order of their infestations were; Rhipicephalus spp (28.95%) Hyalomma dromedarii (26.48%), Dermacentor spp (18.29%) H. anatolicum (12.47%), H. marginatum (6.69%), Ornithodoros spp. (4.89%) and Amblyomma variegatum (2.20%). The Sarcoptes scabiei var. cameli (42.22%) was identified as most dominant mange mite. 40.88% camels were infested with two species of dipterans i.e.; Chrysomyia spp. (10%) and Wohlfahrtia magnifica (16.67%) which are most frequently causing preputial and vaginal myiasis. Cephalopina titilator fly (1.11%) was found to cause camel nasal myiasis. The district wise prevalence was as Rahim Yar Khan (60.87%), followed by Bahawalnagar (49.75%) and Bahawalpur (41.05%). The tick load per animal was higher during summer especially in July (64.52%) followed by the lowest ticks load during December (25.58%).The infestation of ectoparasites was higher (69.53%) in camels ranging the age from 5-7 year however the lowest infestation (23.08%) was noted in camels less than one year of age.
