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.

Abstract-This study was conducted in Sulaimani governorate in order to identify the biological control of some Ixodidae genera among different flocks of cattle, sheep and goats. Four genera of Ixodidae; Boophilus spp, Hyalomma spp., Rhipicephalus spp. and Haemaphysalis spp., were identified in these infested animals. According to chi-square test, the highest distribution of Boophulis spp., was recorded in cattle (56.51%), and the highest distribution of Hyalomma spp., (49.82%) and Rhipicephalus spp., (28.16%) which were in sheep. The highest number of Haemophasylas spp., was obtained from goats (6.67%), whereas the lowest number of this genus (2.88% and 2.89%) was collected from cattle and sheep respectively. The toxicity of Sorghum bicolor seed extract was tested against the more distributed Ixodidae genera (Boophilus spp. and Hyalomma spp.) by immersion method on mature ticks, four concentrations (23.2, 17.4, 11.6 and 5.8 mg/dl), in addition to the control treatment (0 mg/dl) of the seed were used to evaluate the engorged females in vitro. The results showed that 100% of absolute cumulative mortality of Boophilus spp., was gain after 72 hr by 23.2 mg/dl extract concentration, followed by 17.4 mg/dl which gave 90% mortality, whereas 100% absolute cumulative mortality for Hyalomma spp., was obtained by 23.2 mg/dl extract concentration after 48 hr, followed by 17.4, 11.6 and 5.8 mg/dl concentration that gave 90%, 80% and 40% mortality after 72 hr.Index Terms-Boophilus spp., Hyalomma spp., Sorghum bicolor seed extract

In this study isolated 100 adult female of local black goat (Capra hircus) examined in spring and fall season for Tick and Lice investigations, then divided into two groups: 50 infested goats with ectoparasite and 50 non-infested goats. Three species of ticks (Rhipicephalus sanguinus, R. turanicus and R. bursa) and one species of lice (Bovicola caprae) were observed. Biochemical values (serum proteins and some trace elements) analyzed, in infested goats emerges decline in serum protein value 7.12±0.08 µg/dl, albumin value 4.12±0.03 µg/dl and increase of globulin value 3.04±0.09 µg/dl, in serum protein and globulin values shows not significance differences, while described highly significance differences in albumin value at p≤0.01, when compared to control goats. In trace elements decline of zinc level 48.97±1.20 µg/dl and copper level 114.15±3.75 µg/dl levels with a highly significant differences at p≤0.01 in infested goats when compare to control goats. It is observed that mixed infestation has much effects than tick or lice infestation on goats, which led to reduction in serum protein value 6.89±0.20 µg/dl, albumin value 4.11±0.09 µg/dl and raise in globulin value 3.10±0.11 µg/dl without any significance differences, also noticed insignificant declines in zinc level 45.67±2.40 µg/dl, while decrease in copper level 99.33±9.86 µg/dl significantly at p≤0.05.

Rhipicephalus (Boophilus) annulatus is considered as one of the most widespread tick species of the world on several host including cattle. The current study has been conducted to evaluated infestation ability of larval R. annulatus on chicken growth and development, Indicated very few larvae quested or fed on indigenous adult chickens when comparison with the number of larvae which used in this study, and that the larval and nymph feeding period of these ticks was very long. The number of larvae feeding shows in hollows wings, while the number of feeding nymph investigate on head, wings and above of thigh, both larvae and nymph described on the same individual adult chicken, the engorged adult female not observed while the adult male notice on chickens. Designated the weight of feeding larvae and nymphs stage is 0.32±0.04 mg and nymph’s 2.73±1.22 mg. The weight of larvae and nymph stage under mattress and feeder’s chicken 0.27±0.21 and 2.52±1.75 mg respectively, shows not significantly when compared between the weight of feeding on chickens and the weight under mattress and feeder’s chicken by larvae and nymphs stage at (P < 0.05) values according chi-square. Experimental study shows not transmissions pathogens from incubating larvae, which got from engorged female infested with Babesia spp., to adult chickens when examined their blood by Giemsa stain.
