A total of 120 sheep and 120 goat pelts with known infestation by ectoparasites and ectoparasite free control pelts were purchased and processed in Sheba tannery and the corresponding skin defects were analyzed. Accordingly, three groups of 40 sheep pelts each (one group infested with &lt;em&gt;M. ovinus&lt;/em&gt;, one group infested with&lt;em&gt; Damalina ovis&lt;/em&gt; and a control group of ectoparasite free sheep pelts) and three groups of 40 goat pelts each (one group infested with sarcoptic mange, one group infested with &lt;em&gt;Linognathus&lt;/em&gt; spp. and a control group of ectoparasite free goat pelts) were used. Defects observed at pickled stage include cockle, scratch, scar, technical defects due to flaying and old age. A strong association (P&amp;lt;0.001) was observed between cockle lesion and infestation of sheep pelts with &lt;em&gt;D. ovis&lt;/em&gt; and&lt;em&gt; Mellophagus ovinus&lt;/em&gt; and infestation of goat pelts with sarcoptic mange. Further more, the severity of infestation of sheep pelts with &lt;em&gt;M. ovinus&lt;/em&gt; and &lt;em&gt;D. ovis&lt;/em&gt; and infestation of goat pelts with sarcoptic mange were found to correlate significantly (P&amp;lt;0.001) with severity of cockle defect. Further investigation on 1000 pickled sheep and 1000 wet blue goat skins revealed that scratch defect was the dominant (43.4 % and 53 %), followed by cockle (35 % and 21.5 %), scar (7 % and 6.8 %) and knife cut (3.4 % and 6.2 %) in pickled sheep and wet blue goat skins, respectively. There was a significant difference (P&amp;lt;0.001) in proportion of cockle between pickled sheep and wet blue goat skins. In addition, a strong association (P&amp;lt;0.001) was observed between cockle and scratch, and cockle and scars on both pickled skins. The economic loss due to quality deterioration of exported skin in the study tannery was estimated to be 778,199.41 USD for pickled sheep and 247,677.61 USD for wet blue goat skins per annum. The growing threat of ectoparasites to small ruminant production and to the tanning industry needs well coordinated and urgent control intervention.&lt;/p&gt;
