The frequently detected defects were scratch (83.33%) followed by wound (50%) and least detected defects were putrification (1.67%) and brand mark (1.67%). From the total defects the proportion of demodectic mange was 20%. Out of the 60 skins 58 of them were encountered two and more than two defects. Those skins with more than two defects and above have been graded under 6 and above. According to Sheba Leather Industry guidelines, those skins graded under grades greater than 7 are rejected. Therefore, out of 60 goat skins 26 (43.3%) of them has been rejected. Most of the rejected skins were affected with at least two defects and above.Conclusions: In conclusion, around 12 major defects that have high impact on the quality of skin have been identified. Therefore, to minimize the defects of the skin extension service should be promoted to increase the public and butchers awareness and collaborative work with stakeholders should be enhanced.
