An Application of Pareto Analysis and Cause-and-Effect Diagram in Raw Hide and Skin Defects Minimization in Ethiopia: Selected Case Dire Dawa City Slaughterhouse (Ethiopia)

Abstract

According to the reports of CSA (Central Statistics Agency) 2020 Ethiopia is the 10th in the world and 1st in Africa by cattle production. Furthermore, the leather sector is the priority sector in Ethiopia. Leather industries are facing challenges in improving productivity and quality in the competitive market nowadays. The input materials for leather industries are goat and sheep skin, and cattle hide in Ethiopia. However, there are raw hide and skin defects due to preslaughter, during slaughter and post-slaughter process. This study focuses on the minimization of the major defects in preslaughter and during the slaughter of raw hide and skin process by application of Pareto analysis and fishbone diagram in Ethiopia in the case of Dire Dawa city. The Pareto analysis reveals that priority should be given to solving the problems of pre-slaughter and during-slaughter defects of raw hide and skin. Based on cause-and-effect diagram analysis, the main causes are: machine, material, environment, man, measures and management, root causes, heated metal shape for brand mark, during diseases different action is taken, hit animal using different steel, grass used for food, animals home making material, drinking water, stick, topography, hot area, old area, lack of awareness about hide and skin outputs, traditional methods of water in forage for the animals during farming, traditional methods used for medications for raw hide and defects identified. Finally, a few recommendations are made to reduce raw hide and skin defects.
