This study was conducted to estimate the effect of natural pastures grazing conditions on Sudan Desert Sheep Skin\leather quality. Five Sudan desert sheep breeds aged 1- 1.2 years old were used in this experiment. One hundred and fifty (150) pieces of fresh skins from Five (5) non-castrated male of Sudan desert sheep breeds which bring from different geographical area from west Sudan (Kordofan state) and east Sudan (Gezira and Butana). Sheep were divided in two groups according to geographical zone. 15 pieces of sheep skins for each breed were selected from animals grazed at poor pasture areas and similar number were obtained from animals grazed in enriched pasture areas, according to pasture measurements records at each breed locations. The results revealed that, fresh skin weight and Leather cracking load were significantly affected (P ? 0.05) by pasture quality. Leather elongation, Tensile strength kg/cm2, Thickness values and Flexibility values were not statistically (P ? 0.05) affected by pastures quality. Moisture content of Sudan desert sheep leather values were significantly affected by pasture condition, with highest values of leather moisture content on Shugor sheep (group one) either on enriches and poor nutrition samples, and lowest values were in Kabashi and Hamari (group two) on poor pastures level. There were no significant effect of pasture quality on chemical characteristic (fat, ash and chrome oxide contents) on leather quality .The high values on fat content was in Shugor, Watish (group one) and Kabashi(group two) in both enrich and poor pastures levels. While the lowest fat contents were in Dubasi (group one) and Hamari (group two) sub-types on poor levels of pastures.
