Leather quality of some Sudan desert sheep and goats
Abstract
This trial is aimed to study leather properties that produced from Sudan Desert sheep and goats in relation to breed type and age category. Thirty pieces of fresh sheep and goats skins were collected randomly (15 for each) during January 2015. The collected skins were tanned and the produced leather properties were studied. The Statistix 8 program for variance analysis was used for data analysis. The study samples were taken according to the Complete Randomized Design. Sheep leather results revealed that, lamb's skin was significantly (P ≥ 0.05) produced better quality leather than ram's and ewe's skins in elongation (%), tensile strength (kg/cm2), cracking load (kg), thickness (mm), tear load (kg/cm), flexibility and moisture%. While it was yielded leather with the same characteristics to ram's and ewe's leather in Ash (%), fat (%) and chrome (%). Leather properties [elongation (%), tensile strength (kg/cm2), cracking load (kg), tear load (kg/cm), flexibility and Ash (%)] were significantly (P ≥ 0.05) affected by breed variation. On the other hand thickness (mm), moisture (%), fat (%) and chrome (%) were not significantly (P ≥ 0.05) affected by breed. Ram's skin was produced better quality leather than ewe's skins. Goat's leather results revealed that, kid goat's skin was significantly (P ≥ 0.05) produced better quality leather than bucks and doe's skin in tensile strength (kg/cm2), cracking load (kg), thickness (mm), tear load (kg/cm) and flexibility degree. But kids and buck's skins were produced the same quality leather in elongation % and moisture% with significant variation (P ≥ 0.05) to doe's leather. Kid's skin yields leather with the same characteristics to buck's and doe's leather in Ash (%), fat (%) and chrome (%). Generally Desert goats produce slightly better quality leather than Nubian goats. Leather prosperities [cracking load (kg), tear load (kg/cm), and Ash (%)] were significantly (P ≥ 0.05) affected by breed variation. Elongation (%), tensile strength (kg/cm2), thickness (mm), moisture (%), fat (%), flexibility and chrome% were not significantly (P ≥ 0.05) affected by goats breed.
