Effects of Concentrate Supplementation on Skin Quality Attributes in Crossbred Sheep

Abstract

This study examined the effects of concentrate supplementation levels on skin quality in crossbred sheep (Awassi X Bonga; AB, Awassi X Washera; AW, and Dorper X Menz; DM). The lambs (44 in total) were randomly assigned to different breed and supplementation groups. They grazed on natural pasture and received 300, 600, or 900 grams of concentrate feed with 21% crude protein and 14 MJ/kg metabolizable energy. After 90 days, the animals were culled, and their skins were assessed. Higher concentrate supplementation (900 g) significantly improved skin weight, size, thickness, and tear load (p < 0.05). Moisture content, fat content, and hide substance percentage were not significantly affected by the supplementation level (p > 0.05). DM breed showed higher thickness, tear load, and moisture content for raw skin compared to AB and AW (p < 0.05). Skins from DM with 900 g supplementation exhibited superior quality. The study concluded that skins from different breeds with concentrate supplementation (300 to 900 g) showed improved leather production within acceptable standards. Further research is recommended for indigenous sheep breeds in different regions, considering crossbreeding levels.
