Abstract
This research was carried out to detect the effect of concentrate supplementation on the performance and carcass characteristics of natural grazing Sudanese desert lambs. Twenty one (one year old) male lambs were used for 56 days. These Lambs were divided into three homogenous groups. The three lamb groups grazed on natural pasture for about 8 hours daily. After grazing period the first group (C1) received zero concentrate, the second group (C2) received 200 g/head/day concentrate and the third group (C3) received 400 g/ head/day concentrate. At the end of the feeding trials, the animals were slaughtered for carcass analysis. Final live weights did not differ significantly between treatment groups although lambs fed concentrate level 200g and 400g were heavier than the group that not supplemented concentrate. The daily weight gain was increased with increasing concentrate level. Empty body weight was differed in lambs fed on different levels. Dressing percentage of lambs fed 200g and 400g concentrate were similar and higher than in lambs fed on pasture alone. Weights of the head, blood, feet, lungs, heart, liver, spleen, rumen, gut, mesenteric fat and testicles did not differ, however, weights of skin, tail and kidney differed significantly. The results showed that concentrate supplementation is necessary to improve growth performance.
