Feedlot performance and carcass quality were investigated on Sudan Desert sheep raised under irrigated conditions in the Gezira area. Average daily gain over the fattening period of 56 days in the feedlot was 237.0±2.0 g. Single born lambs grew faster than twin-born lambs (p
Young Watish lambs grazing berseem grow at 148 and 105 g/day for males & females respectively, over a 20-week period. The provision of various concentrate supplements marginally increased live-weight gains but this practice was not recommended as being of economic value. Hot carcass weight of you...
