This trial was designed to study the effect of intake of ailanto (Ailanthus excelsa) fodder on dry matter intake, nutrients digestibility and performance of Sudanese Desert lambs. Twelve heads of lambs, six months old and weighing (17+ 0.37) kg were divided into three groups with four heads each. They were vaccinated and dosed with broad-spectrum antihelmentics (ivermectin) for treatment against internal and external parasites and ear- tagged to facilitate identification during treatments. The Ailanthus excelsa, fodder, groundnut haulms and the natural grazing was fed to group I, II and III, respectively. Water was provided continuously and feed intake was monitored daily. The feed samples were analyzed and apparent nutrients digestibility was determined by total feces collection method. This complete randomized design data was analyzed via analysis of variance and differences among means were detected using Least Significant Difference test (LSD). Feed intake was significantly (P<0.05) higher for group 1 followed by the group on groundnut haulms and finally the group on the natural grazing where the amounts consumed was 865.90, 850 and 800 grams per day. Dry matter digestibility was the highest in the group on Ailanthus excelsa fodder, followed by groundnut haulms ​​and the lowest for those on natural grazing where DMD was 75.67, 67.45, and 56.45%, organic matter digestibility 78.61, 69.65 and 57.55%. Body weight changes indicated that they were higher in the Ailanthus excelsa fodder group and then in the groundnut haulms group and lower in the natural grazing group. The highest daily weight gain (60 grams) was obtained when animals fed on Ailanthus excelsa fodder compared to 45 grams and 40 grams a day for the group fed groundnut haulms and natural grazing, respectively.
