摘　　要：This study was carried out to assess the leaves and fruits of Grewia mollis, Grewia tenax and Grewia villosa for their potentials to produce high nutritive value fodder under semi-arid conditions. The experiment was conducted at the farm of the College of Natural Resources and Environmental Studies, University of Juba-Khartoum-Sudan. Randomized Complete Block design with three replications was used. Proximate analysis was carried to estimate nutritive value, and mineral contents of leaves, seeds and fruit pulp of the three species. Results indicated significant difference （P ≤ 0.05） in nutritive value of the leaves among the three species; dry matter, ash, and acid detergent factor （ADF） kg/ha, while no significant difference was observed among the species in crude protein （CP） and nutrient detergent factor （NDF） kg/ha. Mineral contents of the leaves of the three species showed variations among the species and seasons. Seeds and fruit pulp were found to have considerable levels of nutrients and mineral contents. The nutritive value of the three species was higher in the rainy season compared to the dry season. The results of this study indicate that the three species can be introduced as a source of fodder in animal production farms and silvopastural systems.
