Arab, H | Mehennaoui, S
The nutritive value of arid browse collected from South-East of Algeria at Biskra was studied on the basis of their chemical composition: dry matter (DM), organic matter (OM), ash, crude protein (CP), ether extract (EE), fiber: NDF, ADF, ADL and acid insoluble ash (ASHINS), Ca, P, Na, K, Mg, Cu, Zn and Mn. The browse species evaluated were the herbaceous Cynodon dactylon, Cyperus conglomeratus and the tree fodder Tamarix africana. Dry matter ranged from 253 to 509 g per kg fresh matter. The OM, CP, NDF and ADF contents in all plants ranged from 830 to 867, 110 to 143, 451 to 710, and 271 to 387 g per kg DM respectively. Acid insoluble ash and ADL levels were high in C. dactylon: 74 and 111g per kg DM respectively. Minerals contents in all plants varied widely. Macro minerals were present in sufficient concentrations to meet ruminant’s requirement. Trace minerals levels were marginal in terms of requirements. C. conglomeratus had a high Mn level (187 mg per kg DM).
