Popis:	This study assessed the concentrations of crude protein (CP) and minerals in tef ( Eragrostis tef ) and grass pea ( Lathyrus sativus ) residues, noug seedcake ( Guizotia abyssinica ) and grass pea grain produced on Vertisols of the Ethiopian highland. Soil and feed N and minerals were determined from samples obtained from tef and grass pea crop fields as well as oil extracting plants. The concentration of Ca (16 g/kg), Na (274 mg/kg) ( P P P 0.05). It was concluded that the observed CP and mineral concentration differences between the examined feed sources can be exploited to ensure optimum supply of CP and most minerals, but Na and Cu deficiencies would likely limit production of animals relying on these feeds.
