【 摘 要 】

The contents of phosphorous (P),calcium (Ca),sulphur (S), manganese (Mg),sodium (Na),potassium (K), iron (Fe), and copper (Cu), in graminaceae and legumes used for ruminant nutrition in the city of Adama, Eth i-opia, were determined. The samples were taken at random, from grazing areas near the city, and in the food market for these animals. The Molibdovanate method was used to determine P ; Ca,Mg and Cu were determined by the atomic adsorption spectroscopic met hod with flame; Na and K were determined by flame photo-metry; and S, by the turbidimetric method. The values were compared with the values reported forthese animal requirements. Deficiencies of Cu, P and Nawerefound in all the samples analyzed. King Grass, wheat andteff stalks, important sources of nutrients du ring the dry season, were the scarcest. Statistics (P < 0.05) showed that, as a group, graminaceae were more mineral deficient than legumes. A study of certain mineral sources from the area is recommended for use as raw materials for salt production.
