A Comparative Analysis of Nutrients and Mineral Elements Content of Andropogon gayanus Kunth and Pennisetum pedicellatum Trin

Comparative studies on the nutrients and mineral elements content of the two grass species was conducted at Gangam Rangeland, Shagari L.G.A., Sokoto state. Sokoto lies on latitude 12.000 and 13.600N and longitude 4.800 and 6.500E and altitude 350m above sea level. The result show that P. pedicellatum had high crude protein (Cp) ad crude fibre (Cf) content than A. gayanus. The high Cp content was attributed to its leafy nature (having abundant leaves) as Cp is more concentrated in leaves, whereas the high Cf content was possibly due to its stemmy nature particularly at the end of the growing period. However, in terms of Ether extract (Ee) andAsh content, A. gayanus had more. The high Ash content was probably as a result of high mineral elements content of the grass species. On the other hand, A. gayanus had high Phosphorus (P), Potassium (K), Magnesium (Mg), Iron (Fe), Copper (Cu) and Zinc (Zn) content, while P. pedicellatum has high Calcium (Ca) and Sodium (Na) content. The high mineral elements content of A. gayanus made the grass more useful for grazing and feeding of livestock. The high Ca content of P. pedicellatum may account for its high Cf content as Ca forms structural components of cell walls and membranes.Keywords: Nutrients content, Andropogon gayanus, Pennisetum pedicellatum, Shagari LGA
