Abstract: | There is need to evaluate the locally available animal feeds in Nigeria so as to be able to combine them in acceptable proportions
to the animals to achieve the desired growth rate. The technique of particle-induced X-ray emission (PIXE) was employed for
the evaluation of these locally available animal feeds, which include Panicum maximum (Guinea grass), Cynodon plectostachyum (grass), Leucaena leucephala (legume), Calopogonium mucunoides (legume), Gliricidia sepium (legume), Euphorbia polychrome (legume), Pueraria phaseloides (legume), and Centrosema pubescens (legume). The proton beam delivered by the 2.5-MV AN 2000 Van de Graaff accelerator at the International Centre for Theoretical
Physics Laboratori Nazionali di Legnaro (LNL), Padova, Italy was used for the PIXE measurements. Twenty-one different elements
were detected at various concentrations and their nutritional effects on different animals are discussed. |
