                                                        ABSTRACT: Nine samples of range herbage species were collected within the grazing season using 0.5 × 0.5 m quadrate as from three weeks initial pasture growth established in June across throughout up to December (two seasons), to examine the effects of age on the trend of some chemical compositions and energy changes. Analysis of variance indicated that the chemical composition of grassland from 3 weeks of age, to 12 weeks of age across to 27 weeks of age was affected by the grass age, where the metabolizable energy contents were 15.85, 13.11 and 12.36 MJ/Kg/DM respectively. Hemi-celluloses and cellulose content showed a significant difference increase (P
