Effect of harvesting stage on the nutritive value and forage performance of whole plant sugarcane

In order to evaluate some chemical composition of whole sugar cane at different vegetation stages, in a complete randomized design with two varieties the sugar cane early maturity and late maturity. Two fields of from two varieties of sugar cane were selected the sampling of roughage was done for 7 month. Treatments were 14 sample of roughage for a variety of sugar cane. For each sampling roughage, amount of DM, CP, ASH, NDF, ADF, DCH, ADL, CEL and HCEL for each variety of sugar can were calculated. Experiment indicated that, DM and DCH was increase with up age of sugar cane, and were significant varied among the treatments for two varieties of sugar cane. But amount of CP, ASH, ADF, NDF and HCEL in the time of experiment were decrease, and were significant different between the treatments for two varieties of sugar cane. The amount of ADL with age increase, were increase but were not process of specific, and different of between the treatments were significant for two varieties.
