The objective of this study was to evaluate the nutritional quality twenty-nine cultivars sugarcane. design completely randomized, with treatments (cultivars) and three replicates. evaluations were performed at 540 days after planting during phenological stage maturation sugar cane. Stalk length, number nodes per plant, internodes length stalk diameter evaluated. samples crushed, pre-dried ground for achievement chemical analysis, carbohydrate fractionation in vitro digestibility dry matter (DM), organic (OM) neutral detergent fiber (NDF). Data analyzed by analysis variance posteriorly submitted Scott-Knott test 5% probability. Regarding biometric measurements differed (P<0.05) but there no difference (P>0.05) as well average internode diameter. content DM, OM, protein, ether extract, NDF acid showed differences between evaluated (P<0.05). Carbohydrate also (P <0.05), being that RB86 7515, RB92 806 RB03 6091 presented high fraction rapidly degradable carbohydrates. highest values DM OM occurred 579 Considering variables analyzed, 6091, 7515 greater concentration carbohydrates demonstrating potential use ruminant feeding.
