Through this research work, evaluating the chemical-bromatologic composition of in natura sugar cane as related to hydrolysis with whitewash. The work was conducted in the Forage Culture Sector of the Animal Science College at José do Rosário Vellano University (UNIFENAS), campus of Alfenas (MG). The experimental design utilized was the completely randomized in a factorial arrangement 4x5, four doses of whitewash were studied (0.0; 0.5; 1.0 and 2.0% on the basis of natural matter) in five times aerobic exposure (0, 6, 12, 24 and 48 hours), with four replicates. The addition of whitewash to sugar cane promoted lower temperatures till 12 hours of storage, from this point on, there no further effects of whitewash upon temperature control. The content of dry matter and ashes increased linearly with addition of whitewash, while protein content decreased. Whitewash promote no fall in the contents of water-neutral detergent-insoluble fiber and lignin, nevertheless, the contents of acid detergent insoluble fiber decreased, with more forceful when using 0.5 and 2.0% of whitewash. The use of whitewash in the hydrolysis of sugar cane alters the chemical bromatologic composition, however, the use of this additive is unjustified, because is not effect positive on the fiber content. The sugar cane in natura and hydrolyzed present the best composition immediately after the desintegration.
