Evaluation of two varieties of sugar cane submitted to different storage times

Abstract

A study was carried out to investigate the effects of four different storage times on technology and bromatologic characteristics in two sugar cane varieties (CO 413 and RB 72 454). The varieties were cut and stored during zero, 1.5, 3.0 and 4.5 days. It was used a completely randomized design according to a 2 x 4 factorial scheme. The RB 72 454 variety showed better dry matter level than the CO 413 variety. The storage time increased (P < 0.01) the reducters sugar levels and decreased (P < 0.01) the crude protein levels. When they were stored during 4.5 days, a significative (P < 0.01) reduction of 14.66 and 4.04% in the levels of crude protein and gross energy, respectively, was observed.
