DIGESTIBILIDADE DA CANA-DE-ACÚCAR HIDROLISADA, IN NATURA E ENSILADA PARA BOVINOS

The objective of the present study was to determine in vitro dry matter ruminal digestibility (IVDMD), neutral detergent fiber (IVNDFD), acid detergent fiber (IVADFD) and lignin (IVLD) in two varieties of sugarcane (IAC 862480 and RB 835453), hidrolised with zero; 0.5 and 1.0% of the lime, during three hours, in natura and ensiled forms. The treatments with three replications, in scheme factorial design were applied. There was no influence of the different lime levels, but the digestibility in the 0; 0.5 and 1.0% of the lime were equal statistically (P>.05). The IVDMD, IVDFDN and IVDFDA were greated in IAC 862480 variety in the lime levels utilized. Despite the variation found in the digestibility of some components, both in natura with 0.5% and silagem with 1.0% of sugarcane are indicated in dairy and beef cattle feeding program. KEY WORDS: Bovine, calcium oxide (lime), ensilage, in vitro.
