Abstract

This paper presents dynamics and parameters of in vitro gas production of integral forage of two new cultivars of sugarcane (Saccharum spp., C97-366 and C99-374.), selected for forage, and compared with a control (My5514 commercial variety). Integral forage samples were analyzed, according to a completely randomized design, at eleven months of regrowth with the use of the technique of in vitro gas
production. New varieties showed higher gas production (P <0.05) than My5514 at 48, 72 and 96 h of incubation, without significant differences among them. Gas production parameters, lag phase and gas production potential (b) ranged from 2.48 to 3.27 h and 32.7 to 36.6 mL, respectively. Gas production speed (c) ranged from
0,023- 0,024 h-1. The two new cultivars had generally better in vitro digestibility than the control.
Key words: cultivar selection, sugarcane, digestibility
