Abstract

SIQUEIRA, Gustavo Rezende et al. Chemical and bacterial additives association on the sugar cane ensilage. R. Bras. Zootec. [online]. 2007, vol.36, n.4, pp. 789-798. ISSN 1806-9290.  http://dx.doi.org/10.1590/S1516-35982007000400006.

This trial was conducted to evaluate the sugar cane silage treated with chemical additive (urea-1.5%, sodium benzoate-0.1%, and sodium hydroxide-1.0%), associated with control, and two bacterial inoculants (Propionibacterium acidipropionici + Lactobacillus plantarum e Lactobacillus buchneri), in a factorial scheme (4 x 3), and three replications per treatment. It was evaluated the nutritive value of the sugar cane treated with different additive combinations, before and after ensilage. The association of the P. acidipropionici or L. buchneri with NaOH, compared to the control resulted in better preservation of DM (32.2 and 33.5%, compared to 27.4%, respectively), and preserved the NDF (53.4; 55.7% versus 75.3%), ADF (39.5, 44.3% versus 48.7%), lignin (6.6, 7.1% versus 8.1%), and NFC (33.8, 31.7% versus 14.9%), resulting in higher true in vitro DM digestibility (60.3, 63.2% versus 35.1%). The observed values could be associated to the yeast control due to the associative additive effects. In general, it is possible to conclude that sugar cane ensilage process require an efficient additive utilization.
