Abstract

The use of ensiled sugarcane has been increased lately in Brazil due to the benefits that this technique represents. The objective of this study was to evaluate the effects of chemical additives on the nutritive value of sugarcane silages. The trial was carried out in a completely randomized experimental design with four replicates per treatment. The following additives were applied onto the fresh forage before ensiling: L. buchneri, lime or limestone, 1.0 and 1.5% (wet basis) each, and gypsum 1.0% (wet basis), all of them diluted into 40 L of water per ton of fresh weight of forage. The analyzed variables were: ash, crude protein, neutral detergent fiber, acid detergent fiber and organic and dry matter digestibility. The addition of lime or limestone before ensiling produced silages with higher nutritive value compared to all other treatments, due to the increase of the ash content and dry matter and organic digestibility, and also by reducing the fiber content. The crude protein content range was similar to the values observed in the fresh forage. The treatments containing L. buchneri or gypsum were ineffective in improving the nutritive value of sugarcane silages and became similar to the control silages. Treatment containing lime or limestone improved the nutritive value of the sugarcane silage.
