Perdas fermentativas, composição química, estabilidade aeróbia e digestibilidade aparente de silagem de cana-de-açúcar com aditivos químico e microbiano
2009
The objective of this work was to evaluate the influence addition whitewash (CaO) and Lactobacillus buchneri in fermentation losses, nutritional value, aerobic stability and apparent digestibility of sugarcane (Saccharum officinarum) silages. A first experiment evaluated fermentation losses, pH and temperature values, chemical composition and in vitro dry matter digestibility of sugarcane silages with or without bacterial inoculants (L. buchneri) or CaO. A second experiment evaluated intake and apparent digestibility of sugarcane silage with the same additives to sheep. The additives did not reduce silage losses, and silages with CaO presented greater effluent losses. The intake of silage with inoculant was lower than of silage with CaO and in natura sugarcane. Dry matter apparent digestibility of CaO silage was lower than that of in natura sugarcane and of silage with inoculant. Greater values were observed in ether extract for silage treated with CaO when compared to in natura sugarcane. Total digestible nutrients values of in natura sugarcane and of silage with inoculant or CaO were 61.2, 54.1, and 51.7%, respectively. Regardless of the additive, sugarcane ensilage results in nutrient loss and in reduced digestibility.
