Abstract

The objective was to evaluate the effect and the best level of crude glycerin inclusion in sugarcane ensilage on the parameters of the chemical composition and fermentative losses. The treatments consisted of five levels of inclusion of crude glycerin (0, 1, 5, 10 and 15% inclusion in natural matter) during sugarcane silage. A completely randomized design was used, with five treatments with six replicates. The silages were manufactured in PVC pipes. The utilization of crude glycerin increased on average 16.3; 54.1; 24.0 and 17.8% of the dry matter, ether extract, non- fibrous carbohydrates and total digestible nutrients of sugarcane silage, respectively, in relation to silage control sugarcane (P‰¤0.05). Increments of 0.56% and 0.18% in the dry matter and ether extract were found in sugarcane silages for each 1% inclusion of glycerin, respectively. Among the inclusion levels, the addition of each percentage unit of glycerin in the natural material reduced by 2.3% and 2.1% to the effluent losses and gases losses, respectively. The addition of 15% of crude glycerin in sugarcane ensilage improves the chemical composition and reduces fermentation losses.
