Abstract

The objective of this study was to evaluate the chemical composition of tomato bagasse silage containing increasing inclusion levels of semi-purified glycerin. The experiment was conducted as a completely randomized design consisting of five treatments and four replicates, with exclusive tomatog bagasse silage and four inclusion levels of semi-purified glycerin (7.5%, 15%, 22.5% and 30% added based on natural matter). The inclusion of glycerin during ensiling increased dry matter content and linearly reduced silage pH, but did not alter ammoniacal nitrogen. Crude protein and neutral/acid detergent fiber decreased linearly, while in situ dry matter digestibility increased in a linear manner with the inclusion of glycerin in tomato bagasse silage. The inclusion of up to 30% semi-purified glycerin is suitable for ensiling tomato bagasse since it improves the fermentation quality and engery value of the silage.
