- Abstract
This study aimed to evaluate the potential of Typha domingensis ("taboa") as an ingredient with different inclusion levels in sugar cane (Saccharum officinalis) silage, by the study of the fermentative parameters. The experiment was carried out as a completely randomized design with four treatments and six replicates. After 90 days, of the silos' opening , the levels of water soluble carbohydrates, ethanol, organic acids (lactic, acetic, propionic, butyric acid), crude protein (CP), mineral matter (MM), total digestible nutrients (TDN), in vitro organic matter digestibility by gas (IVDOM), pH and buffer capacity; and, the losses by gas, effluent and total of dry mater, density and dry matter recovery were estimated. Increasing levels of "taboa" reduced (P<0.05) silage density and increased the contents of CP, MM, TDN e IVDOM; although it has not been observed effect (P>0.05) on the loss and recovery of DM. Ethanol concentrations were influenced (P<0.05) by increment of "taboa" where reduction of 76.92% was observed, with 40% of "taboa" relative sugarcane silages exclusively. The inclusion of "taboa" increases the protein content and minerals, as well as TDN and IVDOM, also signifi cantly reduces ethanol production of sugarcane silages. The inclusion of taboa in the ensiling of sugar cane substantially improved fermentation characteristics and nutritional value of the silage mass.
