The use of cassava (Manihot esculenta Crantz) in animal feed is a way to take advantage of post-harvest residues, contributing to the sustainability of the production system by minimizing production costs by replacing high-cost conventional ingredients, such as corn. The objective was to evaluate the fermentative characteristics and the chemical composition of the aerial part silage and cassava roots according to the aerial part and root harvest time and the storage period. The experiment will be conducted under field conditions at the Escola Escola de Igarapé-açu (FEIgA) of the Federal Rural University of the Amazon (UFRA), located in the municipality of Igarapé-açu, Pará. A completely randomized design will be used with six harvest seasons. aerial part (6, 7, 8, 9, 10 and 11 months after planting) and three storage periods (3, 30 and 90 days). From the six months after planting, the aerial part (50 cm from the soil) and the cassava root for silage will be collected at intervals of 30 days in all plots until the last harvest season. In all samples (aerial part and root in natura and the silage), determination of the chemical composition, fermentative characteristics, microbiological population, pH will be carried out in order to characterize the silage of both the aerial part and the cassava root.
