Qualidade da silagem do resíduo agroindustrial de acerola com três tipos de farelos: Farelo de milho, de trigo e de arroz

Abstract

The objective of this work was to evaluate the sensory quality, bromatological composition and dry matter recovery of acerola residue silage with moisture sequestrant additives: corn, rice and wheat bran. A completely randomized experimental design was used, with four treatments and five replications, respectively: T1- acerola residue silage; T2- acerola residue silage with 20% of corn bran; T3- acerola residue silage with 20% rice bran; T4- Acerola residue silage with 20% of wheat bran. The means of the variables were subjected to analysis of variance and compared using the Tukey test. The acerola residues were homogenized in a container and compacted manually with wooden sockets in PVC laboratory silos, then closed and weighed. At 30 days after ensiling, the silos were again weighed and opened, in order to evaluate dry matter and recovery of dry matter, after being opened, the first 5cm of silages were discarded, to later carry out the evaluations: sensory analysis for sanitary and nutritional aspects, determination of dry matter, mineral and organic, and neutral and acid detergent fiber. The good quality of the silage was confirmed through sensory analysis. Therefore, silages using moisturesequestering additives, in addition to demonstrating good fermentation, enabled an increase in dry matter and CP in all treatments, indicating good nutritional value. However, the high levels of NDF can make the consumption of acerola waste silage unfeasible.
