Qualidade da silagem de resíduo agroindustrial de abacaxi utilizando aditivos sequestrantes de umidade

Abstract

The silage has the objective of enabling the feeding of animals in times of food scarcity, since there is the availability and possibility of using pineapple agro-industrial residues for animal consumption together with the addition of additives. The objective of this work was to evaluate sequestering additives in the bromatological and fermentative characteristics of pineapple waste silages. A completely randomized design was used with four treatments and five replications where: T1 – Treatment without inclusion of bran, only pineapple agro-industrial residue; T2 Treatment with 20% inclusion of corn bran (based on natural matter); T3 – Treatment with 20% inclusion of wheat bran (based on natural matter) and T4 – Treatment with 20% inclusion of rice bran (based on natural matter). The chemical composition - bromatological and dry matter recovery of the silages were evaluated, along with the sensory analysis for nutritional and sanitary characteristics, where the silages were classified as "good to very good", with the exception of treatment 4 with the addition of rice bran where it was classified as "satisfactory". The addition of bran influenced the bromatological composition of the pineapple residue silages, providing higher DM and TDN contents.
