SILAGEM DO RESÍDUO DE MILHO DOCE

Abstract

The experiment was conducted at the Goiano Federal Institute - Campus Morrinhos. The objective of this study was to evaluate the effect of 0%, 0.5%, 1.0%, 1.5% and 2.0% lime levels on the silage quality of sweet corn residue. It was used to make the silos plastic buckets, equipped with a busen valve in the lid. The silos were sealed with adhesive tape, weighed and stored in a covered area at room temperature, after 77 days the total dry matter and effluent losses were evaluated. The loss of effluents resulted from the difference in weight of the bucket + sand before ensiling at the weight after the silo opening. A completely randomized design with 3 replicates and five lime levels was used. It was verified a significant effect (P> 0.05) of the lime levels on the dry matter content and on the dry matter recovery of the silage. As the level of lime increases, dry matter and dry matter recovery decrease. The average values of mineral matter showed a linear increase with the addition of lime level in the silage, but without alteration of the fermentation profile. The pH presented a linear increase with the addition of the lime level in the silage. The use of lime does not improve the quality of sweet corn residue silage.
