CARACTERÍSTICAS DA SILAGEM DE CANA-DE-AÇÚCAR COM ADIÇÃO DE ORA-PRO-NÓBIS

Abstract

Sugarcane is a tropical forage that stands out for its high productivity and for being supplied in natura form or silage, but it has disadvantage low protein content. The objective of this work was to analyze the quality of sugarcane silage for animal consumption after the inclusion of ora-pro-nóbis, a species with high protein content. The experiment was

conducted in a DIC design with four treatments (inclusion of 0, 10, 20 and 30% of ora-pro- nóbis) and three replicates. The sugarcane was harvested, ground and bagged, totaling 200 kg

of final weight. The same process was performed for the ora-pro-nóbis plant. At the time of

ensiling, inoculant was added to the ground sugar cane and, subsequently, the addition of ora- pro-nóbis was added in proportions of 0, 10, 20 and 30%. The ensiling process was done in 18

L buckets forming mini-silos. The quality of the silage was determined by: total dry matter, crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF), pH, acidity, effluent and gas production, loss and recovery of dry matter and mineral matter. After the analysis of the values found for the different samples, it was observed that the sugarcane sample with 30% of ora-pro-nobis presented satisfactory values in relation to the other samples, resulting in a silage with better value for animal consumption.
