Abstract

The aim of this study was to measure the chemical composition, microbiological profile, fermentative characteristics and the aerobic stability of the olive bagasse silages in natura and added with corn bran, soybean and rice bran in different times of sampling. The was completely randomized design in arrangement of plots subdivided in 4x3 time, with five replications. In the plots were allocated the main treatments, and in the subplots the sampling times were allocated. The fermentative characteristics was studied by determination of the dry matter (DM) content, pH and ammoniacal nitrogen (NH3-N), the microbiological by determining the populations of filamentous fungi, Clostridia, lactic acid bacteria and enterobacteria. In the nutrient profile study, the contents of mineral matter (MM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, cellulose, hemicellulose, nitrogen bound to acid detergent fiber (NIDA), nitrogen bound to neutral detergent fiber (NIDN), carbohydrate and total digestible nutrient (TDN). At the ensilage moment, it also has been determined in vitro dry matter digestibility (IVDMD) and in vitro digestibility of organic matter (IVDOM). The use of corn and rice bran provided a better fermentative profile in the studied ensilage. The pH of the silages added corn and rice bran has presented in 4.00 and 4.06 after 112 storage days, consequently. The adding of soybean bran provided the greatest CP values and non-fibrous carbohydrates (NFC) after the fermentative period, been it 131.55 g kg-1 of DM for CP and 176.28 g kg-1 of DM for NFC. The treatments without bran adding and rice bran added have demonstrated IVDOM levels of 581.12 g ka-1 od DM and 604.51 g kg-1 of DM, consequently. The studied meals improve the nutritional profile of the studied silages and are potentially usable as additives in olive bagasse silages.
