“…Castro et al (2006) evaluated the microbiological profile of silages of Tifton 85 bermudagrass with different dry matter concentrations and application of additives and observed sporadic colonies of Aspergillus sp, Penicillium sp in the initial sampling and absence in the other storage periods (32 and 180 days). Schocken-Iturrino et al (2005) evaluated the presence of fungi in Tifton 85 bermudagrass silages with wilting and citrus pulp and observed low aerobic stability and an increase in occurrence of Penicillium, Fusarium and Phitomyces as they were more exposed to air.…”

“…These pH responses did not differ from the initial pH of these treatments (Table 4). According to Cherney & Cherney (2003), pH still remains as a good indicator of fermentation quality in silages with low DM content and is not viable for silages with high DM content. The increase in contents of dry matter is required in silage conservation, since the decrease in water activity (Wa) can have an additional effect on the pH decrease (Lindgren, 1999).…”

“…Thereafter, pH was determined by a potentiometer in the aqueous extract formed by a fraction of 25 g of sample mixed to 450 mL deionized water, according to the methodology described by Cherney & Cherney (2003). Silage temperature was recorded with a digital skewer thermometer.…”

“…Silage and air temperatures as well as pH were measured. The pH was determined with a potentiometer, according to the methodology described by Cherney & Cherney (2003) and the silage temperature with a digital skewer thermometer. The increase of 1 o C above room temperature was considered a breach of aerobic stability (Driehuis et al, 2001).…”

-The objective of this study was to evaluate the microbiological profile and aerobic stability of silage with Tifton 85 bermudagrass and different additives and wilting. The studied treatments were: pre-drying in the sun for two hours before ensiling; use of bacterial-enzymatic inoculant; addition of soybean peel; addition of corn grits and use of salt in the surface layer of the silo. The experimental design was completely randomized with six treatments and four replications. Plants of Tifton 85 bermudagrass with 38 days were ensiled in experimental silos with Bunsen valves, with compacting density of 236 kg silage per m 3 for Tifton 85 bermudagrass, which was pre-dried in the sun; the average silage was 294 kg m -3 for the other treatments. The ratios between soybean hulls and corn grits, added to the silage, were calculated based on the initial DM content from Tifton 85 bermudagrass in order to obtain 320 g/kg DM of the material to be ensiled. There was an increase of lactic bacteria and Clostridium as well as an absence of enterobacteria after the silo opening. Fungi developed only in Tifton 85 bermudagrass and its treatments before the ensilage and yeasts developed in silages of Tifton 85 bermudagrass when they received soybean hulls or corn grits after silo opening. There was no breach regarding aerobic stability of silages during the studied period. The pH reached the highest values within 48 hours after opening the silos, but there were variations during this period.

“…A conservação dos alimentos em forma de silagem está sujeito a grandes variações, uma vez que a conservação depende da fermentação natural dos açúcares a ácidos, sob condições anaeróbicas, pelas bactérias ácido láticas, produzindo como produto final, principalmente o ácido lático e o ácido acético (SANTOS et al, 2001), sendo as alterações ocorridas durante os primeiros dias após a ensilagem, críticas para o sucesso da fermentação (CASTRO et al, 2006). (2001), os três fatores mais importantes para que se tenha uma boa silagem são a rápida remoção do ar, rápida produção de ácido lático que resulta em declínio do pH e a continuação da exclusão do ar da massa ensilada durante o período de armazenagem e fornecimento.…”

ResumoForam preparados minisilos experimentais, em delineamento experimental inteiramente casualizado, distribuídos em arranjo fatorial 2 x 5, sendo, 2 tipos de silagem (bagaço de laranja e milho) e 5 tratamentos (sem fonte protéica; com uréia; farelo de soja; farelo de algodão e farelo de girassol). Os aditivos protéicos foram adicionados para que cada silagem obtivesse um teor protéico ao redor de 10%. Os silos foram abertos 90 dias após o preparo das silagens. Foram determinados pH, ácido lático (AL), capacidade tampão (CATP), matéria seca (MS), proteína bruta (PB), nitrogênio amoniacal (NNH 3 ), extrato etéreo (EE), fibra em detergente neutro (FDN), cálcio (Ca), carboidratos totais (CT), carboidratos não fibrosos (CNF) e digestibilidade in vitro (DIV). Os aditivos protéicos aumentaram os teores de MS das silagens. O pH das silagens variou de 3,41 a 3,95, sendo a produção de ácido lático e a digestibilidade in vitro maior para a silagem de bagaço de laranja quando comparada à silagem de milho. Conclui-se que a silagem de bagaço de laranja pode ser adequadamente preservada na forma de silagem com aditivos protéicos. Palavras-chave: Ácido lático, capacidade tampão, farelo de algodão, farelo de girassol, farelo de soja, uréia AbstractExperimental mini-silos were prepared, in a completely randomized design distributed in a 2 x 5 factorial arrangement, with two silages (orange peel and corn) and five treatments (without protein source; with urea; soybean meal; cotton seed meal and sunflower meal). The protein additives were added to each silage to achieve about 10% protein. The silos were opened 90 days after the make silages. The following determinations were accomplished: pH, lactic acid (LA), buffering capacity (BC), dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), calcium (Ca), total carbohydrates (TC), non fibrous carbohydrates (NFC) and in vitro digestibility (IVD). The protein additives increased the DM averages of the silages. The pH of silages varied from 3.41 to 3.95, being the lactic acid and in vitro digestibility higher to the orange peel silage when compared to the corn silage. It can be concluded that the orange peel silage to be preserved in silage form with protein source.
