“…These results are in agreement with those found by Santos et al (2014) who observed that the inclusion of glycerin was effective in reducing the NDF content and increase the DM content of sugar cane silages, proving to be a plausible strategy to compensate for the energy loss in the sugarcane ensiling. This change in the sugarcane chemical composition can mean an increase in quality, since, according to Van Soest (1994), the values of the cell wall constituents above 55-60% in DM negatively correlate with the DM intake and digestibility.…”

“…A longer exposure to air for silage with 10, 15 and 20% of glycerin was needed to register increases in EMT and pH elevation in the 120 hours of observation. Santos et al (2014) found that the sugar cane silage with 9% of glycerin reduced the production of lactic acid and tended to decrease the concentration of ethanol and glycerin dosage did not affect aerobic stability, different result found in this study.…”

“…In the experiment of Santos et al (2014) the differences in pH values between silages with and without glycerin occurred only after 120 hours of exposure to air when it was observed that the silage without the addition of glycerin, showed higher pH. Jobim and Gonçalves (2003) alerted to the deleterious effects of oxygenation of the ensiled mass, since the oxygen promotes the action of spoilage microorganisms and a reduction of soluble sugars and organic acids, resulting in increased pH and decreased digestibility and energy content.…”

“…The research of the use of biodiesel from glycerin as a component in animal feed has advanced and due to the high production of biodiesel and glycerin surplus, byproduct of high energy content, its addition in sugar cane silages could offset energetic losses caused by the ensiling process, facilitating the treatment of animals (SANTOS et al, 2014). The same authors found that the addition of 10% of glycerin reduced the population of clostridia in silage This study aimed to evaluate the effects of adding five levels (0, 5, 10, 15 and 20%) of semipurified glycerin to sugar cane silages and also evaluate the chemical composition, ruminal degradability, in vitro digestibility and aerobic stability of silages.…”

The experiment was performed with the objective of studying the ensiled sugarcane silage with 0, 5, 10, 15 and 20% of glycerin in experimental PVC silos. The aerobic stability was assessed by measuring the pH and the temperature of the silage at 0, 24, 48, 72, 96 and 120h. The chemical composition, the levels of non-fiber carbohydrates (NFC) and the total digestible nutrients (TDN) were evaluated. The in vitro digestibility of dry matter (IVDDM) and the in vitro digestibility of the cell wall (IVDCW) in the silages were evaluated. In three fistulated cattle the in situ degradability of dry matter (DM) and the disappearance percentage of the neutral detergent fiber (NDF) in samples incubated at 0, 2, 6, 12, 24, 48, 72 and 96h were analyzed. The experimental design was completely randomized and the statistical analyzes were done using Bayesian inference. Increases were observed in DM, TDN, mineral matter, NFC and reductions in NDF, acid detergent fiber, crude protein and ether extract as the inclusion of glycerin was higher. IVDDM increased (P <0.05) in silage with 15 and 20% of glycerin in relation to those with 0, 5 and 10%. The IVDCW at levels of 10, 15 and 20% of glycerin was higher (P <0.05) compared to the other treatments. Increases were observed in the soluble portion (a), a reduction in the insoluble fraction (b), and an increase in the degradability fraction constant (c) of the silages with 5, 10, 15 and 20% of glycerin (P <0.05) compared to the control. Glycerin improved aerobic stability while maintaining a low pH and temperature during the observation period at levels of 15 and 20% of glycerin against the silage with 0, 5 and 10%. These results indicate glycerin as a promising additive for sugarcane silage, being able to enhance energy density and improve the aerobic stability of the ensiled matter when its inclusion is from 10 to 20%.

Avaliou-se a estabilidade aeróbia medindo-se o pH e a temperatura da massa ensilada em 0, 24, 48, 72, 96 e 120h. Avaliaram-se a composição química, os teores de carboidratos não fibrosos (CNF) e nutrientes digestíveis totais (NDT). Avaliaram-se a digestibilidade in vitro da matéria seca (DIVMS) e da parede celular (DIVPC) das silagens. Em três bovinos fistulados avaliou-se a degradabilidade in situ da matéria seca (MS) e a porcentagem de desaparecimento da fibra em detergente neutro (FDN) em amostras incubadas em 0, 2, 6, 12, 24, 48, 72 e 96h. O delineamento experimental foi inteiramente casualisado e as análises estatísticas realizadas por meio de Inferência Bayesiana. Observaram-se aumentos na MS, NDT, matéria mineral, CNF e a redução de FDN, fibra em detergente ácido, proteína bruta e extrato etéreo à medida que a inclusão da glicerina foi maior. Houve aumento na DIVMS nas silagens com 15 e 20% de glicerina em relação à...

“…However, Li and Nishino () reported that P. kudriavzevii was detectable regardless of the actual state of deterioration in a L. buchneri ‐inoculated silage, suggesting that this species does not directly participate in aerobic deterioration. Candida humilis has been detected in several silages such as sugarcane and corn (Santos et al ; Santos et al ), while limited information about this yeast during aerobic exposure. Here, given that SE and SELB had a lower relative abundance of C. humilis than the other treatments, inhibition of C. humilis could be an effective strategy for improving the aerobic stability of ensiled TMR.…”

Aim To compare the effects of steam explosion and Lactobacillus buchneri inoculation on fungal community in ensiled total mixed ration (TMR) during aerobic exposure. Methods and Results The TMRs were prepared using wheat straw with or without steam explosion, sweet potato residue, lucerne hay, maize meal and soybean meal, and ensiled with or without L. buchneri inoculation. Fungal communities were detected by high‐throughput sequencing. All ensiled TMRs were well ensiled and steam explosion has a major effect on improving aerobic stability. The fungal species, such as Xeromyces bisporus and Cryptococcus victoriae, that dominated in the TMR decreased after ensiling, with a concomitant increase in Candida humilis, Pichia kudriavzevii, Aspergillus flavus and Phanerochaete chrysosporium. Most mould species decreased, with C. humilis and P. kudriavzevii dominating during aerobic exposure. Conclusion Steam explosion could improve the aerobic stability in ensiled TMR by inhibition of C. humilis. Significance and Impact of the Study High‐throughput sequencing used in this study provides insight into the fungal community in ensiled TMR during aerobic exposure, which could contribute towards elucidating the mechanism by which aerobic deterioration develops.
