“…The fermentation acids usually decreased as substrate by some aerobic microorganisms in response to aerobic exposure ( Cantoia Júnior et al, 2020 ; Guan et al, 2020 ). Indeed, in the present study, the concentration of lactic and acetic acids sharply decreased in CK, LP, CA, and LPPF groups as the prolonged of aerobic exposure.…”

“…Forage oat ( Avena sativa L.) is an important ruminant feed worldwide because of its good nutritive value and highly digestible fiber ( Gomes et al, 2019 ; Jia et al, 2021 ), and ensiling has been considered to be one of the most efficient ways to conserve forage oat. However, a high level of water-soluble carbohydrate might result in higher fermentation losses and susceptible to aerobic spoilage ( Cantoia Júnior et al, 2020 ). In particular, when silage is exposed to air, some species of yeast that survive in the ensiling process cause large nutrient losses ( Zhao et al, 2018 ), and often compromise the feeding value and hygienic quality of the silage ( Pahlow et al, 2003 ).…”

The aim of this study was to investigate the influence of Perilla frutescens, alone or in combination with Lactobacillus plantarum a214 or citric acid, on forage oat silage quality, bacterial and fungal microbiological profile during ensiling and aerobic exposure. With the exception of Perilla frutescens, all additives could improve silage quality of forage oat based on lower ammonia-nitrogen content and higher residual of water soluble carbohydrates during anaerobic fermentation compared to control silage, especially in Perilla frutescens combined with citric acid (CAPF). Lactobacillus was the dominant bacteria in all silages, while CAPF group increased the relative abundance of Lactobacillus lindneri and Lactobacillus brevis compared to control silage. The application of Perilla frutescens suppressed the relative abundance of yeasts such as Pichia fermentans and Wickerhamomyces anomalus in response to aerobic exposure, especially in CAPF treatment, leading to high acetic acids and lower dry matter loss, as well as good aerobic stability. Therefore, Perilla frutescens, alone or in combination with citric acid, has potential to improve aerobic stability of forage oat silage by shifting bacterial and fungal community composition, and can be used as new additive to prepare high-quality silage for animal production.

“…Furthermore, Foskolos et al [9] evaluated the use of essential oils levels of tymol, eugenol, and cinnamaldehyde in ryegrass silage, which were able to act as deamaination inhibitors and prevent proteolysis. Meanwhile, the increase in WSC content during storage due to the use of essential oils that have antimicrobial activity can prevent LAB from metabolizing WSC into organic acids [10]. The fiber content in this study was found to decrease in the parameters of NDF, ADF, ADL, and crude ash.…”

“…This is because using essential oils can stop the development of a number of harmful microorganisms, such as enterobacteria and clostridia [13], which is a producers of acetic acid [14] and butyric acid [6]. The use of lemongrass oil as a silage additive reduced the concentration of acetic acid to 2 mL/kg and reduced the content of butyric acid [10]. The decrease in the content of acetic and butyric acid also proves that essential oils are able to prevent the growth of clostridia, which can lead to a decrease in silage quality by converting sugar and organic acids into butyrate [6].…”

Essential oils are plant secondary metabolites that have potential as antimicrobial agents. The use of essential oils as silage additives is expected to maintain feed quality and prevent the growth of spoilage microbes during ensiling. This meta-analysis study aimed to determine the effect of levels of essential oils as silage additives on chemical composition and fermentation quality during ensiling. A total of 11 journal articles consisting of 17 studies and 73 data points were tabulated with related parameters about the chemical composition, fermentation quality, and microbial analysis. The results of the analysis indicate that increasing the levels of essential oils linearly increase (p<0.01) certain chemical compositions, such as crude protein, ether extract, and water-soluble carbohydrate, and simultaneously decrease (p<0.05) the contents of NDF, ADF, ADL, and crude ash. Fermentation products such as lactic acid, acetic acid, and propionic acid decreased (p<0.05) due to the additions of essential oils. Meanwhile, on the microbial parameters, it was found that the use of essential oils was able to reduce the mold population on silage (p<0.01). In conclusion, the addition of essential oils as silage additives maintained nutrient quality, decreased fiber content, and inhibited fungal growth.

“…However, the exclusive silage of sugarcane presents certain obstacles, such as low levels of dry matter (DM), crude protein (CP), and mineral matter (MM) (Cantoia Júnior et al, 2020). These factors can negatively affect the fermentation of the ensiled material due to the high humidity of the cane and nutritional quality of silages, which cannot be improved without the use of additives when ensiled.…”

We evaluated the contents of dry matter (DM), crude protein (CP), mineral matter (MM), soluble carbohydrates (CHOS), ammonia nitrogen (N-NH3), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in sugarcane silages to which different levels of inclusion (LI) of crambe bran (CB) were added in proportions of 0, 3, 10, 17 and 20% at different storage times (ST). Laboratory silos were used, predetermined ST being 0, 3, 7, 12, 24, 36, 41, and 60 days after silage. For statistical analysis, the response surface methodology was used, in which LI and ST served as independent factors and response variables as dependent factors. The levels of DM and CP increased linearly with NI; however, it did not show any significant response regarding ST. The CHOS contents were reduced linearly with NI and displayed a quadratic response with ST. The interaction between NI and ST for the levels of N-NH3 was significant, as the levels reduced with the NI and ST. The levels of NDF and ADF reduced linearly with NI and displayed a quadratic response with ST. The CB showed high efficacy to improve fermentation of ensiled cane, with the addition and conservation of nutrients in all NI evaluated and over the storage time. In addition to the residues generated with the production of biodiesel in a sustainable way, CB is a viable alternative to the sugarcane silage.
