“…The feed out face of trench silos is the portion of the silo with the most challenging environment for silage preservation, due to the difficulty of compacting and sealing the site, so it is suggested that there is a greater influence of the type of sealing used, impacting on the quality of the fermentation process and consequently in the ruminal degradability of the material. Neumann et al (2017) evaluated the digestibility of corn silage dry matter under different types of sealing in trench silos, and reported no statistical difference between conventional and double sealing systems, differently from that found in this research, where the silage from the conventional sealing presented the lowest ruminal digestibility in relation to the types of sealing.…”

“…In the same way, Junga and Trávnicek (2015) argued that the increase in temperature of the ensiled mass originates from the degradation of substrates, mainly by fungi and yeasts, which act in the presence of oxygen resulting in the elevation of the average pH values and lower nutritional value of the food due to aerobic deterioration. Neumann et al (2017), in a similar study, evaluated double sealing and conventional sealing, and reported average temperatures higher than those obtained in the present study (30.18 °C and 31.48 °C, respectively), and attributed the increase in silage temperature in the silo feed out face with the activity of aerobic spoilage microorganisms.…”

“…In general, high humidity silages have higher concentrations of NH 3 than dryer silages because of the more intense general fermentation in the former, and when the levels are higher than normal they are usually the result of the proteolytic activity of the clostrids (Kung et al, 2018). Neumann et al (2017) evaluated the digestible portion of the NDF fraction from corn silage subjected to different types of sealing, and reported that the digestibility of the double sealing system was 25.54% higher than the conventional system. Bernardes et al (2012) also found a 6% increase in NDF digestibility in double sealing compared to conventional sealing.…”

The objective of this study was to evaluate the efficiency of different types of sealing on the physical losses of dry matter, chemical and fermentation characteristics and in situ digestibility of the dry matter of corn silage stored in the feed out face (ramp) of trench silos. The experimental design used randomized blocks, composed of three treatments, namely: T1 - corn silage preserved with double-sided polyethylene of 110 μm thickness (conventional seal); T2 - corn silage preserved with double-sided polyethylene of 200 μm thickness (double-sided); and T3 - corn silage preserved with oxygen-impermeable film composed of double-sided polyethylene of 80 μm thickness on a translucent vacuum polyamide film of 20 μm thickness (double sealing), with four repetitions each. The use of double-sided polyethylene with 200 μm thickness (double-sided) and oxygen impermeable film composed of double-sided polyethylene and polyamide (double sealing), were effective in preserving the chemical composition, fermentation profile, raw protein composition and fiber quality, in addition, the use of these polymers resulted in greater ruminal digestibility of dry matter and reduced the pH, temperature, temperature gradient and physical losses of corn silage from the feed out face (ramp) of trench silos compared to the conventional sealing.

“…On the other hand, in Principal Component 2, the greatest influence on quality was the use of double-sided plastic film, which is related to silage storage. Double sealing did not affect the silage nutritional composition, but increased dry matter recovery (88.79% vs. 85.64%) and in vitro neutral detergent fiber digestibility (33.04% vs. 24.6%), when compared to the conventional version (NEUMANN et al, 2017).

Corn ensiling is a feed preservation practice used for ruminant production. During the process of making and opening the silos, the quality of the silage may change due to the entrance of air, which can cause damage and decrease the voluntary intake of the animals. The objective of this work was to evaluate the chemical composition of corn silages during their use in commercial bunker silos, as well as to correlate this with qualitative and quantitative characteristics related to the silage making process. Technical data on silage making and samples were collected from 14 bunker silos, with five samples collected along each silo (at 10, 30, 50, 70 and 90% of their lengths); additionally, two sampling methodologies were compared (“W” vs. layer collections in silo panels: top, middle and bottom). The values for the pH and titratable acidity (TA) were significant (p < 0.05) in relation to the sampling method, where the pH of the top was higher (3.8±0.5) than that of the middle and the bottom layers (3.6±0.3 and 3.5±0.3); therefore, the TA was lower in the top of the silos. The dry matter, ashes, crude protein, neutral detergent fiber, acid detergent fiber, pH, TA, as well as the silo sampling method during the unloading of commercial bunker silos did not differ for any of the variables (p < 0.05). Also, the particle size did not differ during the unloading of the commercial bunker silos (p > 0.05). According to the collected technical data, 78.57% of the bunker silos were built directly on the ground, the harvesting equipment was mostly borrowed from municipalities or farmers’ associations (for 35.7 and 28.5% of the farms, respectively), and in only 64.2% of the farms, the harvester was sharpened before silage cutting. Good practices were applied during the corn silage process and throughout the use of the silos, homogeneous quality was detected in the western region of Santa Catarina. Either “W” or layer collections can be used to sample corn silage.

“…Dessa forma, a obtenção de condições específicas para uma correta fermentação depende da manutenção de um ambiente anaeróbico no silo de armazenamento (Silva et al, 2015). Muitos fatores colaboram para a obtenção da anaerobiose, e a vedação do silo é essencial para preservar a massa ensilada, impedindo a entrada de ar e água que podem deteriorar a silagem, provocando o seu descarte (Neumann et al, 2017).…”

Neste trabalho, foram analisadas as propriedades bromatológicas da silagem de milho, utilizando diferentes filmes de vedação. Foram utilizados filmes nanocompósitos de polietileno de alta densidade (BPEAD)/argila organofílica (3 e 6%)/aditivo antimicrobiano comercial (0,5 e 1%), contendo 1% de piritionato de zinco disperso em acetato de vinila (EVA). Os filmes nanocompósitos foram preparados em extrusora monorosca utilizando a técnica de intercalação por fusão e, posteriormente, por extrusão plana para obtenção dos filmes com espessura de 60 a 200 µm. Também foi utilizada, para vias de comparação, uma lona dupla face comercial de 200 µm. Foram utilizados silos experimentais de PVC e, após 45 dias, a silagem foi avaliada quanto as perdas por deterioração aeróbica, gases e efluentes, densidade, avaliação sensorial, pH, estabilidade aeróbica, massa seca, matéria mineral e orgânica, proteína bruta, extrato etéreo e carboidratos. Todos os parâmetros bromatológicos analisados ficaram dentro das faixas requeridas para a produção de uma silagem de qualidade, não sendo possível observar variação significativa nas características químico-fermentativas em função da vedação utilizada. Os resultados dos filmes nanocompósitos produzidos demonstraram o mesmo desempenho quanto à conservação da silagem que a lona comercial.
