“…The DMI (kg day -1 ) and DMI (BW%) of feedlot steers fed corn silage from the feed out face of trench silos were not affected by the different types of sealing (P> 0.05). This differs from that reported by Neumann et al (2018), who compared double seal and conventional seal, and found that the double seal resulted in greater DMI (kg day -1 ) (10.04 kg day -1 against 9.28 kg day -1 ) and DMI (BW%) (2.30% against 2.21%), due to the better acceptance of silage by animals, as there was no selection or predilection for the concentrate fraction of the diet.…”

“…These authors verified ADG of 1.810 kg day -1 for animals that received silage covered with double seal and 1.565 kg day -1 for animals fed silage sealed with conventional film. Permeability to O2 of plastic film is a crucial factor in maintaining the anaerobic environment inside the silo, especially in portions of the silo with greater exposure to the external environment, like the sides and the ramp, directly impacting the final quality of the ensiled material and in the productive performance of animals (Bernardes et al, 2012;Neumann et al, 2018).…”

“…The greater availability of digestible fractions of NDF favors the efficiency of use of the forage offered, contributing to raise the ADG, which is only achieved when there is maintenance of the anaerobic environment inside the silo during fermentation (Neumann et al, 2018). Like ADG, FC was influenced by the type of sealing (P> 0.05).…”

“…The better use of the fiber portion of the silage has a positive correlation with responses in increasing milk and meat production (Barlow et al, 2012). The digestibility of corn silages is extremely important, as foods with better digestibility values allow greater intake of dry matter, better use of the food supplied, allowing productive increases and collaborating to dilute production costs (Ferraretto and Shaver, 2015;Neumann et al, 2017).…”

“…In general, sealing must be uniform throughout the silo, but there is greater difficulty in compacting and correctly sealing the lateral and feed out faces (ramp) of the trench silo, making them more prone to deterioration, due to greater exposure to the external environment and temperature fluctuations, making the environment conducive to the action of aerobic microorganisms that promote spoilage of ensiled forage (Kung Junior, 2005;Bernardes, 2016). Many nutritionists decide to discard these portions of the silo for considering them of poor quality, low animal response and high health risk to animals regarding the real situation of the rest of the silo.According to Neumann et al (2018), the type of material used to seal the silo can positively affect the preservation of silage, resulting in higher productive performance of the animals, stimulating the daily dry matter intake and allowing less participation of the concentrated fraction in the diets. Plastic films based on double-sided polyethylene (white on black) are still the most used material to cover trench silos in Brazil (Bernardes et al, 2015), films with thickness ranging from 80 to 120µm are the most common.…”

This study aimed to evaluate the productive performance, dry matter intake, apparent digestibility and ingestive behavior of feedlot calves fed corn silage from the feed out face of trench silos with different types of sealing. The animals were divided into three treatments with four repetitions: Conventional seal - double-sided polyethylene of 110µm thickness; Double-sided seal - double-sided polyethylene of 200µm thickness; and Double seal - composed of double face polyethylene with a thickness of 80µm superimposed on a polyamide translucent vacuum film with a thickness of 20µm. The use of double face sealing provided 12.63% increase in average daily gain and improved food conversion by 0.62 percentage points. The apparent digestibility of the diet with double-face sealing system silage was 4.30% higher than the diet with double-face sealing silage and 11.00% higher than the diet with conventional sealing silage. It is recommended to use the double face sealing with 200µm polyethylene and double face sealing with 80µm thick polyethylene on top of a 20µm thick polyamide translucent vacuum film.

Effect of different double-sided plastic films on chemical and fermentation characteristics of corn silage

et al. 2021

View full text Add to dashboard Cite

The objective of this study was to evaluate the efficiency of different double-sided plastic films on chemical and fermentation characteristics, dry matter digestibility, aerobic stability, physical and dry matter losses in corn silages stored in bunker silos. This was a completely randomized experimental design consisting of three treatments: DF110µm - double-sided polyethylene with 110 µm thickness; DF200µm - double-sided polyethylene with 200 µm thickness; and DFBO - oxygen-impermeable film consisted of double-sided polyethylene with 80 µm thickness overlaid with a translucent vacuum polyamide film with 20 µm thickness. The use of DF200µm film increased the ruminal dry matter digestibility by 4.58% and reduced the silage temperature by 3.1 °C, as well as the physical losses of the corn silage were reduced by 118.9 g kg-1 DM using DFBO and 95 g kg-1 DM with DF200µm; DFBO resulted in the highest aerobic stability (127 hours) of corn silage. The use of DF200µm and DFBO is recommended for preserving corn silage in bunker silos.

A qualidade da confecção da silagem envolve diversas etapas, a qual exige a utilização de matérias específicos que evitem ao máximo o contato do material ensilado com o ambiente externo, visto que a retirada do oxigênio e o isolamento do material ensilado são fatores diretamente relacionados com a integridade do processo. O trabalho de pesquisa foi realizado no Núcleo de produção animal (NUPRAN) da Universidade estadual do centro-oeste (UNICENTRO), em Guarapuava, PR, Brasil, objetivando avaliar o efeito de vedação em silos de silagem de milho sobre perdas e valor nutricional da forragem, assim como sobre o desempenho, consumo de matéria seca, digestibilidade aparente e comportamento ingestivo de novilhos terminados em confinamento. As dietas foram constituídas por 35% de silagem de milho e 65% de concentrado, na base seca. O período de confinamento foi de 112 dias, sendo 28 dias de adaptação e 84 dias avaliativos divididos em 3 períodos de 28 dias cada. Foram utilizados 36 novilhos ½ Angus Nelore, machos inteiros, com peso médio inicial de 401 kg e idade média de 12 meses. O delineamento experimental foi em blocos casualizados, constituído de três tratamentos com seis repetições, onde cada baia com dois animais representou uma unidade experimental: T1 - PEBD90 (Lona dupla face de 3 camadas de polietileno de baixa densidade, com espessura de 90 µm); T2 - PEBD200 (Lona dupla face de 3 camadas de polietileno de baixa densidade, com espessura de 200 µm); e T3 - PEBD/PEAD (Lona em cor prata com 1 camada de polietileno de baixa densidade com polietileno de alta densidade em laminação cruzada em “x” entre os polímeros, com espessura de 150 µm). O uso do PEBD200 na vedação de silos de silagem milho promoveu redução de perdas, maior estabilidade aeróbia e aumentou a digestibilidade ruminal da MS em relação aos demais tipos de polietileno. Novilhos terminados em confinamento, com a alimentação de silagem de milho de silos trincheiras vedados com PEBD200 apresentaram maior ganho de peso médio diário (1,509 kg dia-1), digestibilidade aparente da matéria seca (63,39 %) e melhor eficiência de transformação da MS ingerida em carcaça (10,79 DMI DCG-1) comparativamente às vedações PEBD/PEAD e PEBD90. A vedação com PEBD200 é o mais indicado na conservação de silagem de milho, devido sua capacidade de proporcionar maior estabilidade aeróbia da massa ensilada, reduzir perdas durante o armazenamento, aumentar degradação ruminal da MS e melhorar o desempenho de novilhos terminados em confinamento.
