“…Silo bags are considered a very successful storage system for this product, since no significant quality losses are reported when the soybean is stored a 13.5% m.c. and the silo bag maintains a minimum airtightness to prevent the entrance of rainwater (Taher et al, 2014a(Taher et al, , 2014b.…”

“…Na maioria das propriedades rurais, nos últimos anos vem sendo difundido o uso do silo tipo Bag, que consiste em uma grande bolsa feita de polietileno (TAHER et al, 2019), também tem sido utilizado sacos de polietileno para conservação e armazenamento de silagem, pois facilita o manejo de fornecimento aos animais e transporte da silagem.…”

A elaboração e utilização de minissilo de polietileno poderia contribuir para as análises de silagens experimentais, por utilizar material já empregado para a produção e comercialização de silagem ensacada, o que permitiria condições de fermentação mais próximas àquelas observados no campo. Objetivou-se neste estudo, avaliar os perfis fermentativos das silagens de capim elefante em minissilos de tubo policrometo de vinila (PVC) ou de sacos de polietileno inoculados com fungos do trato digestório bovino. O experimento foi conduzido em delineamento inteiramente casualizado, em fatorial 2x2, comparando-se a adição (MIX) ou não (CONT) dos fungos celulolíticos para a fermentação do capim elefante acondicionado nesses dois tipos de minissilos, com sete repetições para cada tratamento. O uso do minissilo de saco de polietileno quando comparado com de tubo PVC não apresentou diferença significativas nos parâmetros bromatológicos, estabilidade aeróbica, pH na abertura, entretanto na contagem de estreptobastonetes houve diferença significativa para a contagem de populações microbianas na abertura. As médias dos valores de pH dos minissilos na abertura se mantiveram < 4,5, houve diferença entre o MIXSACO (4,4) e o controle saco (CONTSACO) (3,83) (p= 0,004). Os minissilos CONTSACO apresentaram menor tempo de estabilidade (1,57 dias) em comparação com os demais minissilos (p=0,002). A utilização do saco de polietileno não prejudicou o processo fermentativo da forragem, sendo assim uma alternativa viável para substituição do silo de tubo PVC para produção de silos laboratoriais.Palavras-chave: Pennisetum purpureum. Minissilo. Forragem Tropical. Microrganismos Ruminais. Conservação de Forragem AbstractThe development and use of polyethylene minisilo could contribute to the analysis of experimental silages, by using material already used for the production and commercialization of baged silage, which would allow fermentation conditions closer to those observed in the field. The objective of this study was to evaluate the fermentative profiles of elephant grass silages in polyvinyl chloride tube (PVC) minisilos or polyethylene bags inoculated with fungi from the bovine digestive tract. The experiment was conducted in a completely randomized design, in a 2x2 factorial, comparing the addition (MIX) or not (CONT) of cellulolytic fungi for the fermentation of elephant grass packed in these two types of minisilos, with seven replications for each treatment. The use of the polyethylene bag minisilo when compared to PVC tube showed no significant difference in bromatological parameters, aerobic stability, pH at opening, however in the count of streptobastonetes there was a significant difference for the counting of microbial populations at the opening. Themean of the pH values of the minisilos at the opening remained < 4.5, there was difference between MIXBAG (4.4) and bag control (CONTBAG) (3.83) (p= 0.004). CONTBAG minisilos showed shorter stability time (1.57 days) compared to other minisilos (p=0.002). The use of the polyethylene bag did not harm the forage fermentation process, thus being a viable alternative for replacing the PVC tube silo for the production of laboratory silos.

Damage to silo bags by mammals in agroecosystems: a contribution for mitigating human–wildlife conflicts

ContextDamage to harvest storage systems by mammals and associated postharvest losses generate human–wildlife conflicts. Silo bags have been widely adopted worldwide as a type of temporary harvest storage for agricultural crops. The basis of silo-bag technology is the hermetic condition of the plastic lining. Breaks in this silo-bag lining by mammals generate damage of stored content and are a serious concern for farmers, who generally take actions against wildlife with consequent impacts on the environment. AimsWe described the incidence and intensity of breaks in silo-bag linings by different mammal groups (armadillos, canids and rodents) in agroecosystems of central Argentina, and we analysed the influence of extrinsic and intrinsic factors on patterns of breakage of silo bags, and propose management options based on cultural methods tending to prevent damage and reduce human–wildlife conflicts. MethodsSampling was conducted during the austral summer and winter of 2018, at three sites in the Pampas of Argentina. At each site, we chose farms that were using at least one silo bag, described silo-bag characteristics, and recorded the number of breaks in silo bags generated by mammals. Key resultsWe sampled a total of 306 silo bags from 38 farms. Damage incidence by mammals comprised 49% of silo bags sampled. Statistical analyses (GLMMs) revealed that damage intensity generally increased with storage time. Seasonality played a key role, with breakage being higher during summer for armadillos, when they are most active, and in winter for rodents, when they are most abundant. Damage by armadillos exhibited geographic variation and also decreased significantly with increasing distance to the nearest plot edge in which the silo bag was placed. Damage by rodents was higher for bags containing grains rather than forage. ConclusionsDamage to silo bags by mammals was affected by both extrinsic (seasonal and geographical) and intrinsic (stored content, storage time and distance to nearest edge) factors; however, these effects varied according to the mammal group considered. ImplicationsRelocation of silo bags away from plot edges could significantly reduce damage by armadillos, the most harmful mammals to silo bags.
