“…The most significant change in fermentation pattern was observed in LAB heho silage, as reflected by very high acetic acid concentrations and the lowest content of lactic acid [7]. The low DM at ensiling may have caused intensive metabolic activity of L. buchneri, supporting recent data by Gomes et al [49], who determined higher acetic acid contents in direct-cut than in wilted whole-crop oat silage. Obviously, L. buchneri, which can anaerobically degrade lactic acid to acetic acid, and 1,2-propanediol [50] dominated the fermentation in our trial.…”

“…Additionally, storage length may affect 1,2-propanediol conversion, as described by Auerbach and Nadeau [54] using the same LAB heho product and the same chemical additive SNHEPS in grass-clover silage of 35% DM. More so, Gomes et al [49] showed an effect of DM at ensiling on L. diolivorans activity demonstrating limited osmotolerance of this species. Despite the same total concentration of the three compounds involved in its unique metabolic pathway in untreated and L. buchneri-inoculated silage, direct-cut oat silage had much higher concentrations of n-propanol and propionic acid and contained less 1,2-propanediol than detected in silage from wilted forage.…”

“…Schmidt et al (2012) observed GV production in corn silages lower than the untreated sugarcane silage from our trial (424 vs 7282 L t −1 DM); this was also the case with GHG emission (14.5 vs 311 g CO 2 eq t −1 fresh forage). Contrary to our data, Gomes et al (2019) reported higher GV (27640 vs 10880 L t −1 DM) as well as ethanol synthesis (5.60 vs 1.43 g kg −1 DM) in wilted oat silage treated with LB than in untreated silage. Those authors indirectly estimated GV, which may have led to much higher values than ours.…”

“…Carvalho et al 2008, reiteraram a influência do nitrogênio amoniacal nos teores dos ácidos orgânicos no interior do silo, devido a maior proliferação de microrganismos indesejáveis, além de sua ação na neutralizadora do ácido lático. Esse ácido é o principal responsável pelo rebaixamento do pH no interior do silo (GOMES et al, 2018).…”

“…Pelos resultados apresentados na Figura 1 C, o pH atingiu um ponto de mínimo que foi de 73,5 dias de fermentação com pH de 4,0, estando fora da faixa estabelecida nos tratamentos. Portanto, não houve tempo hábil de estabilização do pH, dessa forma, os resultados para o pH foram influenciados pelo nitrogênio amoniacal (Figura 1 D), tendo em vista que, o poder tampão foi linear e crescente em decorrência da resposta do nitrogênio amoniacal, que atingiu seu ponto de máximo fora a faixa estabelecida nos tratamentos, dificultando o abaixamento do pH, pois esse composto no interior do silo, pode neutralizar o ácido lático, devido a dissociação de H + , quando há muito nitrogênio livre ocorre a "captura" destes íons, formando NH 4+ que, dependendo da quantidade formada, promove um aumento de pH do meio (GOMES et al, 2018) Para o nitrogênio amoniacal houve resposta quadrática crescente com ponto de máximo aos 68,8 dias de fermentação (fora da faixa estabelecida) atingindo uma concentração de 5,5% de nitrogênio amoniacal. Essa resposta para o nitrogênio amoniacal pode ter sido influenciada pelo baixo teor de MS do material ensilado (Tabela 1), o que pode ter facilitado a proliferação de microrganismos indesejáveis.…”
