“…However, at concentrations below 0.10% DM, they did not compromise the nutritional quality of corn silage (McDonald et al, 1991). Bueno et al (2020), who evaluated corn silage stored for 180 days, found no effect on the levels of butyric acid, corroborating the findings of the current study. Ammonia-N and non-protein N (A fraction) concentrations increased linearly, whereas crude protein and soluble true protein (B1 and B2 fractions) decreased linearly with storage (Tables 1 and 2), because of the proteolysis, which causes hydrolysis of protein peptide bonds through the action of enzymes present in plant cells generating non-protein nitrogenous compounds such as ammonia, nitrates, nitrites, free amino acids, and peptides (McDonald et al, 1991).…”

“…As the period of time for which the silages were stored increased, the DM content of the maize silage decreased and the effluent increased (Table 1). This may be the result of having harvested the crop before it reached a dry matter content of less than 300 g/kg (Bueno et al, 2020). Harvesting the crop too soon may have resulted in lower production per area and more intense fermentation.…”

The experiment evaluated the effects on the chemical composition (fermentation, kinetic parameters, and protein and carbohydrate fractions) of corn silage after various storage durations (45, 90, 180, and 360 days). Experimental mini silos of the corn plants were made and opened after various storage periods. The experimental design was completely randomized with four treatments and four replications per treatment. Variables such as pH, lactic acid and acetic acid showed a quadratic effect, whereas effluent and gas losses increased linearly with prolonged storage. Proteolysis was observed with an increase in storage, resulting in a rise in ammonia-N, soluble N, and non-protein N concentration and reduction in true protein. The soluble carbohydrate fractions were reduced, and digestible and indigestible fibre were increased. For the kinetic degradation parameters of the silages obtained through in vitro gas methodology, the highest fermentation rate occurred in the first 12 hours of incubation, and the highest volume of gas produced within 96 hours was obtained for silages with shorter storage (45 days). The increase in storage resulted in greater losses and lower ruminal degradability in vitro, causing a decrease in protein quality and nutritional value.

“…When processed through a conventional kernel processor (2 mm roll gap), Ferraretto et al [36] reported numerically greater processing scores in bm3 gene mutation and dual-purpose maize silage hybrids harvested at a late maturity compared to the same hybrids harvested at early maturity. Bueno et al [44] observed greater kernel processing scores in unprocessed WPMS harvested at 30% DM compared to 40% DM.…”

“…At 240 d of storage, differences between treatment combinations were diminished, with isSD being greater in early maturity silage processed through a 1 mm roll gap compared to late maturity silage processed through a 3 mm roll gap. Ruminal starch digestibility is often found to be greater in early maturity compared to late maturity WPMS [36,39,44]. In a meta-analysis by Ferraretto and Shaver [5], a reduction in total-tract starch digestibility was observed for diets containing WPMS with >40% DM.…”

Effect of Forage Processor Roll Gap Width and Storage Length on Fermentation Profile, Nutrient Composition, Kernel Processing Score, and Starch Disappearance of Whole-Plant Maize Silage Harvested at Three Different Maturities

Our objective was to assess the effect of forage processor roll gap width and storage length on fermentation, nutrient composition, kernel processing score (KPS), and ruminal in situ starch disappearance (isSD) of whole-plant maize silage harvested at different maturities. Samples from a single maize silage hybrid at three harvest maturities (1/4, 1/2, and 3/4 kernel milk line (early, intermediate, and late, respectively)) processed with two roll gap widths (1 and 3 mm) were collected and stored in quadruplicate vacuum pouches for 0, 30, 120, or 240 d. Lactic acid concentrations were greater, and pH was reduced in early and intermediate maturity silage compared to late maturity silage. Ruminal isSD was greatest for early maturity silage, intermediate for the intermediate maturity silage, and lowest for the late maturity silage, but differences in isSD due to maturity were diminished after prolonged storage. Kernel processing score was greatest in late maturity silage processed through a 1 mm roll gap and lowest in late maturity silage processed through the 3 mm roll gap. For early and intermediate maturity silages, no differences in KPS were observed between the two roll gap widths. Minimal effects of maturity and roll gap width on fatty acids (FA) and amino acids (AA) were observed. Concentrations of total AA decreased as storage length progressed. Results support the premise that the silo is a dynamic system that undergoes numerous chemical changes throughout the storage period.

“…O grau de estabilização é obtido com maior rapidez nos silos experimentais que nos comerciais, já que as condições para que ocorra o processo de fermentação anaeróbica se dá em menor tempo alterando os resultados. No Brasil, foram realizados poucos experimentos (PEDROSO et al, 2014;BUENO et al, 2020;MARTIN et al, 2012;TAVARES et al, 2009;TAVARES et al, 2019;OLIVEIRA et al, 2011;BUSO et al, 2018;CRUZ et al, 2019;NEUMANN et al, 2007;OLIVEIRA et al, 2013;MOMBACH et al, 2019) buscando estudar os microssilos experimentais utilizados para avaliação da silagem que se aproxime das condições de campo.…”

Objetivou-se, com o presente estudo, testar diferentes tipos, formas e volumes de silos experimentais na produção de silagem de milho e sorgo, para as principais características bromatológicas, matéria seca e concentração de nutrientes no tecido ensilado. O experimento foi conduzido na área experimental da Universidade Tecnológica Federal do Paraná, no Campus Dois Vizinhos no período entre dezembro de 2008 a junho de 2009. Os silos experimentais testados em ambas as culturas foram: baldes plásticos rígidos, com capacidade para 3 L e 15 L; canos de PVC de diferentes comprimentos e diâmetros, contendo ou não uma base com areia para armazenamento de efluentes; sacolas de plástico flexível com capacidade para 5 kg e 10 kg; e garrafas PET, com capacidade para 2 L. As características avaliadas foram: matéria seca, proteína bruta, fibra em detergente neutro, fibra em detergente ácida, extrato etéreo, matéria mineral, energia líquida de lactação, nutrientes digestíveis totais, teores de nitrogênio, fósforo, potássio, cálcio e magnésio no tecido vegetal. Também foram estimados os valores de ingestão de matéria seca, energia líquida de lactação e nutrientes digestíveis totais. Como resultados, verificou-se que o tipo de microssilo experimental não interfere nas características bromatológicas e teores de nutrientes, apenas o teor de matéria seca foi diferente entre os microssilos, para as culturas do milho e sorgo.
