“…Also, the lower concentration of lactic acid and higher pH were probably in part due to the clostridial fermentation that converts lactic acid to butyric acid (McDonald et al, 1991). Mombach et al (2019) also reported the benefits of increasing moisture content of RCG, with an improved fermentation pattern (low pH associated with less loss of gas and effluent) observed at approximately 38% of moisture. In our study, the concentration of butyric acid was highest in RCG with 30% of moisture compared with other treatments.…”

Our objective was to examine the effects of processing, moisture, and anaerobic storage length of reconstituted corn grain on the fermentation profile, geometric mean particle size and ruminal DM disappearance. Dry corn kernels were ground (hammer mill, 5-mm screen) or rolled, then rehydrated to 30, 35 or 40% moisture, and stored for 0, 14, 30, 60, 90, 120 or 180 d in laboratory silos. Rolled corn had an increased geometric mean particle size compared with ground corn (2.24 and 1.13 mm, respectively, at ensiling). However, there was a trend for an interaction between processing and moisture concentration to affect particle size, with geometric mean particle size increasing with increased moisture concentration, especially in ground corn. Longer storage periods also slightly increased geometric mean particle size. Processing, moisture, and storage length interacted to affect the fermentation pattern (two- or three-way interactions). Overall, pH decreased, whereas lactic acid, acetic acid, ethanol, and NH3-N increased with storage length. Reconstituted corn grain with 30% moisture had less lactic acid than corn with 35% and 40% moisture, indicating that fermentation might have been curtailed, and also due to the clostridial fermentation that converts lactic acid to butyric acid. Ensiling reconstituted ground corn with 30% of moisture led to greater concentrations of ethanol and butyric acid, resulting in greater dry matter loss than grain rehydrated to 35 or 40% of moisture. Ammonia-N and in situ ruminal dry matter (DM) disappearance were highest for reconstituted ground corn with 35 or 40% of moisture, mainly after 60 d of storage. Therefore, longer storage periods and greater moisture contents did not offset negative effect of greater particle size on the in situ ruminal DM disappearance of rolled reconstituted corn grain. Nonetheless, reconstituted corn grain should be ensiled with more than 30% moisture and stored for at least two months to improve the ruminal DM disappearance and reduce the formation of ethanol and butyric acid.

“…Corn (Zea mays L.) is one of the main ingredients used in ruminant diets to increase energy levels and animal performance (Bernardes & Rêgo, 2014;Mombach, Pereira, Pina, Bolson, & Pedreira, 2019;Daniel, Bernardes, Jobim, Schmidt, & Nussio, 2019). This is related to the chemical composition that contains 879.6 g kg -1 dry matter, 205.1 g kg -1 water-soluble carbohydrates and 714.5 g kg -1 starch (Valadares et al, 2016).…”

“…Thus, farms do not have adequate structures for storing corn and other cereals for use in animal feed throughout the year. The consequence of this lack of structure for storing grains is the damage caused by rodents, insects and fungi (Mombach et al, 2019). rehydrated (reconstituted) Thus, corn grain silage has been used to circumvent these losses (C. M. Silva et al, 2016), and to improve the starch digestibility of corn (Ferraretto, Silva, Fernandes, Kim, & Sultana, 2018) and nutrient utilization by ruminants (Castro et al, 2019;Jacovaci, Salvo, Jobim, & Daniel, 2021).…”

This study aimed to evaluate the effects of rehydration with water or acid whey, as well as the effects of bacterial-enzymatic inoculant on fermentation losses, aerobic stability, and chemical composition and in vitro digestibility of corn grain silages. The treatments consisted of corn kernels (Zea mays) ground through a 3-mm sieve and rehydrated with chlorine-free water or unsalted whey (NaCl) combined or not with bacterial-enzymatic inoculant. This was a 2 x 2 factorial completely randomized design with sources of rehydration (water or whey) and absence and presence of bacterial-enzymatic inoculant with eight replications. Water and acid whey were added to ground corn with 12% moisture in order to increase it to 35%. Rehydrated corn was ensiled in Polyvinyl chloride (PVC) minisilos and stored for 60 d. The bacterial-enzymatic inoculant used was composed of Lactobacillus curvatus, L. acidophilus, L. plantarum, L. buchneri, L. lactis, Pediococcus acidilactici, Propionibacterium acidipropionici and Enterococcus faecium, in concentrations of 1010 CFU g-1 and 5% cellulose-based enzyme complex. The aerobic exposure of silages was evaluated for 120 hours. There was interaction (P = 0.02) between the sources of rehydration and the use or not of the inoculant on the values of silage temperature during aerobic exposure. There was a difference for dry matter (DM) losses (P=0.38) between rehydrated corn silages with and without inoculant. DM losses were 37.51% higher in silage without inoculant compared to silage with inoculant (3.84% DM). There was no difference between the sources of rehydration on DM losses (P = 0.39), with a mean value of 4.99%. Corn rehydration using acid whey (P < 0.01) increased 2.19% and 31.36% DM and ash content compared to water, an average of 66.14% and 1.28%, respectively. There was no interaction (P = 0.30) between the sources of rehydration and the use of inoculants on the in vitro digestibility of DM (mean of 79.26%). The use of the bacterial-enzymatic inoculant improved the fermentation characteristics, aerobic stability and nutritional value of corn grain silage rehydrated with water or whey.

“…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.
