“…Although GL increased 120 days after ensiling, the results observed in the current study are similar to those of corn grain silages rehydrated with water, as observed by Ávila et al . (2019), who found values of 6.3% for GL. However, these authors evaluated only one opening time (90 days after ensiling the material).…”

“…(2011) during the corn grain ensiling process, proteolysis occurs, which results in the degradation of the protein matrix that surrounds the starch granules, explaining the increase in rumen degradability. Therefore, the use of cactus pear as a corn grain moistening additive, intensifies the grain fermentative process when compared to the results found in the literature for water-rehydrated corn grain silage (Arcari et al ., 2016; Carvalho et al ., 2017; Da Silva et al ., 2018 a , 2018 b , 2019; Ávila et al ., 2019). In addition, the corn grain silage rehydrated with cactus pear presents increased degradability in the first 30 days of the fermentative process, which is important because it allows silos to be opened and the silage to be used earlier when compared to water-rehydrated corn silage.…”

The current study aimed to evaluate the effects of cactus pear as a moistening additive on fermentative and microbiological characteristics, aerobic stability (AS), chemical composition and in situ rumen degradability of corn grain silage at different opening times. A completely randomized experimental design was adopted in a 4 × 3 factorial scheme with four levels of dry matter (DM) (50; 60; 70 and 80% of DM) and three opening times (30; 60 and 120 days after ensiling), with four replications. There was an effect of interaction (P < 0.05) between the DM levels and opening times on silage yeast population, effluent losses, gas losses, dry matter recovery (DMR), AS of the silage and on lactic acid bacteria, mould and yeast populations after AS trial. The 60% DM level presented DMR values above 930 g/kg of DM. However, the lowest AS time (96.52 h) was observed in silages with 60% DM at 60 days after ensiling, although all silages have shown high AS. The DM in situ degradability of the ensiled mass increased after the ensiling process at all DM levels and opening times, with the 60% DM content showing the best result. When using cactus pear as a corn grain moistening additive, the 60% DM level is recommended when the opening time is up 120 days.

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.
