“…These results provided an increase of 13.3% in feed efficiency of animals fed rehydrated corn in replacement of dry corn. Similar to the results found in this trial, Jacovaci et al (2021) observed that the replacement of dry corn with rehydrated corn also did not affect the ADG, but there was a reduction in the DMI of 14.1% and an improvement in feed efficiency of 18.3%.…”

“…In recent meta-analyses about the effect of ensiling on the feeding value of flint corn grain for feedlot beef cattle, Jacovaci et al (2021) found that the inclusion of ensiled corn in diets increased total tract digestibility of DM by 4.59% and starch by 3.33%, decreased DM intake by 14.1%, and increased feed efficiency by 18.3% but did not affect average daily gain (ADG). However, these benefits of grain ensiling are based on three major factors (Gomes et al, 2020): moisture content (Owens et al, 1997), particle size (Rémond et al, 2004), and length of storage time (Hoffman et al, 2011).…”

We investigated the effects of corn grain, finely or coarsely ground, rehydrated and ensiled to 35% moisture in substitution of dry corn grain on performance of beef cattle in the feedlot. Forty non-castrated young Angus crossbred bulls with average age of 13±1.4 months and average initial body weight (BW) of 374±14 kg. The experiment was conducted in blocks by weight, and bulls were randomly assigned into four groups of five animals each in a 2 × 2 factorial scheme. The factors evaluated were particle size (finely and coarsely ground) and two grain sources (dry ground corn and rehydrated corn grain silage). The treatments were diets containing dry corn grain, finely ground (DCF; 1.86 mm); dry corn grain, coarsely ground (DCC; 3.53 mm); rehydrated and ensiled corn grain, finely ground (RCF; 1.86 mm); and rehydrated and ensiled corn grain, coarsely ground (RCC; 3.53 mm). Initial BW, final BW, average daily gain (ADG), feed efficiency, and intake of dry matter (DMI), acid detergent fiber, and metabolizable energy were not affected by treatment. Ensiling corn grain decreased DMI by 10.3% (11.6 vs. 10.4 kg/d for dry and ensiled, respectively) and increased feed efficiency by 13.3% (0.13 vs. 0.15 kg/d for dry and ensiled, respectively), but there was no effect of particle size, grain source, and their interaction on ADG. Effects of particle size and grain source were observed for fecal starch and total tract starch digestion, with evidence that treatments containing rehydrated corn diets showed greater efficiency in the utilization of dietary starch. Animals fed RCF diets showed lower fecal starch losses of 37, 55, and 75% when compared with treatments RCC, DCF, and DCC, respectively. Our results suggested that ensiled rehydrated corn grain improves feed efficiency in substitution of dry corn grain. The finely and coarsely ground of rehydrated and ensiled corn grain increases the digestibility of starch for finishing cattle in feedlot.

“…The predominant cultivation of corn hybrids in Brazil, with a higher proportion of vitreous endosperm [9][10][11], is negatively related to starch digestibility [12][13][14], making ensiling an advantageous practice in terms of storage management and nutritive value [15][16][17]. In addition, ensiling reduces insect and rodent damage normally seen in dry grains and increases starch digestibility [18][19][20].…”

This review aimed to analyze the effects of additives in producing silage from rehydrated corn grains for ruminants. The control treatment studies used in this analysis involved corn grain rehydrated with water only. To be included in the review, the studies needed to follow standardized criteria, including the absence of additives in the control treatment and the silage evaluation of the in animals such as cattle, goats, and sheep. A total of fifteen publications between 2014 and 2023 were included in the final dataset. The PROC ANOVA of SAS was used to compare the results, which included a random effect of comparison within the study, performing a paired comparison. It was observed that additives did not influence the chemical composition, pH, organic acid, ethanol content, microbial population, fermentative losses, aerobic stability, and dry matter in vitro digestibility of rehydrated corn grain silage (p > 0.05). Using additives in corn silage is a promising practice that can significantly benefit silage fermentation. Moisture silage additives mitigate high mycotoxin levels, enhance aerobic stability, improve cell wall digestibility, and increase the efficiency of utilization of silage nitrogen by ruminants. Using fermentation-stimulating additives (Lactobacillus buchneri) can improve the quality of rehydrated corn grain silage. There are still a few studies and more research to elucidate the best additives and the ideal amount to be added to ground corn grain silage.

“…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). Furthermore, the technique of ensiling corn grain or another cereal makes it possible to purchase this ingredient at times with lower market costs, which is essential on farms and, especially, in the semi-arid region.…”

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.
