“…dos Anjos et al (2018) exposed inoculated and re‐ensiled sorghum to air for 12 h and verified a reduction in ammonia and lactic acid and an increase in propionic acid. Santos et al (2021) analysed re‐ensiled sorghum after exposure to air for 8, 16, and 24 h and found a linear regression increase in butyric acid and N‐NH 3 .TN −1 . de Lima et al (2016) verified a linear regression increase for pH when studying re‐ensiled corn for 12, 24, and 48 h.…”

“…Santos et al (2021) studied intake, digestibility, methane emission, and energy losses in sheep, and observed that silage re‐ensiled after 24 h did not affect animal efficiency. Overall, data on intake, apparent digestibility, and feeding behaviour of animals treated with inoculated and re‐ensiled material remains incipient in the literature.…”

This study aimed to determine whether using inoculants and re‐ensiling in sorghum silages affect the intake and feeding behaviour, apparent digestibility, digestible energy, and nitrogen balance of sheep in maintenance. Half the sorghum was inoculated on the day of harvest, and the other half received the same inoculation volume but with water. Sorghum was ensiled in 100 experimental metal drum silos of 200 L covered with plastic: 50 silos with inoculants and 50 without them. After 56 days, 25 drums with inoculants and 25 without were exposed to air for 48 h. The other silos remained closed. The treatments were arranged in a 2 × 2 factorial scheme with inoculation and re‐ensiling. The sheep received the silages after 211 days of ensiling and 155 days of re‐ensiling to determine the intake, apparent digestibility, and feeding behaviour of animals. The experimental design was a simultaneous double 4 × 4 Latin square. The re‐ensiling process increased silage pH, N‐NH3.TN−1, butyric acid, and propionic acid. The inoculant increased propionic acid in ensiled and re‐ensiled silages. Lactic acid concentration presented a statistical interaction with the inoculated and ensiled silage, 58% higher than the other treatment averages. The ADFap digestibility showed a complex interaction, in which the control ensiled and the inoculated and re‐ensiled silages were about 35% lower than the inoculated ensiled silage. The Nbal:Nint ratio (g.g−1) in the inoculated and re‐ensiled silage had lower nitrogen retention than intake compared with the other treatments. These results indicate that exposing inoculated silages to air does not compromise their use in sheep feeding.

“…Some microbial inoculants have been used to reduce possible nutritional and dry matter (DM) losses due to re-ensiling. Studies on the effect of reensiling and microbial inoculant use are recent (Chen and Weinberg, 2014;Michel et al, 2017;Dos Anjos et al, 2018;Santos et al, 2021). More information is needed regarding the re-ensiling process and microbial inoculants use containing Lactobacillus plantarum and Propionibacterium acidipropionici on the maize silage quality.…”

Re-ensiling has increased worldwide due to the increase in marketing of silage between farms. However, litlle is known about the aerobic deterioration and microbial inoculants effect in this process. The aim of this study was to determine the re-ensiling and microbial inoculant use effects on the maize silage quality. Experimental treatments included maize silage exposed to air for zero or 18 h, with or without microbial inoculant use containing a mixture of Lactobacillus plantarum and Propionibacterium acidipropionici. The forage was ensiled in 20 plastic buckets (20 liters capacity) with five repetitions per treatment. The silos were opened after 116 days and the chemical composition, in vitro dry matter digestibility (IVDMD), fermentative parameters, microorganism counts, total dry matter (DM) losses and aerobic stability of silage were evaluated. Re-ensiling reduced the non-fibrous carbohydrates content by 14.8%, whereas it increased the neutral detergent fiber content by 6%. The IVDMD was reduced by 6.1% in re-ensiled silages. In addition, re-ensiling increased the losses due to gases, effluents, and total DM. Lower lactic acid content and higher acetic acid content in re-ensiled maize silages were also observed. However, IVDMD increased by 4.6% in inoculated silages. Re-ensiling reduced the nutritive value and IVDMD of maize silages and should be avoided in production systems. The microbial inoculant use was not effective in improving the re-ensiled silage quality, which does not justify its use in these conditions. Farms should avoid purchasing maize silage due to reduction in nutritional value in the re-ensiling process. However, in some cases where farms need to purchase silage for feeding planning, the time between silo opening and re-ensiling should be as short as possible to reduce nutrient loss. Furthermore, in this situation the inoculant use does not improve silage conservation, which makes its use unnecessary.

The objective of this work was to determine the effects of sealing delay for 12 hours and of the use of microbial inoculant with heterofermentative bacteria on whole-plant corn (Zea mays) silage. The experimental design was completely randomized in a 2×2 factorial arrangement (with or without inoculant × with or without sealing delay). Silage was evaluated for: chemical composition in vitro dry matter digestibility (IVDMD), fermentative parameters, losses, aerobic stability, and microbiological profile. The heating of the silage caused by respiration increased the contents of neutral detergent insoluble protein and of acid detergent insoluble protein by 77 and 27.3%, respectively. Soluble carbohydrate losses increased the contents of neutral detergent fiber corrected for ash and protein by 9.1% and of acid detergent fiber by 5.1%, but decreased the content of nonfibrous carbohydrates by 11.2%. IVDMD did not differ between treatments. Silages with delayed sealing and the inoculant showed higher pH and contents of acetic acid, propionic acid, and ammoniacal nitrogen, but a lower content of lactic acid. Delayed sealing reduces the nutritional value, increases the fibrous fractions, and decreases the soluble carbohydrates, whereas the use of inoculant does not improve the nutritional value and aerobic stability of the silages.
