“…All silages had low pH values (≤3.86); however, the microbial inoculants modulated the fermentation, retaining SC and reducing the concentrations of ethanol, lactic acid, and most trace compounds. As previously reported (Daniel et al, 2013b), ethanol and lactic acid concentrations were positively correlated (r = 0.74; P<0.01), emphasizing that homolactic fermentation is undesirable in sugarcane silages.…”

“…Although the production of lactic acid dominates fermentation in traditional silages (e.g., corn, grass and alfalfa silages) (McDonald et al, 1991), in sugarcane silages, ethanol is the major fermentation end-product (Daniel et al, 2013b). All silages had low pH values (≤3.86); however, the microbial inoculants modulated the fermentation, retaining SC and reducing the concentrations of ethanol, lactic acid, and most trace compounds.…”

“…Therefore, ensiling sugarcane results in the conversion of most of the SC into fermentation end-products, which are characterized by high levels of volatile organic compounds, primarily ethanol (Kung and Stanley, 1982;Pedroso et al, 2005;Daniel et al, 2013b). Although the gross energy is almost completely recovered during alcoholic fermentation (McDonald et al, 1991), large amounts of DM and net energy are lost (Daniel and Nussio, 2011;Daniel et al, 2013a).…”

“…In the present study, L. buchneri increased the acetic acid content by 31.5% and decreased the ethanol concentration by 70.8%. Nevertheless, ethanol concentrations were much lower than those reported in the literature (Zopollatto et al, 2009;Daniel et al, 2013), probably because of partial volatilization during silage feedout.…”

-Lactobacillus buchneri 40788 and the fibrolytic enzymes β-glucanase and xylanase were applied to chopped sugarcane to study their effects on the nutritive value of silage. Sugarcane was mechanically harvested after 14 mo of growth and treated without (control) or with L. buchneri at a theoretical application rate of 5 × 10 4 cfu/g, 1 × 10 5 cfu/g, or 1 × 10 5 cfu/g plus enzymes. Forage was packed into farm-scale bag silos (40 t/silo) and stored for 92 d. Fifty-six bulls (32 Nellore and 24 Charolais × Nellore) were housed in 20 collective pens and fed diets comprising (dry matter [DM] basis) 458 g/kg sugarcane silage and 542 g/kg concentrates for an 84-d period. Treated silages had higher concentrations of acetic acid and lower concentrations of ethanol. Total mixed rations (TMR) containing inoculated silages exhibited significantly lower neutral detergent fiber (NDF) concentration and, consequently, higher in vitro DM digestibility (IVDMD). Thus, animals fed TMR containing treated silages spent less time chewing per day and per kilogram of DM intake (DMI), even at higher DMI levels. Nonetheless, the intake of NDF was similar across treatments (0.77 to 0.79 kg/100 kg BW) but markedly lower than the value reported for traditional forages. Average daily gain was significantly greater for animals fed TMR based on inoculated silages due to the higher DMI (14% on average) and the higher energy content of the diets, as indicated by the higher feed efficiency (12% on average). The dose of inoculants used and the addition of fibrolytic enzymes had no significant effects on silage parameters or animal performance. Therefore, inoculation of L. buchneri during sugarcane ensilage can alter the fermentation pattern by increasing acetic acid yield, reducing silage nutrient losses, and improving feed efficiency by bulls.

“…Ethanol is the main fermentation end-product in apple pomace silages (Alibes et al 1984). Ethanol contents of several silages have been reported to be 12 -15 g/kg DM for corn silages (McDonald et al 1991;Raun and Kristensen, 2010), 8 -14 g/kg DM for grass silages (Lawrence et al 2011), 10 -23 g/kg DMfor ensiled TMR silages (Cummins et al 2009), 54 g/kg DM for sugarcane silage (Daniel et al 2013) and 173 g/kg DM for APS (Alibes et al 1984). Therefore, most of the ruminants are adapted to some ethanol intake.…”

Two experiments were undertaken to investigate the feeding effect of alcoholic apple pomace silages (APSs) on performance traits, ruminal pH and blood variables in sheep. In experiment 1, four ewes were fed alfalfa hay cube and either APS (ethanol content was 33.4 g /kg DM) or concentrate (control) at a ratio of 30:70 of TDN requirement for maintenance and daily 100g gain in a 2×2 crossover design over two 35-day periods. Total body weight gain was higher in control treatment. No significant treatment effect was observed for TDN intake and ruminal pH. Plasma concentrations of ethanol, lactate and β-hydroxybutyrate (BHBA) were increased after feeding APS. Plasma insulin, glucose, glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) were not significantly differ between the treatments. The area upper or under curves (AUCs)of plasma ethanol and BHBA were greater and lactate was tended to greater in APS treatment. In experiment 2, low and high ethanol contained APSs (L-APS, 44.1g and H-APS, 66.9 g of ethanol/kg DM) were compared in the same design (Experiment 1). No significant treatment effect was observed for body weight gain and TDN intake. Prefeeding ruminal pH was lower in L-APS treatment. Insulin concentration was slightly higher in L-APS treatment. However, no significant treatment effect was detected for other variables. According to the consistent increase in plasma ethanol, lactate and BHBA, and the plasma AUCs response of ethanol, lactate and BHBA after feeding of alcoholic-fermented APSs, it would be concluded that APS ethanol consumption affect the post prandial blood metabolism as well as influenced the plasma lactate and BHBA concentrations in the blood.
