“…This effect was observed not only during ensiling but also during the aerobic stability test. This finding is in agreement with those reported by Chen et al (1994) or Aksu et al (2004). Moreover, when Lactobacillus plantarum was used for silage inoculation, a higher increase in the concentration of LA was found (Winters et al, 2000) compared to the results reported by us.…”

“…After 14 days of ensiling a significant decline of pH was detected in the inoculated silage and the effect of E. faecium EF9296 on the value of pH was prolonged until the end of experiment (including the aerobic stability test). The inoculation of silage with homofermentative or heterofermentative LAB revealed the lower value of pH (between 3 and 4) compared to the results of our study (Ranjit and Kung, 2000;Winters et al, 2000;Aksu et al, 2004). For example, in the silage inoculated with a mixture of LAB consisting of Pediococcus, Lactobacillus and Enterococcus spp., the pH value 3.76 was measured after 112 days of ensiling (Zahiroddini et al, 2004).…”

A new probiotic, bacteriocin-producing strain of Enterococcus faecium EF9296 (isolate of our laboratory) was used in grass ensiling as an inoculant. The antimicrobial effect as well as the nutritive quality of silage was evaluated along with the aerobic stability test. Grass was ensiled with EF9296 strain (109 colony-forming units per gram of fresh material) and the silage without EF9296 was also prepared. The silages were processed in 1-litre plastic bottles. The samples were collected at days 0–1 (start of experiment), 7, 14 and 105 of ensiling to check the microbial status and chemical parameters of silage. At the end of ensiling period (day 105) the silages were subjected to an aerobic stability test for 7 days. The EF9296 strain survived and colonized the silage in sufficient counts (109–1010 cfu/g). The total counts of enterococci and lactic acid bacteria were increased. In the silage inoculated with EF9296 strain, a reduction in E. coli, enterobacteriae, staphylococci and Bacillus-like bacteria was noted mainly at day 7 and 14 of ensiling. Moreover, the counts of Listeria and moulds were reduced during the aerobic stability test. The silage inoculation resulted in a more rapid drop of pH, higher level of lactic acid and in a decrease in the concentration of acetic and butyric acid. The effect of E. faecium EF9296 on the value of pH was prolonged until the end of the experiment (including the aerobic stability test, below 4.3). During the whole ensiling period an increase in DM content in the experimental silage was detected. The E. faecium EF9296 strain represents a promising silage additive to produce silage of good quality and/or to prevent silage contamination.

“…Neutral detergent fibre was reduced in fermented green (P=0.01) and oolong tea (P=0.05) residues compared to their unfermented residues. This result agrees with the findings of [20] and [21] who suggested that the reduction in NDF could be due to the stabilization characteristics of the microbial inoculant. Acid detergent fibre concentration was lower (P=0.006) for the fermented than unfermented coffee residue.…”

Abstract-The aim of this study was to increase the nutritive value of coffee, green and oolong tea residues and assess if the fermented residues have the potential to mitigate enteric methane emissions. A mixed microbial culture (20 g/kg) was added to each residue and the mixture incubated for 3 d at 35°C (anaerobically) and 2 weeks at 30°C (aerobically). Unfermented and fermented beverage residues were assayed for their saccharide and ethanol content. Four separate total mixed rations (TMR) were prepared using the three fermented beverage residues and hay (control). The fermented residues (2 g dry matter (DM)) were individually mixed with hay (3 g DM) and concentrate (5 g DM) and the in vitro rumen methane output was quantified during the 24 h incubation period using the continuous gas quantification system. The fermented residues of coffee, oolong tea and green tea had higher concentrations of cellotriose, cellobiose and xylobiose than the corresponding unfermented residues. Ethanol concentration was higher in the fermented coffee and green tea residues than in their respective unfermented residues. The methane output (L CH4/24 h) from the TMR containing fermented residues of coffee (0.118 L), oolong tea (0.127 L) and hay (control; 0.123 L) did not differ, but the methane output was lower for all compared to the TMR containing fermented green tea residue (0.141 L). The results suggest that fermented coffee, oolong tea and green tea residues are a potentially good source of protein and energy, and fermented residues of coffee caused a numerical decrease methane output.Index Terms-Beverage residues, in vitro, methane, mixed microbial culture.

“…Homofermentative and heterofermentative LAB inoculants are two types of inoculants commonly used in silage production. Homofermentative LAB such as Lactobacillus plantarum, generally increases lactic acid and decreases acetic acid, butyric acid and ammonia-nitrogen (NH 3 -N) levels, and the pH of the silage (Sheperd et al, 1995;Aksu et al, 2004). However, homofermentative LAB often increases aerobic deterioration of whole-crop cereal silages, probably because of insufficient VFAs to inhibit fungal growth (Weinberg et al, 1993;Filya et al, 2000;Kleinschmit & Kung, 2006b).…”

Effects of a dual-purpose bacterial inoculant on the fermentation characteristics of high-moisture maize silage and dairy cattle performance

________________________________________________________________________________ AbstractThe objective of this study was to investigate the effects of inoculating Lactisil Maize, a dual-purpose inoculant, on the fermentation characteristics and nutritive value of high-moisture maize silage and the performance of lactating cows receiving the silage in their diets. Whole-crop maize was harvested at 253 g dry matter (DM)/kg fresh crop. Maize silage was produced with or without Lactisil Maize and ensiled in two different bunkers. Eight multiparous lactating Holstein dairy cows were used in a replicated 2 × 2 Latin square experimental design and were fed total mixed rations that contained 230 g/kg of either inoculated or control maize silage. Inoculation did not affect the nutritive value or the aerobic stability of the maize silage, but increased the neutral detergent and acid detergent fibre fractions of the silage. However, inoculation increased the concentrations of acetic acid and lactic acid, but reduced ammonia N concentration compared to the control. Cows fed the Lactisil Maize-inoculated silage had a lower DM intake, milk yield, and yields of milk fat and milk protein were lower, compared to control. The digestibility of nutrients was not affected by inoculation. It was concluded that although Lactisil Maize inoculation improved the fermentation quality of high-moisture maize silage, it did not improve aerobic stability of the silage or the production performance of dairy cows compared to the control. _______________________________________________________________________________________
