Abstract

Whole-plant barley (39.4% dry matter) was treated with various chemical and biological additives to assess their effects on silage fermentation and aerobic stability. Treatments were untreated forage, forage treated with several amounts of Lactobacillus buchneri and enzymes (L. buchneri at 1 x 10(5), 5 x 10(5), and 1 x 10(6) cfu/g of fresh forage), forage treated with an inoculant containing (Lactobacillus plantarum, Pediococcus pentosaceus, Propionibacterium freudenreichii, and enzymes), or forage treated with a buffered propionic acid-based additive (0.2% of fresh weight). Sixty-nine d after ensiling, silages treated with L. buchneri and enzymes had lower pH, but had higher concentrations of acetic and propionic acids and higher concentrations of ethanol when compared with untreated silage. Silage treated with the multistrain inoculant containing L. plantarum had lower pH and higher concentrations of lactic acid, but lower concentrations of ammonia-N, neutral detergent fiber, and acid detergent fiber than did untreated silage. The addition of the buffered propionic acid additive resulted in silage with higher concentrations of lactic and acetic acid compared with untreated silage. Numbers of yeasts in all silages were low at silo opening (less than 3.0 log cfu/g) and were numerically the lowest in silages treated with L. buchneri but only treatment with the intermediate and high level of L. buchneri improved the aerobic stability of silage. Because of the altered fermentation pattern, inoculation with L. buchneri, when applied at equal to or more than 5 x 10(5) cfu/g, and enzymes improved the aerobic stability of barley silage.

  • This may be because Lactobacillus brucei can improve the aerobic stability of silage materials during silage.

    “which may be because Lactobacillus brucei can improve the aerobic stability of silage materials during silage [45].”

    From Cellulase Interacts with Lactic Acid Bacteria to Affect Fermentation Quality, Microbial Community, and Ruminal Degradability in Mixed Silage of Soybean Residue and Corn Stover (2021) · cites this paper as [45]

    The Results and Conclusions report that Lactobacillus buchneri improved the aerobic stability of barley silage, particularly at doses of at least 5 × 10⁵ cfu/g. The claim names Lactobacillus brucei instead; our copy does not support that species attribution. (LLM, conf=0.87)

    Experimental — accuracy not yet measured

  • When microorganisms, primarily yeasts, are exposed to air, they consume lactic acid, causing an increase in pH.

    “When microorganisms, primarily yeasts, are exposed to air, they consume this lactic acid, causing an increase in pH [5,35].”

    From Influence of Ensiling Timing and Inoculation on Whole Plant Maize Silage Fermentation and Aerobic Stability (Preliminary Research) (2024) · cites this paper as [35]

    The Discussion states that yeasts can use lactic acid for growth during aerobic exposure and can metabolize it when silage is exposed to air. It does not state that this consumption causes pH to increase; its discussion of pH concerns fermentation before aerobic exposure. The copy does not provide page numbers for these passages. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • In barley silage at 2 g/kg fresh weight, a buffered propionic acid-based additive decreased butyric acid, numerically decreased ethanol, and improved aerobic stability by 244 h compared with untreated.

    “When a buffered propionic acid-based additive was applied to barley silage at 2 g/kg of fresh weight, levels of butyric acid declined (Kung and Ranjit, 2001;Kung et al., 2004), with a numerical decrease in ethanol content and improved aerobic stability of 244 h as compared with untreated silage (Kung and Ranjit, 2001).”

    From Silage review: Recent advances and future uses of silage additives (2018) · cites this paper as Kung and Ranjit (2001)

    The Results report negligible butyric acid in treated silage versus 0.64% in untreated silage. They say BP had no effect on ethanol concentration, rather than reporting a numerical decrease. The Discussion gives the application rate as 0.2% of fresh forage weight (2 g/kg) and says BP-treated silage remained stable for about 240 h longer, not 244 h; the improvement was not statistically significant. Page numbers are unavailable in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • Application of L. buchneri at ensiling improved the aerobic stability of silages in laboratory silos.

    “Experiments in laboratory silos indicated that its application at ensiling improved the aerobic stability of the silages (Driehuis et al., 1999a,b;Filya, 2001Filya, , 2003;;Kung and Ranjit, 2001;Filya et al., 2002;Ranjit et al., 2002;Weinberg et al., 2002).”

    From The Effect of Lactobacillus buchneri and Lactobacillus plantarum on the Fermentation, Aerobic Stability, and Ruminal Degradability of Low Dry Matter Corn and Sorghum Silages (2003) · cites this paper as Kung and Ranjit, 2001

  • L. buchneri 40788 added to forage at harvest has increased acetic acid concentration, lowered yeast numbers, and improved aerobic stability in a variety of silages.

    “Lactobacillus buchneri 40788 is a biological alternative that, when added to forage at harvest, has resulted in an increase in the concentration of acetic acid, a lower number of yeasts, and improved aerobic stability in a variety of silages (Muck, 1996;Weinberg et al., 1999;Kung and Ranjit, 2001).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
