Effect of Lactobacillus buchneri 40788 on the fermentation, aerobic stability and nutritive value of maize silage
Abstract
The effect of adding Lactobacillus buchneri 40788, a heterofermentative lactobacilli, to whole‐plant maize and its effect on fermentation and aerobic stability of the resulting silage were evaluated. Whole‐plant maize (380 g DM kg–1 fresh weight) was ensiled in laboratory silos after the following treatments: untreated, L. buchneri 40788 at 1 × 105, 2·5 × 105, 5 × 105, and 1 × 106 colony forming units g–1 of fresh forage or, a commercial inoculant containing homolactic acid bacteria, a single species of propionibacteria and enzymes. Addition of L. buchneri 40788 resulted in a decrease in lactic acid concentration but increased the concentration of acetic acid in silage and markedly decreased the numbers of yeasts present in the silage. All levels of L. buchneri 40788, increased the aerobic stability of silages but the effect was greatest for the two highest levels of inoculation. Treatment with the commercial inoculant had no effect on the fermentation or aerobic stability of silage. On‐farm treatment of maize silage with L. buchneri 40788, stored in a bag silo, resulted in changes in fermentation that were similar to those observed in laboratory silos. Treatment decreased the numbers of yeast in silage and increased aerobic stability (+25 h) of the silage when exposed to air. Treatment had no effect on the dry‐matter intake of silage fed to sheep. These results showed that treating silage with L. buchneri 40788 can increase the aerobic stability of maize silage in laboratory and farm silos.

When cattle and sheep are fed silages treated with L. buchneri, dry matter intake is not affected.
“However, available research has shown that when cattle (Driehuis et al., 1999b;Kendall et al. 2002;Taylor et al., 2002;Kung et al., 2003b) and sheep (Ranjit et al., 2002) are fed silages treated with L. buchneri, DMI is not affected.”

The inhibitory effects of acetic acid on yeasts and fungi in silages treated with Lb. buchneri are responsible for the greater aerobic stability of such silages.

Inoculation with P. freudenreichii (1 × 10^4 cfu/g), with or without homolactic bacteria, did not affect propionic acid concentration, yeast and mold counts, or aerobic stability of maize and barley silages.
“Previous studies showed that inoculation with P. freudenreichii (1 × 10 4 cfu/g) with or without homolac-tic bacteria did not affect propionic acid concentration, yeast and mold counts, or aerobic stability of maize and barley silages (Ranjit et al., 2002;Taylor et al., 2002).”

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.
