Abstract

This study investigated the effects of an inoculant on silage fermentation, aerobic stability, and the growing and finishing performance of feedlot steers. Whole-crop barley (Hordeum vulgare L.) was chopped, wilted [350–400 g kg−1 dry matter (DM)], and ensiled without (Control) or with (Treated) a bacterial inoculant containing a mixture of Pediococcus pentosaceus, Lactobacillus plantarum, and Propionibacterium freudenreicheii (1.3 × 105 CFU g−1 forage), as well as enzymes applied to fresh forage ensiled in mini or Ag-Bag® silos. Inoculation resulted in a pH decline (P < 0.05) from 6.0 on the day of ensiling to <4.0 after 3 d. In contrast, it required more than 20 d for the pH of the Control silage to fall below 4.0. Inoculant reduced (P < 0.05) the concentration of acetic acid and aerobic stability of silage, as evidenced by a higher (P < 0.05) temperature and pH in aerobically exposed silage. Although the inoculant accelerated pH decline during ensiling, it did not improve the growth performance (P < 0.05) or alter the carcass traits of steers. It is possible that a reduction in the aerobic stability of the inoculated silage may have contributed to this outcome.

  • Less well-defined enzyme cocktails added with a complex mixture of inoculants accelerated the post-ensiling decline in pH but failed to improve the growth performance of steers.

    “In other studies, less well-defined enzyme cocktails added in conjunction with a complex mixture of inoculants accelerated the post-ensiling decline in pH but failed to improve the growth performance of steers (Addah et al., 2016).”

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.
