Abstract

Chemical and microbiological changes occurring during aerobic exposure of maize silages and their influence on dry matter (DM) intake and preference by goats were evaluated. Eight maize silages differing in DM content, chopping length and compaction pressure were used for the study. After opening, silages were exposed to air for 8 days (d). In 2-d intervals, silage was stored anaerobically for use in preference trials. During the experimental phase, each possible two-way combination of the five silages (d0, d2, d4, d6 and d8) and one standard lucerne hay, was offered as free choice to six goats. Generally, a significant decline occurred in DM intake after 4 d of aerobic exposure. After 8 d, mean decrease in intake was 53% in comparison to the fresh silages. Preference when expressed as DM intake was negatively correlated to silage temperature (as difference to ambient), ethanol and ethyl lactate.

  • Pooling data from three experiments (Gerlach et al., 2013, 2014a,b), a negative relationship between mold count of the offered forage and DMI by goats can be observed.

    “Pooling data from these 3 experiments (Gerlach et al., 2013, 2014a,b), a negative relationship between mold count of the offered forage and DMI by goats can be observed (Figure 7).”

    From Silage review: Factors affecting dry matter and quality losses in silages (2018) · cites this paper as Gerlach et al., 2013

    The Microbiological analysis and Animal preference and dry matter intake sections report that mould counts rose during aerobic exposure and that goats’ DMI fell with prolonged exposure. But this paper does not report a negative relationship between mould count and DMI or an analysis pooling the three cited experiments; its reported negative DMI relationship is with silage temperature. (LLM, conf=0.78)

    Experimental — accuracy not yet measured

  • Silage temperature during aerobic exposure (expressed as difference to ambient temperature, ΔT) was the best predictor of DMI, intake being greatest in silages with the lowest ΔT.

    “Silage temperature during aerobic exposure (expressed as difference to ambient temperature, ΔT) was the best predictor of DMI, intake being greatest in silages with the lowest ΔT (Figure 6).”

  • Gerlach et al. (2013) reported an average 53% reduction in DMI of corn silages exposed to air for 8 d before being offered to goats in a preference trial.

    “More recently, Gerlach et al. (2013) reported an average 53% reduction in DMI of corn silages exposed to air for 8 d before being offered to goats in a preference trial.”

  • Improper incorporation of deteriorated feed from the top layers of the silo into the feed mixer could potentially reduce DMI and dairy cow performance.

    “and (2) could potentiality reduce DMI (Gerlach et al., 2013) and dairy cow performance (Hoffman and Ocker, 1997).”

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.
