The ensiling capability of a mixture of sodium benzoate, potassium sorbate, and sodium nitrite
Open accessAbstract
The objective of this study was to evaluate the effects of an additive comprising sodium benzoate, potassium sorbate, and sodium nitrite on the quality of silages fermented from various forage crops. Thirteen crops in 3 groups (differing in dry matter concentration and degree of ensilability) were treated with the additive mixture and compared with untreated control silages. The main focus was on yeast and Clostridia spp. activity in the silages, although other silage quality criteria also were measured. Treated silages from difficult-to-ensile crops at low dry matter were found to have significantly lower silage pH, fewer clostridial spores, and reduced concentrations of ammonia N, butyric acid, and ethanol. In addition, dry matter losses were reduced in treated silages compared with those receiving no additive. Similar results were observed in silages from easy or intermediate ensilable crops when the dry matter concentration was <300 g/kg. When the dry matter concentration was >350 g/kg, the treated silages contained less ammonia N, ethanol, and yeast for 3 out of 4 forages. All treated silages from all crops were aerobically stable during the examination time. The application of the tested additive mixture reduced the growth of undesirable microflora and thereby reduced silage losses and prolonged the aerobic stability of the silages.

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.
