Abstract

The silage quality of Manyflower silvergrass with microalgae supplementation was investigated, and the variation in bacterial communities during ensilage period was analyzed by high-throughput sequencing technology. In addition, the specific methane yields of the silages were also evaluated. Results showed that the samples with microalgae supplementation have lower pH value and higher lactic acid concentration (8.0 mg/g FM). Meanwhile, higher NH3-N concentration was observed since microalgae were N-rich material. Microalgae additions also influenced the bacterial community structure. For the samples without microalgae, the major genus was Enterococcus from day 1 to day 3, and then Lactobacillus became the dominant genus. While the prevalent genus represented in the samples with microalgae supplementation was Lactobacillus. The specific methane yields of all samples were within the range of 153 ± 1 mL/g VS to 178 ± 11 mL/g VS and no significant difference was observed.

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.
