Abstract

AIM: The mammalian intestinal microflora has been shown to impact host physiology. In cattle, intestinal bacteria are also associated with faecal contamination of environmental sources and human illness via foodborne pathogens. Use of wet distillers' grains with solubles (WDGS) in cattle feed creates a gastrointestinal environment where some bacterial species are enriched. Here, we examine if a diet containing 40% WDGS results in fundamentally different microbial community structures. METHODS AND RESULTS: The 20,002 16S r-RNA gene sequences from 20 beef cattle were analysed using Sanger sequencing methods. At the genus level, Prevotella (Gram negative) and Anaerobacter (Gram positive) were the most frequently occurring bacteria in our beef cattle faecal samples. Diet-associated differences in prevalence were noted for Prevotella but not Anaerobacter. CONCLUSIONS: Diet affects community structure. Faecal communities of co-housed beef cattle are not identical. SIGNIFICANCE AND IMPACT OF THE STUDY: It is known that a diet of 40% corn-based WDGS increases the generic Escherichia coli in the faeces and enriches E. coli O157:H7. The results from the current study suggest that in addition to previously observed changes in E. coli, the entire bacterial community structure is different for animals fed 40% corn-based WDGS compared to a traditional corn-finishing diet.

  • Prevotella, Bacteroides, Ruminococcus, Faecalibacterium, Roseburia and Clostridium are consistently identified in fecal samples from ruminants and are considered part of the core microbiota.

    “Prevotella, Bacteroides, Ruminococcus, Faecalibacterium, Roseburia and Clostridium are consistently identified in fecal samples from ruminants and are considered part of the core microbiota (Dowd et al., 2008; Durso et al., 2012).”

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.
