Journal ArticleDOI
Variability in Characterizing Escherichia coli from Cattle Feces: A Cautionary Tale
Kim Stanford,Tim Reuter,Jennyka Hallewell,Renata Tostes,Trevor W. Alexander,Tim A. McAllister +5 more
TL;DR: Assays for STEC classification may require re-evaluation and/or standardization, and marked changes in stx detection were observed between initial isolation and sub-cultures of the same isolate.
Journal ArticleDOI
Potential for improving fiber digestion in the rumen of cattle (Bos taurus) through microbial inoculation from bison (Bison bison): In situ fiber degradation.
TL;DR: In conclusion, inoculation of cattle with bison rumen contents failed to improve degradation of Fiber from barley straw, canola straw, or timothy hay in cattle well adapted to a barley straw diet, although there were small improvements in the extent of degradation of fiber from alfalfa hay.
Journal ArticleDOI
Expression of a Fibrobacter succinogenes 1,3-1,4-β-glucanase in potato (Solanum tuberosum)
John David Armstrong,G. Douglas Inglis,Lawrence M. Kawchuk,Tim A. McAllister,Fran Leggett,D. R. Lynch,L. Brent Selinger,K.-J. Cheng +7 more
TL;DR: Results of this study demonstrate that a 1,3-1,4-β-glucanase can be expressed in potato tissues, and that potato plants have the potential to be used for the commercial production of heterologous enzymes.
Journal ArticleDOI
286 Structural composition and protein precipitation capacity of condensed tannins from purple prairie clover (Dalea purpurea Vent.).

Journal ArticleDOI
Conserving purple prairie clover (Dalea purpurea Vent.) as hay and silage had little effect on the efficacy of condensed tannins in modulating ruminal fermentation in vitro.
TL;DR: Condensed tannins in PPC decreased protein degradation in vitro, but had minimal effects on overall rumen fermentation, and conservation of PPC as hay or silage had little effect on the efficacy of CT in modulatingRumen fermentation.
