Control of Escherichia coli O157 on beef at 37, 22 and 4 °C by T5-, T1-, T4-and O1-like bacteriophages
Hui Liu,Yan D. Niu,Ruiqiang Meng,Jiaying Wang,Jinquan Li,Roger P. Johnson,Tim A. McAllister,Kim Stanford +7 more
TL;DR: As the beef supply chain includes hours of storage or transport at temperatures near 4 °C, this study demonstrates phages could significantly reduce E. coli O157 at warmer temperatures and high MOI.
Journal ArticleDOI
Targeted 16S rRNA high-throughput sequencing to characterize microbial communities during composting of livestock mortalities.
Victoria L. Tkachuk,Denis Krausé,Natalie C. Knox,A.C. Hamm,Francis Zvomuya,K. H. Ominski,Tim A. McAllister +6 more
TL;DR: A comprehensive understanding of the microbial community is necessary to ensure a significant reduction in pathogens during the composting process, and this work aims to provide guidance on how to best manage this community.
Journal ArticleDOI
Effect of purple prairie clover (Dalea purpurea Vent.) hay and its condensed tannins on growth performance, wool growth, nutrient digestibility, blood metabolites and ruminal fermentation in lambs fed total mixed rations
Kai Peng,Kai Peng,Danielle C. Shirley,Z. Xu,Qianqian Huang,Qianqian Huang,Tim A. McAllister,Alex V. Chaves,Surya Acharya,Cailing Liu,Shunxi Wang,Yuxi Wang +11 more
TL;DR: This paper evaluated the effects of purple prairie clover (PPC, Dalea purpurea Vent.) hay and its condensed tannins (CT) on feed intake, growth performance, wool growth, nutrient digestibility, blood metabolites and rumen fermentation in lambs fed diets containing PPC and alfalfa hay.
Journal ArticleDOI
Greenhouse gases in animal agriculture—Finding a balance between food production and emissions
TL;DR: The 2010 GHG in Animal Agriculture Conference in Banff (Alberta, Canada) as mentioned in this paper addressed microbial aspects of ruminal CH4 production, and methods to measure GHG from livestock and manure.
Journal ArticleDOI
Effects of tannic acid and quebracho tannins on in vitro ruminal fermentation of wheat and corn grain
TL;DR: Tannins are likely to be more effective at modulating the rate of starch digestion in grains that possess a readily degradable protein matrix, as well as in response to similar concentrations of tannins.
