A Longitudinal Study of Antimicrobial Resistance in Enterococcus spp. Isolated from a Beef Processing Plant and Retail Ground Beef
Devin B. Holman,Cassidy L. Klima,Katherine E. Gzyl,Rahat Zaheer,Tineke H. Jones,Tim A. McAllister +5 more
TL;DR: In this paper, the authors used enterococci as indicator bacteria for monitoring AMR in a commercial beef packaging facility and in retail ground beef over a 19-month period, and found that E. faecalis was the most frequently isolated species followed by Enterococcus hirae.
Journal ArticleDOI
Effect of dry or temper rolling of high or low protein wheat and its impact on rumen parameters, growth performance, and liver abscesses in feedlot cattle.
Amanda C Meadows,Stephanie A. Terry,Gregory B Penner,Pierre Hucl,Tim A. McAllister,Gabriel de Oliveira Ribeiro +5 more
TL;DR: In this article , the impact of dry (DR) vs. temper rolled (TR) and low (13, LP vs. high protein (18, HP) wheat on ruminal fermentation, growth, and liver abscesses in feedlot cattle was assessed.
Journal ArticleDOI
Modelling environmental impacts associated with the removal of productivity-enhancing technologies from Canadian feedlots: a case study
Emily M Boonstra,I.F. Aboagye,Tim A. McAllister,Getahun Legesse,G. Mengistu,D. L. Fulawka,Marcos R. C. Cordeiro,Gabriel O Ribeiro,E. J. McGeough,K. H. Ominski +9 more
TL;DR: In this paper , the authors have shown that conventional beef production systems have a lower environmental footprint than non-conventional systems, and they have also demonstrated that conventional Beef production systems are more efficient in terms of land and water use.
Journal ArticleDOI
Composition and Protein Precipitation Capacity of Condensed Tannins in Purple Prairie Clover (Dalea purpurea Vent.).
Qianqian Huang,Qianqian Huang,Tianming Hu,Z. Xu,L. Jin,Tim A. McAllister,Surya Acharya,Wayne E. Zeller,Irene Mueller-Harvey,Yuxi Wang +9 more
TL;DR: In this paper, the authors determined the concentration and composition of condensed tannins (CT) in different tissues of purple prairie clover (PPC; Dalea purpurea Vent.) at different maturities and to determine their protein-precipitating capacity.
Journal ArticleDOI
Effect of sod-seeding bloat-free legumes on pasture productivity, steer performance, and production economics
B.M. Kelln,Gregory B Penner,Surya Acharya,Tim A. McAllister,K. Larson,John J McKinnon,Bill Biligetu,Herbert Lardner +7 more
TL;DR: In this paper , sod-seeding sainfoin and cicer milkvetch into monoculture grass (Lanigan, SK) or legume (Lethbridge, AB) stands on pasture productivity, steer performance, and economics was evaluated.
