Kim Stanford,Tim A. McAllister,Yan D. Niu,T. P. Stephens,Amanda Mazzocco,Thomas E. Waddell,Roger P. Johnson +6 more
TL;DR: Two successful systems for delivery of Ephage were developed, but a better understanding of phage-E.
Journal ArticleDOI
Evidence of Increased Diversity of Methanogenic Archaea with Plant Extract Supplementation
S. Ohene-Adjei,Alexandre V. Chaves,Tim A. McAllister,Chaouki Benchaar,Ronald M. Teather,Robert J. Forster +5 more
TL;DR: The phylogenetic analysis indicated a trend toward an increased diversity of methanogenic archaea related to Methanosphaera stadtmanae, Methanobrevibacter smithii, and some uncultured groups with cinnamaldehyde, garlic, and juniper berry oil supplementation.
Journal ArticleDOI

H. Henry Janzen,Denis A. Angers,M. Boehm,M. A. Bolinder,Raymond L. Desjardins,J.A. Dyer,Benjamin H. Ellert,D. J. Gibb,Edward G. Gregorich,Bobbi L. Helgason,Reynald Lemke,Daniel I. Massé,Sean M. McGinn,Tim A. McAllister,Nathaniel K. Newlands,Elizabeth Pattey,P. Rochette,Ward Smith,A.J. VandenBygaart,Hong Wang +19 more
TL;DR: This work proposes to develop a “Virtual Farm”, a series of interconnected algorithms that predict net emissions from flows of carbon, nitrogen, and energy, and describes an approach for identifying practices that best reduce net, whole-farm emissions.
Journal ArticleDOI
Effects of phlorotannins from Ascophyllum nodosum (brown seaweed) on in vitro ruminal digestion of mixed forage or barley grain
TL;DR: In this article, the effect of phlorotannins from the seaweed Ascophyllum nodosum on ruminal fermentation of mixed forage or barley grain was investigated.
