Journal ArticleDOI
Effect of Bioaugmentation with Anaerobic Fungi Isolated from Ruminants on the Hydrolysis of Corn Silage and Phragmites australis
Bhargavi Ravi,Valentine Nkongndem Nkemka,Xiying Hao,Jay Yanke,Tim A. McAllister,Hung Lee,C. Veluchamy,Brandon H. Gilroyed +7 more
TL;DR: While some microbial activity was observed, inoculation with anaerobic fungi did not result in any significant difference in the degradation of either type of plant biomass tested, likely due to low fungal activity or survival under the experimental conditions tested.
Journal ArticleDOI
Effect of essential oil blends and a nonionic surfactant on rumen fermentation, anti-oxidative status, and growth performance of lambs
TL;DR: In this paper, the effect of essential oils (OEO; XEO) and an emulsifier on rumen fermentation, anti-oxidative status, and the growth performance of lambs was evaluated.
Journal ArticleDOI
Effect of Forage Types Differing in Undigested Neutral Detergent Fiber Concentration and Forage Inclusion Rate on Reticulo-Ruminal Motility and Fermentation, Total Tract Barrier Function, and Blood Metabolites of Finishing Beef Heifers.
Murillo C Pereira,Wenzhu Yang,Karen A. Beauchemin,Tim A. McAllister,K. M. Wood,Gregory B Penner +5 more
TL;DR: This article evaluated the effects of the forages (barley silage [BarS] vs. straw [STR]) that differ in the undigested neutral detergent fiber (uNDF) concentration and forage inclusion (FI) rate on ruminal fermentation, total tract barrier function, reticulo-ruminal motility, and blood metabolites of beef heifers.
Journal ArticleDOI
Genomic Characterization of Enterococcus hirae From Beef Cattle Feedlots and Associated Environmental Continuum
Sani-e-Zehra Zaidi,Rahat Zaheer,Ruth Barbieri,Shaun R. Cook,Sherry J. Hannon,Calvin W. Booker,Deirdre L. Church,Gary Van Domselaar,Athanasios Zovoilis,Tim A. McAllister +9 more
TL;DR: E. hirae had unique genes associated with vitamin production, cellulose, and pectin degradation, traits which may support its adaptation to the bovine digestive tract, andAntimicrobial resistance profiles of E.hirae isolates recovered from different environmental settings appeared to reflect the kind of antimicrobial usage in beef and human sectors.
