Journal ArticleDOI
Prevalence and Impact of Bacteriophages on the Presence of Escherichia coli O157:H7 in Feedlot Cattle and Their Environment
TL;DR: The prevalence of phage fluctuates in a manner similar to that described for E. coli O157:H7 if cattle in the pen harbored phage, and was more prevalent in manure slurry than other environmental sources.
Journal ArticleDOI
A third-generation esterase inoculant alters fermentation pattern and improves aerobic stability of barley silage and the efficiency of body weight gain of growing feedlot cattle
TL;DR: Inoculation of whole-crop barley silage with a mixed culture of homolactic lactic acid-producing bacteria and FAE-producing L. buchneri at ensiling improved aerobic stability of the silage and efficiency of BW gain of growing feedlot steers.
Journal ArticleDOI
Long-Haul Transport and Lack of Preconditioning Increases Fecal Shedding of Escherichia coli and Escherichia coli O157:H7 by Calves†
TL;DR: The calves' susceptibility to infection from the environment (possibly the holding facilities or feedlot pens) was likely elevated by the stresses of weaning, transport, and relocation and preconditioning may serve to reduce E. coli O157:H7 shedding by range calves on arrival at the feedlot.
Journal ArticleDOI
Effect of full-fat hemp seed on performance and tissue fatty acids of feedlot cattle
TL;DR: Levels of HS up to 14% of dietary DM exerted no detrimental effect on the growth or feed efficiency of cattle as compared to cattle fed a standard barley-based finishing diet.
Journal ArticleDOI
Comparison of the fermentation characteristics, aerobic stability and nutritive value of barley and corn silages ensiled with or without a mixed bacterial inoculant
TL;DR: A comparison of the fermentation characteristics, aerobic stability and nutritive value of barley and corn silages ensiled with or without a mixed bacterial inoculant in western Canada shows that the relative value of these two forages in feedlot diets or their responses to inoculation have not previously been compared.
