Journal ArticleDOI
Characterization of rumen bacterial diversity and fermentation parameters in concentrate fed cattle with and without forage.
TL;DR: To determine the effects of the removal of forage in high‐concentrate diets on rumen fermentation conditions and rumen bacterial populations using culture‐independent methods.
Journal ArticleDOI
Bacterial and fungal core microbiomes associated with small grain silages during ensiling and aerobic spoilage.

TL;DR: Next Generation Sequencing was successfully used to describe bacterial communities and the first record of fungal communities throughout the process of ensiling and utilization, which could lead to improved ensiling practices and the selection of silage inoculants that act synergistically with the natural forage microbiome.
Journal ArticleDOI
Sensitivity of Escherichia coli to Seaweed (Ascophyllum nodosum) Phlorotannins and Terrestrial Tannins
TL;DR: The bacteriostatic and bactericidal effects of phlorotannins isolated from Ascophyllum nodosum (brown seaweed) on Escherichia coli O157:H7 investigated are superior to that of terrestrial tannins purified from Quebracho and from Rhus semialata.
Journal ArticleDOI
Effect of dietary or abomasal supplementation of exogenous polysaccharide-degrading enzymes on rumen fermentation and nutrient digestibility.
TL;DR: These two experiments showed that abomasal supplementation of EPDE did not successfully supply cellulases and amylases to the intestine, due partially to their limited resistance to low pH and pepsin proteolysis.
Journal ArticleDOI
Assessment of the sulfur hexafluoride (SF6) tracer technique for measuring enteric methane emissions from cattle.
TL;DR: There was a trend for greater accuracy and precision of the SF6 tracer technique when used with cattle fed a high forage diet at a restricted level of intake, suggesting theSF6 tracers technique is most reliable for the grazing system.
