Anthropogenic CH₄ emissions are widely recognised as a world wide problem due to their global warming potential and because they represent a loss of dietary energy to ruminants. Few recent studies have examined medium or long term effects of methanogen inhibitors on rumen functional parameters and...

Rate of barley starch digestion in the rumen is critical issue in high-grain fed beef cattle because it is associated with growth performance and health. The digestion rate of starch varies with variety, grain processing or starch content. The objectives of this study were to evaluate the effect of ...

There is limited knowledge on the effect of barley silage (BS) with different ruminal in vitro neutral detergent fiber digestibility (ivNDFD) on dairy cow performance and chewing activity. The objective of this study was to assess the effects of BS varieties selected for varying rates of ivNDFD on...

We hypothesized that inoculating the rumen of beef cattle with rumen contents of bison and supplementing with exogenous fibrolytic enzymes (FE) would improve ruminal feed digestibility by enhancing microbiome activity in the rumen. The objectives of this study were to evaluate the effects of...

The ability of ruminants to convert plant biomass unsuitable for human consumption into meat and milk is of great societal and agricultural importance. However, the efficiency of this process is largely dependent on the digestibility of plant cell walls. Supplementing ruminant diets with exogenous...

Fecal nutrients and apparent total tract digestibility (ATTD) were predicted using near-infrared spectroscopy (NIRS) of feces collected from the pen floor or the rectum of feedlot cattle in 2 studies, and pen floor samples were assessed for their ability to predict NE_g, ADG, and G:F. In study 1,...
