Abstract

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...

Abstract

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...

Abstract

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 NEg, ADG, and G:F. In study 1,...

Abstract

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...
