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...

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,...

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...

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...
