Methods to estimate ruminal protein and carbohydrate availability were reviewed. Solubility
of carbohydrate and protein is dependent on the chemical characteristics of the buffer …

Abstract In the United States, cattle are commonly fed diets containing cereal grains. The
presence of starch and sugars reduces fiber digestion, which may in turn depress intake. In …

Direct microscopic examination of the rumen and its contents shows microbial populations
largely attached to feed particles in the digesta. Most feeds contain a surface layer that is …

The degradation of plant cell walls by ruminants is of major economic importance in the
developed as well as developing world. Rumen fermentation is unique in that efficient plant …

Publisher Summary The chapter focuses on the recent advances in understanding the
structural and functional organization of individual cellulases, their regulation, and the ways …

Simple Summary Starch and cellulose are the principal components in diets for dairy cows
worldwide, providing the primary energy to the rumen microorganisms as well as the host …

We divided the adhesion process of the predominant cellulolytic rumen bacteria Fibrobacter
succinogenes, Ruminococcus flavefaciens, and Ruminococcus albus into four phases: 1) …

The processes by which cellulases hydrolyse cellulose are a function of substrate reactivity
as well as enzyme activity. The two must be considered together if an accurate description of …

Molecular diversity of rumen bacteria was analyzed by PCR amplification and sequencing of
16S rDNA clone libraries prepared from the rumen content of Holstein cows fasted for 16 h …

The bacteria Fibrobacter succinogenes, Ruminococcus flavefaciens, and Ruminococcus
albus generally are regarded as the predominant cellulolytic microbes in the rumen …
