Fate of metabolic hydrogen in the rumen.
Introduction T h e first axiom of ruminology appears to be: ‘The rumen is a strictly anaerobic system’ (Hungate, 1966) but before we accept this we should examine the evidence for and against this assertion. Probably the strongest evidence for anaerobiosis comes from the studies of the reactions in the rumen, from the stoichiometries observed and from the low oxidation-reduction potential obtai...
متن کاملMetabolic fate of cysteine and methionine in rumen digesta.
Estimates were obtained of the extent to which cysteine and methionine were incorporated into the protein of the microbes of rumen digesta without prior degradation and resynthesis. By using the amino acids labeled with both (35)S and (14)C, it was observed that a large proportion of the (35)S appeared in the sulfide pool and of the (14)C appeared in volatile fatty acids. By isolating the appro...
متن کاملRumen passage rates and
Six ruminally cannulated steers were used to evaluate the influence of dietary concentrate level on digestion of fiber, rumen pH and fill, and liquid and particulate passage rates. Total tract digestibility of potentially digestible fiber, but not total fiber, was decreased with each increase in concentrate level. Digestion coefficients suggest that potentially digestible fiber is a more approp...
متن کاملRumen Physiology for the Rancher
The ruminant animal has two unique features – it chews its cud and has four distinct compartments in the stomach. More importantly the ruminant can convert forages that are comprised by large quantities of cellulose, that is poorly digestible by non-ruminants, into high quality protein (muscle) that provides excellent eating experiences and nutrients for humans. Rumen Physiology is the study of...
متن کاملRumen Protozoa - Potential for Manipulation
The manipulation of rumen function through the removal of the ciliate protozoa has not resulted in consistent changes in ruminant production. Current research findings are discussed with particular emphasis given to the role of protozoa in fibre digestion in the rumen and the availability of protein for intestinal digestion. Dietary conditions under which positive responses to defaunation can b...
