A biochemical model coupled with an iterative nonlinear least-squares program was used to estimate stoichiometric parameters for fermentat ion of soluble carbohydrate, starch, hemicellulose, cellulose and protein in the rumen. [] Key Method Fermentat ion parameters were deduced for two sets of l i terature data, on (1) a roughage group of 60 diets fed to 137 animals and (2) a concentrate group of 48 diets fed to 374 animals. Soluble carbohydrate and starch fermentat ion parameters were much different for the…

An update of a dynamic model of ruminant digestion.
It was concluded that the model can serve as a useful and adaptable tool for analyzing factors affecting nutritive value of feedstuffs and changes in representations of protein metabolism were helpful.
Effect of synchronizing the rate of dietary energy and nitrogen release on rumen fermentation and microbial protein synthesis in sheep
The results are consistent with the view that synchronizing the rate of supply of N and energyyielding substrates to the rumen micro-organisms based upon ingredient in situ degradation data can improve microbial protein flow at the duodenum and the efficiency of microbial protein synthesis.
Prediction of the true metabolizable energy concentration in forages for ruminants
A model has been developed to predict the true metabolizable energy (ME,) concentration in forages given to ruminants. The chemical description of forages is based on the concentrations of ash, crude
Metabolism of the lactating cow: II. Digestive elements of a mechanistic model
Overall stability and sensitivity of the model to individual parameters was generally satisfactory, but the need to improve the description and parameterization of aspects such as particle size in relation to availability, rate and affinity constants for amino acid degradation and rate constants for particle outflow from the rumen was established.
Degradation of starch in feed concentrates by enzymes, rumen fluid and rumen enzymes
The degradation of starch from various feedstuffs was investigated with rumen fluid, α-amylase, pancreatin and a freeze-dried, cell-free preparation of rumen fluid. Rumen fluid was taken from either
Substrate levels, carbohydrate degradation rate and their effects on ruminal end-product formation
The results of the two in vitro experiments clearly point out that rumen VFA proportions and microbial N efficiency are not only affected by the level of different substrates fermented in the rumen but also their degradation rates.
Crude glycerol as glycogenic precursor in feed; effects on milk coagulation properties and metabolic profiles of dairy cows
Changing the glycogenic precursor in animal diet in this way is possible, and may have no immediate deleterious consequences on milk quality or cow health, and there is evidence for benefits from this substitution.
Mathematical modelling and integration of rumen fermentation processes
The models developed in this study provide a basis for the estimation of the profile of nutrients available for absorption, but further consideration of the prediction of type of VFA formed in the rumen should have a high priority.


Microbiological and chemical changes in the rumen during the stepwise adaptation of sheep to high concentrate diets
There was an orderly shift from acid-sensitive to more acid-tolerant species, particularly amongst the lactate-utilizers in response to the gradual decrease in the ruminal pH, allowing the ciliate protozoa to proliferate and regain control of the fermentation.
The fermentation of soluble carbohydrates in rumen contents of cows given diets containing a large proportion of flaked maize

Changes in the concentrations of substrates and products varied widely, owing to the variable basal fermentation, but changes in the proportions of VFA in the rumen were similar to those found in vitro, which suggested the existence of more complex interrelationships among two or more VFA.
Rumen fermentation studies on two contrasting diets. 1. Some characteristics of the in vivo fermentation, with special reference to the composition of the gas phase, oxidation/reduction state and volatile fatty acid proportions
Summary Rumen fermentation characteristics were studied using sheep fitted with rumen cannulae. Diets of 100% hay and 20% hay:80% cooked flaked maize (concentrate diet) were fed at the maintenance
Manipulation of rumen fermentation in sheep by increasing the rate of flow of water from the rumen
SUMMARY The effects of an altered rumen dilution rate (D) upon the molar proportions of volatile fatty acids (VFA) in rumen liquor, VFA production rate, microbial protein synthesis and carbohydrate
Comparative aspects of digestion of four roughages by sheep
The extent and sites of digestion of plant organic matter and its constituent soluble sugars, polysaccharides, pectin, and protein are described for the four roughages and nutritional implications of changes in the site of digestion and of the proportions of nutrients released to the animal are discussed.
Rumen microbial protein synthesis and proportions of microbial and non-microbial nitrogen flowing to the intestines of sheep
It is suggested that efficiency of microbial protein synthesis was dependent on the rate of digesta flow through the rumen, and the apparent digestibility of the non-microbial fraction in the intestines was still appreciable.
Volatile fatty acid metabolism in sheep. 1. Average daily volatile fatty acid production in the rumen of sheep fed lucerne hay.
The total net VFA production was found to be directly proportional to the total VFA concentration in the rumen (correlation coefficient =0,83), and the relationships can be described by the equation y=0,034 x + 0,16 where y=VFA production in moles/12 hour and x=V FA concentration in meq/1.
Measurement of the rates of production of acetic, propionic and butyric acids in the rumen of sheep
Investigation of the findings correlating body-weight increases with the concentration of rumen VFA in lambs on various pastures and the use of isotope dilution techniques offered the most accurate means of measuring production of organic acids in the rumen, since the measurements may be made in vivo and with a minimum of disturbance to the animal.
Dietary induced changes in volatile fatty acid formation from α-cellulose-C14 and hemicellulose-C14.
The effect of dietary changes and associative changes in ruminal microorganisms on volatile fatty acid (VFA) formation from C 14 -labeled polysaccharides was investigated and there was an indication that the randomizing route of propionate formation was more important with ingesta H than withIngesta G.
Rates of production of volatile fatty acids in the rumen. V. Evaluation of fodders in terms of volatile fatty acid produced in the rumen of the sheep
l(a). Volatile fatty acid (VFA) production (moles/12 hr) by two sheep fed at 2-hourly intervals on a constant ration containing equal parts of wheaten hay and lucerne hay, showed no significant
