Abstract The Cornell Net Carbohydrate and Protein System (CNCPS) has a kinetic
submodel that predicts ruminal fermentation. The ruminal microbial population is divided …

In the mid-1970s, ionophores were approved by the Food and Drug Administration for
addition to the rations of ruminants in the United States. Monensin has been used most …

Nitrogen metabolism is reviewed with emphasis on methods for quantitating various
nitrogen-transactions in the rumen of animals on a variety of diets. Ammonia kinetics …

Microbial fermentation of carbohydrates in the hindgut of dairy cattle is responsible for 5 to
10% of total-tract carbohydrate digestion. When dietary, animal, or environmental factors …

Fourteen young wether sheep were fed freshly cut Lotus pedunculatus as a sole diet to
examine the effects of condensed tannins (CT; 55 g/kg lotus DM) on nitrogenous aspects of …

The way in which the rumen has evolved as their first digestive organ potentially affords
ruminants an efficiency of protein nutrition that is not available to non-ruminant herbivores …

This book brings together the latest research on protein absorption by ruminants and takes a
look at the calculation of optimum nutrient requirements, including bacterial digestion, in the …

The objective of this experiment was to investigate the effect of level of dietary concentrate
on rumen fermentation, digestibility, and N losses in lactating dairy cows. The experiment …

Mixed rumen bacteria were incubated in media containing salts, ammonia, vitamins, volatile
fatty acids, sulfide, and casein. When initial cell density was 1.0 absorbance unit and mixed …

Nitrogen metabolism of ruminant animals has been the subject of thousands of research
publications. Study of ruminai and intestinal function continues. The quantitative and …
