Effect of inhibitor concentration and end-product accumulation on estimates of ruminal in vitro protein degradation.
Effects of varying the concentrations of hydrazine sulfate (HS) and chloramphenicol (CAP), inhibitors of microbial-N uptake and protein synthesis, on rates of protein degradation estimated from net appearance of NH3 and total amino acids (TAA) were studied in a ruminal in vitro fermentation system. Without inhibitors, recoveries of N added as NH3 and TAA were 4 and 6% after 4-h incubations, and...

Ruminal fermentation pattern, bacterial population and ruminal degradation of feed ingredients as influenced by ruminal ammonia concentration.
The effects of ruminal ammonia concentration on bacterial numbers, fermentation pattern and degradation of feed ingredients in the rumen were examined with three nonlactating Holstein cows fitted with ruminal cannulas. Cows were fed twice daily a complete mixed diet (90% whole plant oat silage and 10% concentrate mixture) containing 11.1% CP on a DM basis. Ammonium bicarbonate (NH4HCO3) was inf...

Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...
