Role of plant-mediated proteolysis in the degradation of herbage proteins in ruminants
The rapid breakdown of herbage proteins in the rumen and the inefficiency of nitrogen capture by the rumen
microbial population are a major cause of N loss and pollution in pasture based ruminant agriculture. Grazing
ruminants ingest large quantities of living plant biomass, and it is widely assumed that the degradation of plant
protein is entirely carried out in the rumen by proteolytic rumen micro-organisms.
