Abstract

In grazing ruminants, where herbage enters the rumen directly from pasture, rumen micro-organisms are reported to be responsible for the entire proteolytic process causing initial and rapid degradation of plant proteins to lower molecular weight peptides and amino acids (and ultimately deamination of the breakdown products to ammonia). It is our contention that this is wrong and that protein breakdown in grazing ruminants is under the control of plant vacuolar proteases which become active upon plant cell death following ingestion of grazed herbage. The research covered in this project will investigate the above hypothesis and determine the extent to which plant vacuolar proteases contribute to proteolysis in grazing animals. The research is collaborative with IGER studies in plant cell biology (Professor H. Thomas) and strategic studies under MAFF DS0307.
