Ruminal Stasis

• Usually related to a disturbance of neural control e.g.
  • CNS depression (anaesthetics, pain, pyrexia)
  • Decreased excitatory (anorexia, vagus indigestion) input from forestomach receptors
  • Increased inhibitory (distension, acidosis) input from forestomach receptors
  • Motor blockade (hypocalcaemia).
