  1. Rumination monitoring as a Management tool for early detection of metabolic disorders N. E. Engwall, K. N. Carraway Clemson University

  2. Overview-Rumination • Reduce particle size • Enhance digestibility • Increase saliva • Buffer rumen • Improve rumen health • Happy cows Source: Memorial University

  3. Overview-Metabolic Disorders • Ketosis • 10-15% all fresh cows • Displaced Abomasum • 80% within first month lactation • Ruminal Acidosis • First 60 days in lactation highest risk Source: My Dairy Vet

  4. Rumination Monitoring • HR-Tag rumination monitoring system • Loggers • Readers • Software Source: SCR Engineers Ltd

  5. Monitoring for Metabolic Disorders • Transition animals • Visual Observation vs. Rumination Monitoring • Trial validates accuracy • Health Report • Run tests to narrow down • Monitor treatment Source: Progressive Dairy

  6. Progression of Health Reports Source: SCR Engineers Ltd.

  7. Progression of Health Reports Source: SCR Engineers Ltd.

  8. Limitations and Improvements • Must be near the reader • Proper placement of tag necessary Source: SCR Engineers Ltd.

  9. Limitations and Improvements • Large start up costs • Not always associated with illness

  10. Summary • Rumination monitoring valuable tool • HR-Tag replaces visual observer • Health Reports detect early signs of disease • Save $ with treatments
