Introduction

  • Sodium, potassium (and chloride) are intrinsically interlinked in terms of their metabolism and function in animals.
  • These major minerals all play a critical role in maintaining osmotic pressure, acid-base balance (especially in the rumen via salivary sodium bicarbonate) and water metabolism.
  • Due to these critical roles, sodium (or salt) deficiency can have severe harmful effects on animal health and production.
