How to Administer a Bolus

General Guidance

  • Administer to adult cattle weighing over 150kg live weight ONLY.
  • Two EnduraBol™ Cattle boluses should be given to each animal.
  • Before bolusing, the animal should be securely restrained.

Application Instructions

Load Applicator

  • Insert the flat end of the boluses into the chamber first.
  • Ensure both the boluses are securely held in the chamber of the applicator.

Inserting the applicator

  • Place the bolus end of the applicator into the centre of the cow’s mouth, to the back of the tongue.
  • Ensure the cow’s head and neck are extended in a straight line.


  • Severe pressure on the tongue.
  • Using force damaging teeth or any soft tissue.

Bolus Release

  • Gently squeeze the trigger, releasing the boluses over the back of the tongue.
  • Once the boluses have been ejected, further progress will depend on the swallowing reflex of the animal, the animal should easily be able to swallow the boluses.
  • Avoid using force which can cause damage to soft tissue.
  • Carefully remove the applicator, maintaining its central position in the mouth.
