How to Administer a Bolus

General Guidance

Administer to adult cattle weighing over 150kg live weight ONLY.
Two EnduraBol® Pre-Calver 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.

Avoid:

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.
