● 1st bolus at the first signs of parturition

● 2nd bolus immediately after calving

● 3rd bolus 12 - 24 hours after calving

● 4th bolus 24 - 48 hours after calving

Please discuss protocol with your veterinarian before implementation.

Administration of Bolus

Remove packaging. Place the bolus in the bolus applicator with the rounded end pointing outward. Grab the cow’s upper jaw with your left hand. Keep the cow’s head at a natural position and a little towards yourself. Gently guide the loaded Cal-Boost applicator into the cow’s mouth. When you feel resistance, gently guide the applicator over the tongue. When the applicator is behind the tongue, squeeze the handle to release the bolus. Wait a moment for the cow to swallow and then remove the applicator. Allow access to water.


Not for use in cows for initial treatment of milk fever, with clinical signs of milk fever or laying cows. Do not use broken or damaged boluses.


Store at or below 30°C. Boluses are sensitive to humidity and should be stored in the vacuum sealed plastic until immediately before use.

Attention! Do not use broken or damaged boluses.
