26mm™ Multi-dose Balling Gun and T-Spec™ 106 Oral Speculum

1. Properly restrain animal, such as with a locking head gate as pictured.

2. Only open QuadriCal® MINI package when ready to give to cows. Open package using easy-tear notch.

3. Put boluses into proper sized balling gun, such as the 26mm™ Multi-dose balling gun, so rounded end of bolus is facing out and goes into cow first.

4. Place fingers into cow’s mouth in gap between front incisor and rear molar teeth. Open cow’s mouth with gentle pressure from your hand.

5. With the cow’s head at a slight downward angle, insert the balling gun into the center of the mouth and gently advance just past the base of the tongue.

6. Raise the cow’s head slightly and advance the plunger of the balling gun slowly to discharge boluses at back of cow’s mouth, allowing cow time to swallow each bolus.

When using a speculum, position the speculum as described for a balling gun, except place the boluses, rounded end first, into the rear of the speculum after speculum is properly positioned at the rear of the cow’s mouth.

Note: When using hard boluses and gelatin capsules together, place the capsules into the equipment last to prevent broken capsules. Never administer broken boluses or capsules.


Store below 85° F, preferably at room temperature, in original packaging. Do not expose to air until time of use.
