Oral Medications

When giving pills or liquid medication by mouth, restrain the animal in a chute with a head catcher, or tie its head to the side of the chute so it cannot swing its head away or hit you with its head while trying to avoid the medication.

Pills
Pills and boluses can be given with a balling gun. A balling gun is a long-handled tool that holds the bolus while you put it toward the back of the mouth. When you press the plunger it pushes the pill out of its slot into the animal’s throat to be swallowed. If you aim it far back, the animal must swallow the pill when the tool releases it. The tool keeps your fingers from being crushed by the animal’s teeth.

Be careful when giving pills or examining the inside of an animal’s mouth. Cattle have no top teeth in front but can crush your fingers between molars if your fingers are back too far when the animal bites down.

Liquids
Giving liquid medications (or pills dissolved in water) to a calf is easy with a large syringe (minus the needle) or a special dose syringe with a metal tube that goes to the back of the mouth. Position the syringe into the corner of the mouth and aim it far back so the calf must swallow the medication.

If you’re giving a large dose (such as several ounces of Pepto Bismol or Kaopectate), do not squirt it all at once; he may be able to spit some back out, or he may choke on it. Squirt a little at a time, allowing him to swallow each portion before you squirt in more. Keep his head tipped up so medication can’t run back out of his mouth. You can refill the syringe as needed for a large dose.
A small calf can be backed into a fence corner and his head held securely between your legs as you do this, whereas a large calf must be restrained more fully in a chute or with someone helping you hold him. It’s difficult to give liquid medication to an adult animal unless you use a stomach tube, and you will need your veterinarian’s help to be sure it goes down the throat and not the wind pipe.
