What is the primary use of boluses in veterinary medicine?

Boluses are primarily used in veterinary medicine for administering medications or supplements to large animals, typically using a device known as a balling gun. This method is practical because boluses are solid doses that can be easily given to large animals, which may resist other forms of medication delivery.

The design of a bolus allows it to be swallowed whole, and once in the animal’s stomach, it dissolves to release the medication over time. This is especially beneficial in large animal practice, where efficient and effective administration of medication is crucial for the animal’s health and wellbeing.

Other options focus on specific categories of animals or forms of medication administration that do not reflect the primary use of boluses. Therefore, using a balling gun to administer boluses to large animals is the most accurate description of their primary application in veterinary medicine.
