Shop trusted cattle equipment selected for farms, alongside compatible cattle bolus products and practical livestock health essentials.

Choosing the Right Cattle Bolus Gun

Bolus guns are not necessarily interchangeable. The diameter, length and delivery mechanism of the applicator must suit the specific bolus being administered. Using an unsuitable applicator can make loading and release difficult and may prevent controlled placement.

• Check bolus diameter: Our range includes applicators designed for different bolus sizes, including standard 23 mm and larger 29 mm cattle boluses. Always check the individual bolus specification before selecting an applicator.
• Check manufacturer compatibility: Some applicators are designed for a particular manufacturer's supplementation or treatment system rather than universal use.
• Consider repeated use: For routine herd dosing, choose a robust, reusable applicator that can be thoroughly cleaned and inspected between sessions.
• Prioritise controlled handling: A well-designed applicator should allow smooth loading and release, helping the operator place the bolus correctly without unnecessary force.

If you already know which supplement your cattle require, start with the manufacturer's recommended applicator. Our Agrimin Bolus Gun is designed for compatible 29 mm cattle boluses, while other applicators in the range accommodate different dimensions and dosing systems.

Technical Specifications and Care

A cattle bolus is commonly used to deliver nutritional supplements and trace elements over a specified period, making bolus administration a useful part of planned herd management. Requirements can differ according to diet, forage analysis, age, production stage and individual animal needs, so supplementation should be based on appropriate professional advice rather than used as a substitute for diagnosis or veterinary treatment.

Correct hygiene is equally important. Remove visible contamination from reusable equipment after dosing and clean it according to the manufacturer's instructions. Allow the applicator to dry before storing it somewhere clean and protected from damage. Inspect the barrel, head and delivery mechanism before reuse and replace damaged equipment.

Pro tip: Before starting a batch of cattle, load one bolus and check that it sits correctly and releases smoothly from the applicator. Never compensate for poor compatibility by forcing a bolus through the gun. Keep equipment used for dosing clean between animals to support good farm hygiene and biosecurity.

Frequently Asked Questions

What size cattle bolus gun do I need?

Match the applicator to the diameter and type of bolus you are administering. Cattle boluses can require different applicators, including 23 mm and 29 mm models. Always check the bolus manufacturer's compatibility instructions before use.

How do you use a cattle bolus gun?

Load the compatible bolus into the applicator and follow the manufacturer's administration instructions carefully. Correct restraint, positioning and placement are important. Never force the applicator or bolus if resistance is encountered.

Can you use the same bolus gun for different cattle boluses?

Only when the applicator is specifically compatible with each product. Bolus dimensions and applicator designs vary between manufacturers, so never assume one cattle bolus gun will safely administer every cattle bolus.
