Ear tag Applicators are in Plastic, metal or mixed of both. Based on the type of ear tag, applicators are with needle or without.
Using applicators are very easy. Briefly, you must install tag on the applicator correctly, place the applicator on the correct area of ear and then press it. Then tag will be installed on ear.
Applicators must be designed ergonomic, safe for animal and user and enough strong for farm usage.
To reduce farm expenses, needle can be changed easily if it is damaged or broken. It means the farmer doesn't need to buy a new one if handles are in good condition.
Although the applicator is used for installing tags, however please pay attention that it can transmit disease easily if it's contaminated with animal blood. So please disinfect applicator after use and before tagging each animal with normal detergent.
