The VetGun uses precision-engineered CO2 power to project a precise dosage of AiM-L VetCap to treat the animal, without any handling at all.The VetCap is a patented new dosage form that encapsulates liquid parasiticides in a special softgel capsule. It is delivered using SmartVet's VetGun delivery system. The VetGun is designed to fire the VetCaps out to a range of about 30 feet. The VetCap bursts on the cow, releasing its contents; the formulation then goes to work in a similar way to pour-on products. The VetGun and VetCaps are engineered not to startle the cattle, and minimize any discomfort caused by the dosing process. Includes two adaptors, allowing use with both 25 gm and 90 gm CO2 propellant cartridges.
