Neogen expands its line of Prima Tech drencher and pour-on guns to include larger capacity versions to administer oral and transdermal treatments to livestock. The Prima Tech 80 ml Drencher and 80 ml Pour-On Gun adjust from 20 ml to 80 ml in 2 ml increments and feature dial-a-dose systems with large finger grips to make dosing changes. As with other Prima Tech veterinary drenchers and pour-on guns, the gun barrel fi lls completely after each shot then pushes from the back. The products’ soft tubing stays fl exible and does not become brittle in cold weather. For more information, visit www.neogen.com.
