Break parasite life cycles with the SAFE-GUARD Program
95% of parasites are found in the pasture3 and continue their cycle of infection when ingested during grazing. Following the SAFE-GUARD Program in the spring, summer and fall effectively kills parasites and disrupts the shedding cycle.

Straight to the gut:
the fenbendazole difference

SAFE-GUARD is the only dewormer on the market using fenbendazole as its active ingredient. Fenbendazole is a unique molecule known for its broad-spectrum, fast-acting ability to kill parasites.

Unlike pour-ons and injectables, the oral administration of SAFE-GUARD takes it right to the gut to fight parasites where they live.

As a member of the benzimidazole class, SAFE-GUARD remains powerful while resistance grows against endectocides, like Ivermectin and Doramectin.

Find the right dose for your herd
Take the fight to the pasture
Deworming in the summer or during grazing doesn’t have to be labor and stress intensive. SAFE-GUARD feed formulations save you time and labor costs by adding a chute-free deworming option.

SAFE-GUARD feed formulations include options your herd is already used to, like block, pellets and cubes.

Feed formulations demonstrate the same leading efficacy rates as other SAFE-GUARD product options.
