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.

For Cow-Calf Producers

Spring Turnout

If a fall deworming treatment was not given, deworm at turnout or grass green-up. If a fall treatment was given after the first frost, deworm the adult cow and her suckling calf 6-8 weeks after spring grazing begins.

Summer Follow Up

Deworm with SAFE-GUARD feed formulations during summer grazing. In warm weather regions, this deworming 6-8 weeks after the spring treatment is important due to high parasite populations and transmission.

Fall Finish

Finish the year by deworming at the end of grazing season or after the first killing frost if you are leaving cattle on pasture year-round.

For Stocker Operations

Spring and Summer

Deworm cattle at turnout or at the beginning of extended grass growth. Follow with a second treatment three to four weeks later. Finish with a third treatment three to four weeks after.

Winter

A deworming treatment at turnout can help provide control for the winter grazing season. A follow-up treatment three to four weeks later is recommended if there was a possibility of pasture containment at turnout.

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.
DOSAGE CALCULATOR

Add pounds, add SAFE-GUARD

Strategic deworming with the SAFE-GUARD Program unlocks performance advantages for cows, calves and stocker animals.

Stockers

For stocker cattle, strategic deworming with SAFE-GUARD added 36.8 lbs. of weight gain.4

Calves

Studies indicate an added 28.9 lbs. to weaning weights on calves strategically dewormed with SAFE-GUARD.5

Reproduction

Strategic deworming with SAFE-GUARD improved conception rates by an average of 10%.6

There’s clean, then there’s SAFE-GUARD clean

All SAFE-GUARD products surpass the 90% parasite reduction threshold7 required for successful deworming. Unlike injectable and pour-on competitors, it’s easy to see SAFE-GUARD is the most effective option.1

Proving success with FECRT testing

No matter your cattle deworming schedule, a fecal egg count reduction test (FECRT) helps measure how well your program is working. In this video, you’ll see a step-by-step guide to conducting an accurate FECRT, learn why it matters and understand what your results reveal.
