Safe-Guard Food Truck Q&A

The FAQs on feed

Below are some of the most common questions about using SAFE-GUARD feed.

What types of feed are there?

SAFE-GUARD offers a variety of feed formulations including blocks, pellets, cubes and more. Choose the one that fits your operation and management style.

Are feed formulations effective?

Yes. SAFE-GUARD feed formulations deliver the same 98.7% efficacy rate² as the other SAFE- GUARD deworming products, without the need to treat them chute-side.

How do I know how much to give?

Dosage depends on which SAFE-GUARD product you are using. Use our online calculator to determine the right amount based on your herd size.

Typical Dosing

0.5% Pellets: 1lb. per 1,000 lbs. of cattle

Medicated 1.96% Flake Meal: 1/4lb. Per 1,000 lbs. of cattle (1 25 lb. pail treats 98,000 lbs.)

20% Protein Block and ENPROAL^® Molasses Block: One block treats 8,000 lbs. of cattle

How do I know if cattle are getting enough?

The cumulative dose effect of fenbendazole ensures cattle build up a lethal dose over a few feedings. Free-choice options use salt as a limiter to help ensure dominant animals step aside after their dose so the rest of the herd can get theirs.

A comprehensive set of 12 studies have demonstrated that SAFE-GUARD blocks, cubes, pellets and free-choice mineral are effective at keeping cattle clean:

• 12 studies show higher than 91% efficacy for Safe-Guard feed formulations^3-14

• 6 studies show an average extra gain of 40 lbs. in stocker cattle^15-20

• 4 studies show an average weaning weight increase of 31 lbs^{16, 21-23}

• 4 studies show a 16% increase in average daily gain^{4, 18, 19, 24}

Where can I buy SAFE-GUARD feed?

Check with your local feed or farm supply store that carries Merck Animal Health products. Many retailers keep SAFE-GUARD feed in stock or can order them at your request.

Clean up your herd and your pastures with the proven deworming performance of SAFE-

GUARD feed formulations.
