Find the right cattle dewormer for your herd.
When it comes to controlling parasites, choosing the right cattle dewormer can help you get the most from your herd. That’s why Merck Animal Health offers a variety of options, available in a variety of formulations.
SAFE-GUARD®
(FENBENDAZOLE)
Goes straight to the gut, killing parasites where they live.
Powered by fenbendazole, SAFE-GUARD (fenbendazole) dewormer features broad-spectrum protection against the most concerning parasites. It’s available in a variety of options, including drench and feed formulations, so you can deworm when and how you want – at the chute, with feed or in the pasture.
Put your cattle dewormer to the test.
After deworming, you should see a 90%+ reduction in fecal egg counts. But how do you know? A Fecal Egg Count Reduction Test, or FECRT, is a diagnostic tool with the ability to tell you just that. This video walks through the step-by-step process of how to conduct an accurate FECRT.
