powerful all-natural fly control package

Your Herd's Built-In Bodyguard

DefenderPAC started out as a simple, all-natural fly control solution — but it didn't stop there. It still sends out a scent through your cattle's sweat, breath, and saliva that flies, ticks, and lice hate (so your herd grazes more and swats less).

But DefenderPAC does a whole lot more than just fighting insects. Extra diatomaceous earth helps cut down internal parasites, so more feed goes toward milk production and body condition, not worms. Built-in antioxidants clean up free radicals that wear on the system, freeing up energy for growth. And better blood flow means cattle handle summer heat better, with nutrients getting delivered right where they're needed.

It also boosts the rest of your Riomax program.

Nutrizorb (our digestion package) unlocks nutrients, DefenderPAC helps deliver them. Esqort (our mineral package) gets minerals into the bloodstream, DefenderPAC helps them reach the organs and extremities. Together, it all adds up to a stronger herd and a better bottom line.
