Internal parasites may be out of sight, but Dr. Deanna Hardee with Merck Animal Health says they’re never out of mind when it comes to livestock performance. Hardee notes that parasites don’t just steal nutrients — they disrupt gut health, weaken immunity, and quietly take dollars off the bottom line.
She says strategic deworming, good management, and the right product choices are key to keeping herds healthy and productive. Protect the gut, protect the gains.
