Cydectin® (moxidectin) Pour-On

The industry's #1 selling pour-on deworming brand contains the active ingredient moxidectin, which controls 33 parasite species and stages while remaining dung beetle and earthworm friendly.1,2,3

Cattle parasites can cause a host of problems in cattle from reductions in milk production, reproductive performance and growth rate to increased disease susceptibility.4 This can occur even with subclinical infection when symptoms may not be noticeable. Researchers have estimated, without dewormers, cow-calf producers would sacrifice more than $165 per head in lost returns.5 Overall, for the entire beef production system, the impact of eliminating dewormers on break-even prices totaled $190 per head.5
