You need parasite treatment and control that works. And EPRINEX® delivers. It controls 39 species and stages of internal and external parasites with up to 99% efficacy and no milk withholding.1

  • Multiple studies show that eliminating low (subclinical) parasite burdens produced a consistent increase in milk production.2,3
  • In a study including 28 herds and 954 cows, cattle treated with EPRINEX at calving showed a consistent increase in daily milk production of 2.07 lbs. per day in the first 6 months of lactation, compared to the placebo group (P<0.002).4
  • The only endectocide labeled for control of both Chorioptic (tailhead) mange and Sarcoptic mange in lactating dairy cows.
  • In a study, first-calf dairy heifers treated with EPRINEX required 12.9 fewer days (P<0.05) to conception. A 58% pregnancy rate was achieved, which was 19.9% higher than the control group.5
  • EPRINEX provides added convenience and is safe for all ages, including calves, heifers and dry and lactating cows. And, it requires no milk or meat withdrawal.

We love to watch it work.
