With LONGRANGE® (eprinomectin), you can see the results of season-long parasite control.

Conventional dewormers last only 14 to 42 days. That’s not long enough to protect cattle the whole season. As soon as those dewormers wear off, parasites are waiting to reinfect cattle. Only LONGRANGE delivers up to 150 days of parasite control in a single treatment.1,21 - Dependent upon parasite species, as referenced in FOI summary and LONGRANGE product label.2 - LONGRANGE product label. And season-long parasite control can have a big impact on your bottom line.

“The biggest thing about LONGRANGE that we have been impressed with and the main reason we are using it is we can use parasite control on these cows one time in the late spring and the parasite control seemed to last all throughout the entire season, and we didn’t have to bring those cows back in and handle them again and we noticed increased weight gain.”
