LongRange®
Grazing season protection in a single dose.
The first and only extended release injectable dewormer
The diminishing effectiveness of traditional cattle dewormers over time, coupled with the tendency for larval levels to peak later in the grazing season, often requires multiple treatments during the season to ensure your herd's health. Enter LongRange® (eprinomectin), a game-changer in the field of parasite management.
Providing protection through the grazing season
As the first injectable, extended release dewormer, LongRange® provides unparalleled protection throughout the grazing season. With just one convenient dose, it delivers up to 150 days of parasite control, revolutionizing the way we protect our cattle from parasites.
LongRange® also delivers average daily gains that outperform other dewormers. In an independent study conducted at a commercial grazing operation in Western Canada, yearling cattle treated with LongRange® gained 23 pounds more than yearling cattle treated with a pour-on ivermectin when used prior to shipment to pasture.1
If you are committed to peak performance, there is only one choice for your dewormer and that's LongRange®.
Broad spectrum protection and flexibility
LongRange® can be administered to a broad range of classes of cattle:
- Yearling grass cattle
- Bulls*
- Replacement heifers
- First calf heifers
- Calves 6 weeks of age and older
- In some cases it may be advisable to treat the cows
*LongRange® is safe to use in breeding bulls.2 Even at 3 times the label dose, no adverse effects on scrotal circumference, libido, semen quality, or sperm characteristics were seen.
LongRange® provides broad spectrum coverage for both internal and external parasites.
Two peaks of effectiveness from Theraphase® formulation
Theraphase® technology, unique to LongRange®, consists of a polymer that, upon injection into the subcutaneous tissue, forms a gel that controls the release of active drug from the site. We see an initial peak, followed by slow-release, and then a second peak around day 100 after the gel breaks down.
This technology allows a single treatment to work for the grazing season and reduces parasite reinfection.
Depending on the parasite species, LongRange® delivers up to 150 days of parasite control in a single treatment. That’s something conventional dewormers just cannot match.2
