The original ivermectin backline pour-on for cattle at 5 mg/mL. Animals are treated moving through a race rather than head-bailed one at a time, which is the whole appeal — but coverage depends on a dry, reasonably clean coat, so it is not the tool for a wet muster.
It carries the longest withholding in the Ivomec pour-on range at 42 days meat and 42 days ESI, and it is not for lactating dairy cows. If you need a short or nil withholding, use Ivomec LV or Ivomec Eprinex instead.
Supplied in 1L, 2.5L, 5L and 20L.

Safety
Macrocyclic lactone actives (ivermectin, abamectin, moxidectin, eprinomectin) are toxic to dogs, and severely so in herding breeds such as Collies, Border Collies, Australian Shepherds and Kelpies. Keep dogs away from treated animals until the product has dried, store the container out of reach, and dispose of empty packs and used syringes where a dog cannot get at them. Withholding periods and export slaughter intervals apply — read the label before treating any animal destined for sale, and rotate chemical groups between seasons rather than relying on one active, because resistance is the main reason a treatment stops working.
