Methods of application of ectoparasiticides to cattle and sheep are by pour-ons, backpack sprayers, spray-races and diptanks.
A ready to use product is applied along the dorsal midline from the neck to the base of the tail.
Before applying pour-on to sheep the fleece must be parted so the product can be appled directly to the skin. The product is applied along the dorsal midline of the sheep.
To ensure that the entire body surface of sheep, including the limbs, is covered product also needs to be applied to the areas at the top of the limbs.
Spray-races and diptanks are commonly used to treat large numbers of animals.
