Parasites can have many bad impacts on animals, including increased death, lower fertility, reduction in live weight gains and in sheep, the wool production can be reproduced. Drenching is one method of making sure that sheep do not become infected with parasites, and it is important for both animal welfare and farm production.

When drenching sheep it is important to make sure that the metal tube goes behind the teeth of the sheep before releasing the liquid into the mouth of the sheep, and doing this will ensure that the sheep gets a full dose.
