→Dipping
The dipping of sheep is a requisite to control ectoparasites in the sheep population. It is though quite a tricky process to get right and a failure at any one of the points could mean that the sheep aren't covered against parasites or that resistance may build up within the parasite population. On the other hand if the concentration of the dip is too high there is significant danger of toxicity to both the sheep and the handler.

A dip should comprise of:
* A holding pen, so that the sheep aren't stressed before the dip.
* A race so that animals can be lead single file into the dip tank.
* The dip tank should have a ledge so that the sheep must jump in and swim to the far end to aid in coverage of the ectoparisiticide. For sheep scan control it is important the every animal has their head submerged.
* A final draining pen, where the sheep can let the excess ectoparisticide drain off back into the tank prior to turn out.
