Sprinkling and soaking
The weaner unit can be designed with sprinkling and soaking. In Danish units with pigs weighing more than 20 kg, sprinkling must be established. Sprinklers are used to cool down the pigs and to control dunging behavior in the pen. The sprinklers are placed above the dunging area at a distance that ensures the correct spreading in regards to the nozzles. The sprinklers are adapted to the tempera- ture strategy and set at intervals adapted to the behavior of the pigs, so that no competition and fighting occurs. The sprinklers also ensure that the slats are kept clean throughout the growth period.
Soaking promotes the cleaning work in the pens and helps clean the units quickly. Soaking can be connected to the sprinkler string, and the nozzles are then placed dependant on the demand for sprinkling and the size of the pens.
