Livestock Industry Facilities and Environment: Swine Cooling Methods—Drip Cooling

Drip cooling systems are used to drip water on the shoulder of sows or boars in a crated situation. This allows evaporation of the water which removes heat from the neck where a large blood supply is present. It is best used for systems where the animal is confined below the drip nozzle. In farrowing crate usage it has been shown to reduce sow respiration rate, increase feed consumption and improve litter weights.https://lib.dr.iastate.edu/extension_ag_pubs/1164/thumbnail.jp
