The natural behaviour of pigs is that they choose their lying area first and thereafter the defecating area. By concentrating faeces and urine depositions to a small area both fractions can be removed separately.
The toilets also offer pig farmers possibilities to reduce the environmental nuisance. Separation reduces the formation of volatile ammonia. Quick removal of manure reduces the methane and odour emissions.
Application at pig farms
After we tested several pig toilet designs at our Swine Innovation Centre, some commercial pig farms have installed them, based on the gained knowledge.
Better welfare and health
Constructing pig toilets considerably contributes to the mandatory reduction of undesirable emissions from pig farms and contributes to animal (and human) welfare and health. Because of their apparent advantages, pig toilets are expected to be widely used in the future.
