Taiwan’s environmental authorities said Wednesday they are planning to promote potty training for pigs to help curb water and waste pollution.
The Environmental Protection Administration made the pledge following the success of a pig farm in southern Taiwan, where the breeder started to potty-train his 10,000 pigs in late 2009, it said in a statement. To keep his animals from defecating in nearby rivers, the breeder has established special “toilets” smeared with faeces and urine to attract the pigs, it said. This reduced the amount of wastewater by up to 80 per cent. As well as making the farm cleaner and less smelly, it also helped reduce illness among the pigs and boosted their fertility by 20 per cent, it added.
Taiwan has about six million pigs, most of them raised on farms in the centre and the south of the island. Waste from livestock farms is among the main complaints about water pollution received by the administration.
