FEEDING an enzyme called phytase to pigs and combining aluminum chloride with their manure, reduces phosphorus pollution in pigmeat production run-off water by as much as 70% according to a study by the USA Agricultural Research Service. Adding aluminium chloride alone reduces phosphorus by 53%, whilst phytase reduced it further because it helps pigs digest phosphorous.
