Abstract This report describes the results of the research into the orthophosphate content in (separated) pig manure and faeces. Manure from several different animal categories was collected and separated with a screw press or a centrifuge, and samples were collected of the manure and fractions and analyzed on the content of available orthophosphate and total phosphate. Furthermore, the orthophosphate was extracted from the liquid fractions of the centrifuge with calcium hydroxide. The orthophosphate contents were low with the exception of the faeces of piglets and finisher pigs fed dry feed which had a content of around 2459 mg/kg.
