2007 journal article

What aspect of dietary modification in broilers controls litter water-soluble phosphorus: Dietary phosphorus, phytase, or calcium?

JOURNAL OF ENVIRONMENTAL QUALITY, 36(2), 453–463.

MeSH headings : 6-Phytase / administration & dosage; Animals; Calcium, Dietary / administration & dosage; Chickens; Diet; Female; Male; Manure / analysis; Phosphorus / analysis; Phosphorus, Dietary / administration & dosage

MeSH headings : Animal Feed; Animals; Chickens; Female; Male; Manure / analysis; Phosphorus / analysis; Solubility; Water / analysis
TL;DR: As total P and WSP are indicators of the long and short term impacts manure applications can have on P losses from manured soils, diet modification should be seen as environmentally beneficial. (via Semantic Scholar)
