Evaluation of Phosphorus Characterization in Broiler Ileal Digesta, Manure, and Litter Samples: <sup>31</sup>P‐NMR vs. HPLC

Journal of Environmental Quality, 37(2), 494–500.

By: A. Leytem*, P. Kwanyuen*, P. Plumstead n, R. Maguire* & J. Brake n

MeSH headings : Animals; Chickens; Chromatography, High Pressure Liquid; Gastrointestinal Contents / chemistry; Ileum; Magnetic Resonance Spectroscopy; Manure / analysis; Phosphorus / analysis; Phytic Acid / analysis
TL;DR: The quantification of phytate in all samples was very consistent between the two methods, and suggests that (31)P-NMR is a very reliable method for quantifying P compounds in manure/litter samples. (via Semantic Scholar)

2008 journal article

Interaction of Calcium and Phytate in Broiler Diets. 1. Effects on Apparent Prececal Digestibility and Retention of Phosphorus

Poultry Science, 87(3), 449–458.

By: P. Plumstead n, A. Leytem*, R. Maguire*, J. Spears n, P. Kwanyuen* & J. Brake n

author keywords: broiler; phosphorus; soybean meal; phytate; environment
MeSH headings : Animal Feed; Animal Nutritional Physiological Phenomena; Animals; Calcium, Dietary / administration & dosage; Calcium, Dietary / pharmacology; Chickens / growth & development; Chickens / metabolism; Digestion / drug effects; Dose-Response Relationship, Drug; Female; Ileum / metabolism; Intestinal Absorption / drug effects; Male; Nutritive Value; Phosphorus, Dietary / pharmacokinetics; Phytic Acid / administration & dosage; Phytic Acid / pharmacology; Random Allocation; Soybeans
TL;DR: It is suggested that increased dietary Ca reduced the extent of phytate P hydrolysis and P digestibility and that the optimum Ca:NPP ratio at which P retention was maximized was reduced when diets contained less phytte P. (via Semantic Scholar)

2008 journal article

Interaction of Calcium and Phytate in Broiler Diets. 2. Effects on Total and Soluble Phosphorus Excretion

Poultry Science, 87(3), 459–467.

By: A. Leytem*, P. Plumstead n, R. Maguire*, P. Kwanyuen*, J. Burton* & J. Brake n

author keywords: broiler; soluble phosphorus; excreta; phytate; environment
MeSH headings : Adaptation, Physiological; Animal Feed; Animal Nutritional Physiological Phenomena; Animals; Calcium, Dietary / pharmacology; Chickens / growth & development; Chickens / metabolism; Dose-Response Relationship, Drug; Drug Interactions; Female; Ileum / metabolism; Male; Phosphorus / metabolism; Phosphorus, Dietary / pharmacokinetics; Phytic Acid / pharmacology; Random Allocation; Solubility; Soybeans; Time Factors
TL;DR: The response in WSP to dietary manipulation was important from an environmental perspective because WSP in excreta has been related to potential for off-site P losses following land application. (via Semantic Scholar)

2007 journal article

What Aspect of Dietary Modification in Broilers Controls Litter Water‐Soluble Phosphorus

Journal of Environmental Quality, 36(2), 453–463.

By: A. Leytem*, P. Plumstead n, R. Maguire*, P. Kwanyuen* & J. Brake n

MeSH headings : 6-Phytase / administration & dosage; Animals; Calcium, Dietary / administration & dosage; Chickens; Diet; Female; Male; Manure / analysis; Phosphorus / analysis; Phosphorus, Dietary / administration & dosage
TL;DR: While feeding reduced AvP diets with phytase decreased litter total P, the ratio of Ca/AvP in the diet was primarily responsible for effects on WSP, important from an environmental perspective as the amount of WSP in litter could be related to potential for off-site P losses following land application of litter.
