Journal ArticleDOI
Hydrolysis of phytate and formation of inositol phosphate isomers without or with supplemented phytases in different segments of the digestive tract of broilers.
TL;DR: The hydrolytic cleavage of the first phosphate group is not the only limiting step in phytate degradation in broilers and their gut microbiota to hydrolyse InsP6 in low-P diets.
Journal ArticleDOI
Interactions between supplemented mineral phosphorus and phytase on phytate hydrolysis and inositol phosphates in the small intestine of broilers
Ellen Zeller,Margit Schollenberger,M. Witzig,Yauheni Shastak,Imke Kühn,Ludwig E. Hoelzle,Markus Rodehutscord +6 more
TL;DR: Differences in the concentrations of lower InsPs indicated that the initial step of InsP6 hydrolysis is not the only catabolic step that is influenced by MCP or phytase levels, and effects of added MCP on phyt enzyme efficacy depend on the dose of supplemented phytases.
Journal ArticleDOI
Effects of the composition of the basal diet on the evaluation of mineral phosphorus sources and interactions with phytate hydrolysis in broilers
TL;DR: The objectives of this study were to determine the availability of P from mineral phosphate sources by using different basal diets and measurement of P retention and prececal (pc) P digestibility as well as pc myo-inositol phosphate (InsP) degradation in broilers.
Journal ArticleDOI
Spatial Variation of the Gut Microbiota in Broiler Chickens as Affected by Dietary Available Phosphorus and Assessed by T-RFLP Analysis and 454 Pyrosequencing

TL;DR: In this paper, terminal restriction fragment length polymorphism (T-RFLP) and 454-pyrosequencing were used to determine the microorganisms present in the different sections of the chicken gastrointestinal tract (GIT) (crop, jejunum, ileum and caeca).
Journal ArticleDOI
Modulation of small intestinal phosphate transporter by dietary supplements of mineral phosphorus and phytase in broilers
TL;DR: In this article, the effect of supplemented mineral P with or without phytase on protein expression of two sodium-dependent Pi transporters and a calcium channel was studied in the small intestine of broilers.
