Reisprotein

Oryza sativa · Rice Protein · Reisproteinkonzentrat

Mechanism

Reisprotein gilt als hypoallergen und gut verdaulich, ist als Cerealienprotein aber typischerweise arm an Lysin (sowie Threonin/Tryptophan) - der beim Pferd erst-limitierenden Aminosäure (NRC 2007; Graham et al. 1994, PMID 8157522). Vergleichende Aminosäurenanalysen (Kalman 2014, Foods 3(3):394-402, doi:10.3390/foods3030394) und DIAAS-Reviews (Herreman et al. 2020, doi:10.1002/fsn3.1809) belegen ein hohes BCAA-, aber niedriges Lysinniveau. Als alleinige Eiweißquelle deckt es daher den Lysinbedarf schlecht; sinnvoll eher bei Verträglichkeitsproblemen mit anderen Proteinen, dann kombiniert mit Lysin/Methionin. Kontrollierte equine Fütterungsdaten fehlen.

Cautions

· Lysinarm -> deckt die beim Pferd limitierende Aminosäure schlecht ab; ggf. mit Lysin/Methionin kombinieren
· Deklaration/Herkunft prüfen (mögliche Schwermetallbelastung, z. B. Arsen in Reisprodukten)
· Doppelversorgung vermeiden

How the Equiterna Score is built

The Equiterna Score combines three dimensions into a value of 0-100: science (40%), practical experience (30%) and safety (30%). It is transparently derived from evidence level, attributed sources (PubMed/journals), legal classification and cautions. The FEI doping status is shown separately as a competition-law note and does not enter the score. Commissions and vendor relationships have no influence on the score. In addition, the editorial safety rating caps the result: it limits the safety dimension and the overall tier (orange: at most solid). For entries rated red, no score is calculated at all. The rating never raises anything — a green rating does not lift a calculated value.

An editorial assessment of the evidence and safety situation — not a healing claim and not an individual recommendation. It does not replace veterinary advice.

DosageKein fixer Bedarf; je nach Rationslücke ca. 50-200 g/Tier/Tag (500-600 kg); wegen Lysinarmut nicht als alleinige Eiweißquelle.
