1,3-1,4-beta-Glucanase · Endo-1,3(4)-beta-Glucanase

Mechanism

Beta-Glucanasen (endo-1,3(4)- bzw. 1,4-beta-Glucanase) hydrolysieren Beta-Glucane der Getreide-Zellwaende (vor allem Gerste und Hafer) und senken die Viskositaet des Darminhalts. In Gefluegel und Schwein sind sie als zootechnische Zusatzstoffe etabliert und EFSA-bewertet (z.B. Endofeed DC, EFSA Journal 2013;11(4):3322; RONOZYME VP, EFSA-Gutachten pub 7703). Beim Pferd fehlen belastbare Wirksamkeitsdaten; das grosse, mikrobiell besiedelte Colon baut Beta-Glucane ohnehin fermentativ ab, sodass ein Vorteil praecaecaler Enzymzugabe fraglich ist. In equinen Versuchen mit fibrolytischen Enzymen (teils beta-glucanasehaltig) waren die Effekte auf die Verdaulichkeit uneinheitlich (vgl. Robinson et al. 2007, J Equine Vet Sci 27(12):535-538). Evidenz beim Pferd: emerging.

Cautions

· Keine belastbaren Pferdedaten
· Kein Ersatz fuer eine bedarfsgerechte, rauhfutterbasierte Ration
· Zusatzstoff-Deklaration (VO 1831/2003) beachten

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.
