BARF Teil 11

Vitamin A (Retinol)

Retinol ist gut für die Sehfunktion, Haut, Knochenwachstum und die Erhaltung der
Schleimhäute.

 

Es ist besonders in Eier, Leber, Hühnerfleisch, Fisch, Möhren, Spinat, Schnittlauch, Kresse, Mangold, Brennnessel, Löwenzahn enthalten. Vitamin A ist als Provitamin (ß-Karotin) in Karotten und grünem Blattgemüse enthalten. Hunde sind in der Lage, bei Bedarf dieses Provitamin in reines Vitamin A umzuwandeln.

 

Ein Mangel an Vitamin A tritt bei ausgewachsenen Hunden eher selten auf. Falls doch, wird die Sehfunktion gestört, da die Bindehaut, wie alle anderen Häute
im Körper, austrocknet. Weitere Symptome sind: erhöhte Anfälligkeit für Infektionen, Hörschwäche, und bei Welpen: Wachstumsstörungen.

 

Ebenso kommt in der Regel ein Überschuss kaum vor. Passiert es doch, so wird das überschüssige Vitamin A ins Blut abgegeben und es kann zu Haarausfall, Hautveränderungen, Übererregbarkeit, Abbau von Knochensubstanz kommen. Bei
erhöhtem Bedarf empfiehlt es sich, pflanzliches Vitamin A (ß-Karotin) zu geben. Gibt es keinen Bedarf, kann dieses Provitamin (ß-Karotin), da es wasserlöslich ist, im Gegensatz zum reinen Vitamin A ausgeschieden werden.
