ONOBRIX

Condensed tannins (TC): act by reducing the risk of bloat (legume glut), protect rumen protein (increased bypass protein) and can reduce gastro-intestinal parasites in ruminants in some cases. This makes the sainfoin very interesting for ruminants (sheep, dairy and beef cows).
Palatability: high; Animals consume sainfoin well when it is in the vegetative state or in good quality hay.

Onobrychis viciifolia

ONOBRIX, also known as sainfoin, is a perennial forage legume valued for its high protein quality, its beneficial condensed tannins (antibloat and protein protection) and its good adaptation to limestone soils and dry/Mediterranean climates. It is used as grazing, hay, silage and in permanent mixtures with grasses.
