Published on: 03/14/2017
Author/s : Silvateam

For many years dietary protein binding has been considered the main property of tannins within animal nutrition, but more recent speculations have highlighted many other mechanisms of action for tannins.Antispasmodic effect on gastrointestinal passage, reduction of rumen starch degradation, local immune response modulation and antioxidant effect are some known examples, but perhaps the most import...

Tannins , especially HT has negatively effects on fibrolytic bacteria and followed by reduction of fibre digestion in rumen, but tannins ( CT and also HT) are able to bind proteins , which resulting to escape more them from rumen. They cause to absorb more sulfur containing amino acids, as a result, they increase fiber values like cashmere, wool in fiber- producing animals.

Hi David, how are you?
