Silvafeed® Tannins Role in Rumen Microbiota Modulation
Published:March 2, 2017
Summary
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 imp...
Hi Claudio, if the experiment was continued over a longer duration do you think the bug populations would revert and adapt to this type of additive?

Before this study we use tannins as astringant in animals suffering from diarrhea and it give agood results witout knowing its effect on rumen but know I know its effect in improving microbial enviroment in rumen its good study
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? It is not expected that there will be adaptation by the rumen microbiota and a return to the initial situation, since the blend of plant extracts that make up the product tested is formed by a large number of different active molecules that make the adaptation is not possible.
