What about silvafeed in poultry diet .

Many thanks for your interest. First, the choice of an animal model for monogastrics was made to get some insights on the mechanisms of actions. For poultry we can expect very similar effect, which is also supported by our field trials.

As i am doing mphil in poultry science and i read that its not good for poultry .thanks for your reply

Good luck with this. Also, be careful if you come across old literature - it may not give you a correct overview of tannin benefits. Once you get the right dose and tannin composition, you will see a lot of good things!

I wanted to ask Dr. Desrues, I used the tannin in combination with organic and inorganic acids, in growing pigs, and I found an enhancement of the effects.
Is it just my feeling on the field, or do you have any evidence that this happens, or is it a useless combination?
Thank you for the reply.

Dear Marco, very interesting point there. We have got feedback from farms that support your field experience. From the published reports, it seems that such combination is at least not detrimental; and in some cases can give good results (partly due to the additives or synergistic effects on bacterial populations in the gut, with less pathogenic species and more beneficials ones). But the possible combinations of types of tannins and acidifiers are numerous... and might not all give the same results. So to be continued

I use the tannins topic to ask a question:
I have read that hydrolysed tannins can have an inhibitory effect on the total activity of the blind bacteria, an interesting aspect because this reduction could result in a lower microbial synthesis of cannula and indole, which is responsible for the smell of vermin intestinal tract of whole male pigs.
Do you have any experiences or studies that can confirm this? Where can I find them?
thank you

Hi Marco,

Good to see that you keep track of every possible use of tannins!

Yes there are studies on hydrolysable tannins to reduce boar taint, but to my understanding they mainly look at the effect on hormones and enzymes that influence clearance of skatole.

Thank you sir. Desrues, I am very interested in the use of tannins and the various uses that can be made, even non-food use example quebracho tree tannins, for controlling and productions of compounds that cause manure odors, including hydrogen sulphide.
I've read the studies ARS (USDA) scientists research and I hope the results obtained in vitro can be replicated in breeding.

Do you have any trials comparing the effect on animal performance of 2500 ppm ZnO with your product in post-weaning piglets?

Hi Steffen,

Yes one study, although they compared 3000 ppm ZnO with partial replacement (Silvafeed+half dose ZnO). It gave good results for FCR, BWG and reduction of diarrhea (no visible change for feed intake)

Olivier Desrues Any link to that investigation or just some performance data?

Steffen Hansen
currently unpublished, but I can send by email some performance data (odesrues@silvateam.com)

I will check if we will publish this on Engormix anytime soon

Olivier Desrues Thanks

I was inspired by this research and found interesting benefits as I wrote in a previous post.

Marco Baroni I receive an error when I try to open the link

Marco Baroni

Yes I remember, I just hope you have tried with italian chestnut extract! You can contact me for this of course.

I am waiting for research papers to be published on diahrrea in piglets, so I will keep you update.

I checked the site is this:

Try also to find it on the site:

I do not understand I have no problems finding it.
good work and good luck.
