- Saviotan Feed For a Protein By Pass Activity
Saviotan Feed enhances correct digestion and absorption of amino acids in the intestinal tract because it has the capability to reduce the protein degradation in the rumen. Saviotan® Feed has the biological properties to form a tannin-protein complex Hydrogen bonds] at certain pH conditions 13.5-8.0. These complexes, stable at rumen pH, dissociate when the pH falls below 3.5 (such as in the abomasum where pH is 2.5-3.0]. In the rumen, tannins act as a protein carrier, reducing the protein attack by the ruminal microflora. Due to a lower pH in the abomasum compared to the rumen, a progressive release of proteins occurs from the tannin complex by-pass effect).

- Saviotan Feed for Reduction Of the Methane Emission
Methane produced during anaerobic fermentation in the rumen, represents a feed energy loss and contributes to an increase in the greenhouse effect. Chestnut extract, rich in Hydrolysable Tannins, decreases ruminal methane emission lin vitro triall mainly due to inhibition of the growth of methanogens protozoa responsible of methanogenesis in the rumenl. Filed experience confirms that animals, fed with Chestnut extract, have a lower methane emission.

- Saviotan Feed for its Antioxidant Properties
Saviotan Feed is a polyphenol and exhibits greater antioxidant activities than simple phenolics: the number of hydroxyl groups and the degree of polymerization of tannin are considered to be correlated with their ability to scavenge free radicals. Antioxidant activity has been evaluated in vitro by using Folin-Ciocalteu reagent. The results are expressed as total phenol content, measured as GAE (Gallic Acid Equivalents) which is considered to have an excellent correlation with the in vitro antioxidant activity.

Technical Details & Test Data
- Saviotan Feed for Urea Milk Reduction
Milk Urea Content is lower when using Saviotan Feed; field trial performed on 30 dairy cows demonstrates that dietary supplementation of Saviotan Feed reduces the milk urea content [-7%] confirming the more efficient use of protein nitrogen.

- Saviotan Feed for Reducing Bloat Severity
In vivo studies attested that supplementation of Chestnut Tannin reduces the rate and frequency of frothy bloat, and bloat frequency due to the precipitation of soluble proteins (tannin complex decreases Ruminal Degradable proteins and increases Undegradable Proteins) and through antimicrobial activity of tannins towards gram- positive bacteria.
The study was carried out on twenty-six heifers (286 +/-26 Kgl visually monitored daily for bloat score (0= no bloat; 3- severe bloat]. Chestnut tannin supplementation increased Average Daily Gain and mean bloat score and bloat day were greater for the control diet than for Chestnut tannin supplemented treatment groups.Body weight (Kg)

- Saviotan Feed for Intestinal Microbiota Control
SaviotanFeed interteres with the development of Campylobacter jejuni and Clostridium pertringens. Not all the four bacterial colonies reacted to Saviotan bacteria and parasite in gut because it complexes membrane protein altering the permeability of the cellular membrane. Saviotan Feed antimicrobial activity was tested in vitro on Salmonella typhimurium, Escherichia coli, Feed in the same way: Escherichia coli resulted the least sensitive and Clostridium perfringens the most sensitive.

- Saviotan Feed for Diarrhoea Control
Chestnut tannin controls diarrhea through its antispasmodic effect [it slows the peristaltic movements of the intestinel. In vitro result has been confirmed by in vivo trial: oral administration of Saviotan Feed reduces the duration of neonatal diarrhea. Trial has been pertormed on 24 Italian Friesian calves, both male and female, and the results are reported here following: the duration of the diarrheic episode (DDE) was significantly reduced of 4 days and the Fecal Score was significantly better in the group treated with Saviotan Feed (5g/liter)
