Different approaches to evaluate tannin content and structure of selected plant extracts - review and new aspects

open access: yesJournal of Applied Botany and Food Quality, 2013
Tannins occur in many field herbs and legumes, providing an immense variability in structure and molecular weight. This leads to complications when measuring tannin content; comparability of different methods is problematic.

Effects of Hydrolysable Tannin with or without Condensed Tannin on Alfalfa Silage Fermentation Characteristics and In Vitro Ruminal Methane Production, Fermentation Patterns, and Microbiota

open access: yesAnimals, 2021
This study was conducted to evaluate the potential of hydrolysable tannin (chestnut tannin, CHT) without or with condensed tannin (quebracho tannin, QT) for modulating alfalfa silage fermentation characteristics and in vitro ruminal methane (CH4 ...

Effect of dietary quebracho tannin extract on milk fatty acid composition in cows [PDF]

open access: yesJournal of Dairy Science, 2017
The aim of this study was to examine the capacity of quebracho tannin extract (QTE) to modulate the fatty acid (FA) profile in the milk fat of cows. Fifty Holstein cows yielding 33.2 ± 8.2 kg/d of milk were divided into 2 groups. The cows were fed a basal diet with a forage-concentrate ratio of 66:34 on a dry matter (DM) basis.
