0 (one of) a group of chemicals that are found in plant cells, especially in leaves, bark (= a tree's outer covering), and fruit that is not yet ready to eat
However, condensed tannins can also lower palatability, voluntary feed intake and digestibility.
Secondly, the question of the physiological significance of concentrations of tannins tested in vitro is also relevant.
Apart from their strong affinity for proteins, condensed tannins can form complexes with metal ions and have radical scavenging properties10.
There is a wealth of evidence suggesting that condensed tannins in plants influence the voluntary feed intake, palatability and digestibility of the fodder2,4,5.
Within plants, condensed tannins are concentrated in cell vacuoles12 and usually occur in higher concentrations in leaves and reproductive organs than in stems and roots14.
Goats fed tannin-containing leaves do not exhibit toxic syndromes.
What are their concentrations of condensed tannins and what are the most important drivers of fluctuations in tannin concentrations under field conditions?
Preferences for foods varying in macronutrients and tannins by lambs supplemented with polyethylene glycol.
