Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

open access: yes, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

DETERMINING THE TANNIN CONTENT IN PISANG AMBON (Musa × paradisiaca L.) WITH THE POTENTIAL AS ANTHELMINTIC

open access: yesJurnal Kimia Riset, 2022
Tannins result from plants' secondary metabolism, closely associated with plant defense mechanisms against insects. Condensed tannins can disrupt the life cycle of parasitic nematodes starting from eggs, adult worms, and larvae.
