Polyethylene glycol (PEG 4000), Browse Plus (BP), wood ash (WA) and boiling water were evaluated as tannin deactivation methods on tannins in Acacia nilotica fruits. Twenty four Matebele goats of mean body mass, 38.7 ± 3.12 kg, were used in a digestibility and nitrogen balance trial. A completely randomized design was used, and the initial weight was used as a covariate in data analysis. The go...

a phytochemical screening of fifty five iranian plants belonging to 21 families was carried out. a qualitative phytochemical analysis was performed for the presence of alkaloids, tannins, saponins and flavonoids. the medicinal uses of these plants are also reported.

In spite of the numerous-available clones and cultivars of date palm, few of them produce non-astringent dates at the khalal stage. The astringent fruit must convert to the rutab stage to be edible as fresh dates which means the conversion of soluble tannins to the insoluble form. Applications of the ethylenereleasing compound, namely, Ethrel, even at very high concentrations failed to induce r...

The effects of polysaccharides and tannins present in the hulls of field beans (Vicia faba L.) on the digestion of amino acids, starch and lipid were studied in poultry. A control diet without hulls and the same diet substituted with 400 g hulls/kg diet from three different varieties of beans were fed to 3-week-old chicks for 4 d. Digestibility coefficients for amino acids, starch and lipid wer...

Green and black tea by-products, obtained from ready-made tea industry, were ensiled at 10°C, 20°C, and 30°C. Green tea by-product silage (GTS) and black tea by-product silage (BTS) were opened at 5, 10, 45 days after ensiling. Fermentation characteristics and nutrient composition, including tannins, were monitored and the silages on day 45 were subjected to in vitro ruminal fermentation to ass...

Tannins may bind to alkaloids in endophyte-infected (E+) tall fescue and attenuate fescue toxicosis. To test this hypothesis, thirty-two 4-mo-old lambs were randomly assigned to 4 treatments (8 lambs/treatment) in a 2 by 2 factorial design that included a basal diet of tall fescue hay [E+ or endophyte-free (E-)] supplemented with (TS) or without (CS) bioactive Quebracho tannins. The concentrati...
