Variability in tannin content, chemistry and activity in a diverse group of tannin containing sorghum cultivars.
BACKGROUND Tannins are large polyphenolic polymers and are known to bind proteins, limiting their digestibility, but are also excellent antioxidants. Numerous studies investigating the functional properties of sorghum tannin have been conducted by comparing grain samples from different sorghum lines without considering the other intrinsic characteristics of the grain. The purpose of this study ...
متن کاملDietary crude protein and tannin impact dairy manure chemistry and ammonia emissions from incubated soils.
Excess crude protein (CP) in dairy cow diets is excreted mostly as urea nitrogen (N), which increases ammonia (NH) emissions from dairy farms and heightens human health and environmental concerns. Feeding less CP and more tannin to dairy cows may enhance feed N use and milk production, abate NH emissions, and conserve the fertilizer N value of manure. Lab-scale ventilated chambers were used to ...
متن کاملOrigin of Oak - Bark Tannin
DRUGS AND UPTAKE OF 32p BY ERYTHROCYTES 533' 5. Sodium salicylate and sodium thiopentone depressed the 32p uptake of 2:3-diphosphoglycerate and adenosine triphosphate to a greater extent than they depressed the 32P exchange of inorganic phosphate and hexose monophosphate. These agents do not depress 32p uptake by inhibiting triose phosphate dehydrogenase, for neither drug had any effect on glyc...

متن کاملInoculation of tannin-degrading bacteria into novel hosts increases performance on tannin-rich diets.
It has been hypothesized that herbivores host tannin-degrading bacteria (TDB) to overcome the toxic challenges posed by plant tannins. While TDB have been isolated from the guts of numerous mammals, their functional significance to their hosts has never been explicitly tested. We introduced TDB into lab rats, which do not host TDB, and measured host performance on tannin-rich diets. We first is...
