  1. The effect of condensed tannins on goats’ body weight

    Dludla, Sicelo Phumlani2010

    Tannins are one of the most common plant secondary compounds. Amongst the tannins are condensed tannins (CT), which occur nearly in every plant species browsed by goats. Condensed tannins have a potential to bind proteins, reduce the feed intake and consequently reduce the body weight gain of …

  2. Carbon based secondary metabolites in African savanna woody species in relation to anti-herbivore defense

    Hattas, DawoodDepartment of Biological Sciences2014

    … woody species have been inferred from foliar condensed tannin and total phenolic concentrations. However these measures are controversial since condensed tannin chemical heterogeneity compromises its simple quantification and total phenolics, which is a measure of general foliar phenolics, …

  5. Quantifying Greenhouse Gas Emissions and Ammonia Volatilization from Soil Amended with Excreta from Ruminants Fed Alternative Forage-based Diets

    Park, Samuel2022

    <p>Forage-based ruminant diets supplemented with condensed tannins or polyphenolic-containing legumes may alter nitrogen (N) metabolism in the animal and reduce gas emissions from soil receiving excreta. The objective of the study was to determine if soil receiving urine or manure from sheep fed …

Relative lack of physical defences appears to encourage giraffes to exploit A. haematoxylon, which has shorter, weaker thorns. Without management intervention, A. haematoxylon could suffer selective mortality through the …

  10. Tannin geochemistry of natural systems: method development and application

    Hernes, Peter J1999

    Polyphenolic tannin comprises a significant proportion of the leaves, needles, and barks of vascular plant tissues---all major contributors to terrigenous organic matter cycling in aquatic systems. However, virtually nothing is known at the molecular level about tannin diagenesis despite the …
