Condensed tannins and the nutritive value of herbage
Many plant species contain condensed tannins (CT), but lotus is one of the few herbages of agricultural importance to contain CT. Lotus has a high nutritive value (NV) despite a moderate protein content and nitrogen digestibility, and this can be explained by the activity of CT during digestion. CT binds plant proteins in the rumen, reducing their solubility and degradation by rumen bacteria. C...
متن کاملThe implications of condensed tannins on the nutritive value of temperate forages fed to ruminants.
New methodology for measuring forage condensed tannin (CT) content is described and the effects of CT upon forage feeding and nutritive value for ruminant animals are reviewed. CT react with forage proteins in a pH-reversible manner, with reactivity determined by the concentration, structure and molecular mass of the CT. Increasing concentrations of CT in Lotus corniculatus and Lotus pedunculat...

متن کاملTemperature and Carbon Dioxide Effects on Nutritive Value of Rhizoma Peanut Herbage
Florigraze RP is a warm-season perennial legume used for pasture (Williams et al., 1991) or as conserved Studies assessing the impact of climate change have focused on forage (Prine et al., 1981). Capable of supporting daily plant production, but forage nutritive value, especially of legumes, has often been overlooked. The objective of this study was to deterweight gains of 1 kg in beef cattle ...
متن کاملHerbage mass, nutritive value and canopy spectral reflectance of bermudagrass pastures
Timely and accurate detection of above-ground herbage mass and the nutritive value of pastures can help the more efficient adjustment of stocking rate and determine the timing of protein supplements to be fed to livestock grazing these pastures. The objectives of this study were to determine seasonal variation in herbage mass, neutral-detergent fibre (NDF), aciddetergent fibre (ADF) and crude p...
