Outline of Final Research Achievements |
The aim of this study was to investigate chemical properties of tannins and their effects on ruminal protein degradation in tropical and temperate legumes for ruminant feeds. Among 16 species of legumes, condensed tannin contents varied from 0.0 to 10.3% on a dry matter base. Although most of legumes showed weak or no suppression of ruminal protein degradation, Lotus corniculatus from temperate legume and Desmodium intortum from tropical legume clearly suppressed protein degradation. The suppressed protein degradation in rumen could be due to lowered protein solubility by tannins in these species.
