Online published on 31 March, 2014. Abstract The total phenolics, non tannin phenolics and total tannin content of sixteen commonly available forages in Tamil Nadu for feeding ruminants were analyzed. A highly significant (p<0.01) difference was observed between forages and shrubs/tree fodders (foliages). Among forages the highest total phenolics was present in Sorghum vulgare (4.63%) and lowest in Cynodon dactylon (0.72%). In tree fodders, the highest total phenolic was observed in Acacia nilotica (10.96%). In forages, the maximum non-tannin phenolics were recorded in Brachiaria mutica (2.25%) and the minimum in Stylosanthes scabra (0.54%). Among tree fodders, Moringa oleifera had the highest (1.23%) non-tannin phenolics and Albezia lebback had the lowest (0.41%) level. Highest total tannin was present in Sorghum vulgare (3.18%) and lowest in Panicum maximum (0.08%) within forages. Among tree fodders, Acacia nilotica (10.12%) had highest tannin content.
