High quality forage proteins for tropical goat dairy feeds are often difficult to find and many perennials contain condensed tennins that may not always benefit production the objective of this study was to evaluate milk yield apparent digestibility of nutrients and intake of crossbred dairy goats fed tifton 85 grass replaced by the leguminous shrub flemingia with or without polyethylene glycol to neutralize CT which were present at 105g/kg DM.treatments consisted of six diets containing 0%,12.5% and 25% flemingia with or without PEG.Adding flemingia increased dietary concentrations of CT,lignin, protein and rapidly degradabie polysaccharides the digestibility of nutrients at 12.5% of flemingia inclusion didnot differ from the legume-free diet however,levels of 25%negatively influenceed intake of hemicellulose and dry matter organic matter crude protein neutral detergent fiber and total carbohydrate digestibility,petiole and petiolule indicated the presence of idioblasts with phenolic compounds in trichome, collenchyma and parenchyma cells. we conclude that flemingia leaves can replace tifton 85 grass as a supplement in low quality diets of dairy goats.
