In experiments in Camaguey Province during the wet season (May-June), the chemical composition and digestibility of 3- to 8-weed-old regrowth of P. maximum grown in fertilized soils were investigated. OM, CF and lignin contents generally increased with age while CP and in vitro DM digestibility decreased. Digestibility ranged from 63.9 to 54.6%, was negatively correlated with CF and lignin contents and was positively correlated with CP content. No significant differences were detected in DM, NFE, ash, Ca, P and Mg contents.
