Maturation effect on changes in chemical composition of 4 perennial grasses was investigated. Meadow fescue (Festuca pratensis L.), cv. K-21, perennial ryegrass (Lolium perenne L.) cv. Naki, timothy (Phleum pratense L.) cv. K-15 and tall fescue (Festuca arundinacea Schreb.) cv. K-20 were sown as pure stands. Sampling began on April 26 when all grasses were in vegetative phase and continued in 7-days intervals till June 7 (timothy till June 14). From the youngest phase to phase of ripe seed in tall fescue crude protein decreased from 255.2 g/kg SM to 83.0 g/kg SM followed with crude cellulose increasing. The most mature plants of tall fescue had highest crude cellulose content (479.9 g/kg SM). In average, the highest crude protein content was in tall fescue (124.8 g/kg SM) and the lowest cellulose content was in timothy (268.2 g/kg SM). Tall fescue had the highest minerals content (9.95 g/kg SM).
