Aging of whole oats or triticale crops changed the chemical composition of whole crop silages. The main effect was an increasing content of starch. Prolonging growth increased lignification of the plants only from heading to milk stage of maturity. The starch content had a greater effect than NDF on in vivo, in situ and in vitro digestibility. In vivo DM digestibility was significantly correlated with rumen DM degradability parameters (A and B) of the in situ method, IVTD 48 h and GP rate constant
