At the Instituto de Zootecnia, Nova Odessa (SP), Brazil, it was carried out an experiment to evaluate 24 cultivars and 36 sugarcane clones as raw material for animal feeding. The experimental design was set in randomized blocks with three replications. The sugarcanes were harvested at 12 and 18 months. Genotypes and age of harvest showed differences for %DM (dry matter); %CP (crude protein; %EE (ether extract); %ACH (ach); %TNC (total non-structural carbohydrates) , %NDF (neutral detergent fiber); %ADF (acid detergent fiber); %CEL (cellulose); %HCEL (hemicellulose) and %LIG (lignin), except for %EE, for harvest ages. Significant differences for %TNC, %NDF, %ADF, %CEL, %HCEL and %LIG) were observed for two ages of harvest.
