The experiment was conducted in order to evaluate the pH, chemical composition, fractions which constitute the total carbohydrates (CHT) and energy values of cassava mass silage with wheat meal in PVC silos with capacity for 12 kg, randomly distributed in three replications. The samples had been taken at 0, 6, 18, 25, 45 and 60 days after ensilage. The dry matter (DM), ether extract (EE), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), non-fiber carbohydrates (NFC), lignin contents and pH, CHT fraction and energy were analyzed. There was linear effect (P<0.05) for pH values, that decreased with the ensilage time, and positive quadratic effect (P<0.05) for DM concentration. The CP, EE, NDF, ADF, lignin, CHT texts of PB, EE, FDN, FDA, lignin, CHT, CNF, total fractions of CHT, total digestible nutrients and energy contents were constant (P>0.05) in function of the ensilage time. In func-tion of the results, the cassava silage is showed as alternative source of energy concentrate for ruminants feeding.
