The objective of this work was to evaluate the effect of the forage conservation method on the nutritional value of the maniçoba (Manihot epruinosa Pax & Hoffmann). The research was per formed Animal Science Department of UFRPE. It was determined the concentration of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), ash (AS), neutral detergent fiber (NDF), acid detergent fiber (ADF), neutral detergent insoluble protein (NDIP) and acid detergent insoluble protein (ADIP). The pH was determined the silage, and the buffering capacity (BC) in the fresh material. It was used 15 animals. In the fresh maniçoba, the water concentration and the BC were 30.99% and 132.6 meq NaOH/ kgDM, respectively. These parameters promoted satisfactory fermentation and good quality silage, with pH of 4.07. There was no interaction (P>0,05) between conservation form and animal species in relation to intake. The CPI (0.056 and 0.042 kg, hay and silage) and EEI (0,024 and 0.014 kg, hay and silage) were greater in the animals than consumed hay. The intake differences for the other nutrients (OM, NDF, TC and NFC) were not significant. There was no interaction (P>0.05)between conservation method of the maniçoba and animal species for digestibility, as well as TDN, being the values of TDN of 41.14 and 43.88%, respectively for hay and silage.There was no significant difference for digestibility of several nutrients, except for EE, that presented difference between conservation method, with values of 33,26 and 14,82% for hay and silage, respectively.
