The objective of this Study was to evaluate the effect of organic fertilizer and cuts on the chemical composition and in vitro digestibility of the air pornunça biomass. The experimental design of randomized blocks in a split plot with four courts, two fertilization, and four replications. The cuts were made in February, June and October 2011 and February 2012. The fertilizer was with cattle and sheep manure, applied in May 2010 and March 2011 in the amount of 20 Mg ha-1. We evaluated the structural components of the shoot, such as leaf blade, petiole, branch and full (leaf blade and petiole more branch) of pornunça. The manure beef and lamb did not influence (P>0.05) the chemical composition of the structural components of the shoot. Differences were noted between the cuts, except for dry matter (DM) of the leaf blade and the full component of ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose (HC). There was a significant (P
