The objective of this work was to determine the ruminal degradability of dry matter (DM) and crude protein (CP) of maize grain (MG), oat grain (OG), wheat meal (WM) and rice meal (RM). The in situ technique was used with nylon bag, and the 0, 3, 6, 12, 18, 24, 48 and 72 hours intervals of ruminal incubation were evaluated. Four steers were used in a 4 x 4 latin square. The dry matter of the OG presented the highest soluble fraction (36.58%), the highest rate of degradation (12.95% h-1) and the highest effective degradation (ED) (79.28%). The RM presented the lowest potential degradable fraction (29.24%) and the lowest ED of DM (49.16%). The MG presented the highest soluble fraction of CP (56.88%). The OG presented the highest degradation rate of CP (11.05%). The WM presented the highest ED of CP (77.38%) and the RM presented the lowest ED of CP (66.65%).
