The purpose of this trial was to determine the correlation between forage composition, especially nitrogen (N)) fraction cell-wall, and its digestibility of total N fraction. Eleven herbages with different chemical composition were determine the in vivo digestibility using five sheep in total collection technique. From all the herbages examined, the average of apparent digestibility of the protein was 70.4 percent with coefficient of variability (CV) of 17.5 percent. The correlation between apparent digestibility of protein with total N (r = -8.828; n = 1) with NDIN (r = -0.758; n = 9) and with ADIN (r = 0.688; n = 9) were tight. This trial stated that cell wall-N in the feces, as an indication of undigested-N, can be used to estimate total true digestibility coefficient feed protein. The coefficient value was 89.1 percent (CV = 6.3), but not correlated with the proportion of ADIN/Nr (r = -0.039; n = 9) and NDIN/Nr (r = -0.275; n = 9).
