The in situ procedure was used to evaluate the disappearance of dry matter (DM) and crude protein (CP) of four sorghum genotypes with (CMS XS 210 and BR 701) or without (CMS XS 214 and BR 007) tannin in a completely randomized block design experiment with three replicates (animals), in a split plot arrangement. The four genotypes were allotted to the plots and the time of disappearance to the split plot. The DM of CMS XS210 was less degraded when compared to the others and sorghums with tannin showed lower CP degradability when compared to the sorghums without tannin.
