Estimation of rumen degradability of Soy Pass (SP) in comparison with soybean meal (SBM) and 3 concentrate mixtures (KFA, KFB and KFC) by using Nylon Bag (in situ) Technique was conducted with 3 fistulated Holstein Friesian cows. Dry matter (DM) degradation of all tested diets at 2, 4 and 48 h of incubation times was not significant difference (p0.05), but at 8, 16 and 24 h. of incubation times DM degradation of Soy Pass was significant lower (p0.05) than other tested diets. By protein degradation of SP followed the same trend at 16 and 24 h of incubation times DM degradation of Soy Pass was significant lower (p0.05) than other tested diets. By protein degradation of SP followed the same trend at 16 and 24 h of incubation times (p0.05). The estimated effective protein degradation rate of SP at the outflow rates from 4 percent per h and over was clearly lower than that of SBM.
