This study was carried out to determine whole seed soybean L17 (WSB) dry matter degradation characteristics by using nylon bags. The rumen degradability of WSB dry matter at ruminal outflow rate of 0.02/h, 0.05/h and 0.08/h were 72.90, 54.56 and 45.36 respectively. Dry matter degradability of WSB at 0, 2, 4, 8, 16, 24 and 48 h incubation were 21.79, 22.75, 27.17, 34.84, 53.04, 79.56 and 83.96 percent.
