Three multiparous, dry, fistulated Holstein cows were used to evaluate degradability of complete diets: sorghum silage with concentrate of ground corn or triticale and soybean meal or yeast. Effective degradability of dry matter (EDDM), crude protein (EDCP) and neutral detergent fiber (EDNDF) was evaluated. In relation to dry matter, triticale and yeast diets presented a higher (p < 0.05) value for soluble fraction and EDDM for different passage rates. The soluble fraction of crude protein was higher (p < 0.05) for ground corn and yeast diets and triticale and soybean meal diets. The EDCP was higher (p < 0.05) for triticale and yeast diets in passage rates of 5%/h and 8%/h. In relation to neutral detergent fiber, foods had no influence (p < 0.05) on complete diets as for the parameters analyzed.
