Faba bean hulls (var. Nadwiślański) contain approximately, %: CP 14.1, CF 39.6, NDF 54.3, ADF 53.0 and 6.75 mg kg-1 DM condensed tannins. UFL and UFU level was 0.71 vs 0.62; PDIN and PDIE 91g vs 100g kg-1 DM, respectively. The effective ruminal degradability (ERD) of DM, OM, CP and NDF amounted to 25, 29, 52 and 7%, respectively. Faba bean hulls fed at the rate of 18.3% DM of the diet decreased crude protein digestibility (P < 0.01) and increased N-retention (3.8 g vs 5.5 g) in growing sheep. Significantly higher glucose level and decreased urea content in blood serum has been found within experimental animals.
