TI  - Effect of heat treatment and subsequent urea supplementation of sunflower meal on 
      the in vitro ruminal degradability of crude protein content and its postruminal 
      digestibility.
PG  - 255-64
AB  - A three-phase laboratory procedure was used for predicting the degradability of 
      the protein of extracted sunflower meal before (SFM) and after heat treatment 
      (HSFM). The rumen fluid degraded 69.1% and 67.1% of the SFM and HSFM protein, 
      respectively. The digestibility values of rumen undegraded protein (UDP) were 
      57.3% (SFM) and 57.0% (HSFM) with pepsin and 17.6% (SFM) and 15.9% (HSFM) with 
      pancreatin. Urea supplementation practically did not alter the rumen 
      degradability of HSFM protein, while the pepsin digestibility of UDP decreased to 
      47.2%. Four fractions (NH3, dissolved amino acids, oligopeptides and proteins) of 
      rumen degradable crude protein (RDP) were also determined in vitro: 81 to 92% of 
      the degraded crude protein was found in the fractions tested. Heat treatment 
      reduced free NH3 content but did not alter the other three fractions. Urea 
      supplementation decreased the quantity of NH3, peptides and proteins as well.
