Extract

During steam treatment of lignocellulosic materials lignin is depolymerised (Zahedifar, 1996) to lower molecular weight phenolic compounds. Those phenolics may have protein precipitating capacity (PPC) due to bearing some hydroxyl groups on their molecule (Kawamoto et al, 1992) as do some other phenolics like tannins. Protein precipitating capacity of tannins may have a positive effect in ruminants by protecting proteins from microbial degradation in the rumen. The aim of this study was to assess the PPC of the phenolic compounds extracted from steam-treated wheat straw (STWS) and possible use of them to protect protein from rumen microbial degradation.
