Extract

Various ethanol solutions have been used to alter ruminal degradation of soya-bean meal (SBM) protein, thus increasing its post-ruminal availability. The best ethanol solutions for this purpose in wide range of ethanol concentration were reported to be 600 and 700 ml/l by Van der Aar et al. (1984), and Lynch et al. (1987), respectively. However in the literature, there is no degradability data concerning comparison of narrow range of ethanol solutions. Therefore our objective was to compare crude protein (CP) and true protein degradation characteristic of 500, 600 and 700 ml/l ethanol treated SBM.
