Effect of Alcohol Treatments on Soybean Meal Utilization by Ruminants

Effects of alcohol-water treatments on the nutritional value of soybean meal (SBM) for ruminants was evaluated. Ethanol, propanol and isopropanol were examind at 10, 20, 30 ... 90, 100% (v/v) concentrations. Soybean meal was soaked in an excess of the alcohol-water mixture at 22(DEGREES)C and, after 30 minutes, excess liquid was drained off and the SBM air dried. Concentration of the three alcohols tested resulted in a positive quadratic effect on protein solubility, in situ rate of nitrogen (N) disappearance, and in vitro ammonia release from both soluble and insoluble SBM proteins. In all studies, the effect was largest for the 40% (v/v) propanol treatment. Among alcohols, isopropanol showed the least effect followed by ethanol.
