Effects of ethanol, heat, and lipid treatment of soybean meal on nitrogen utilization by ruminants
Ruminant nitrogen utilization of soybean meal treated with (1) 70% ethanol at 23 or 78/sup 0/C, (2) 10% coconut oil or tallow, or (3) a combination of 70% ethanol at 78/sup 0/C and coconut oil or tallow was evaluated. Nitrogen solubility was lowest for soybean meal treated with ethanol at 78/sup 0/C, ethanol plus coconut oil and ethanol plus tallow. In situ nitrogen disappearance was lowest for soybean meal treated with ethanol at 78/sup 0/C, ethanol plus coconut oil, and ethanol plus tallow. Rates of nitrogen disappearance between 3 and 12 h were lowest for soybean meal treated with ethanol at 78/sup 0/C, ethanol plus coconut oil, and ethanol plus tallow. Nitrogen retained by lambs was greater for lambs fed soybean meal treated with ethanol at 78/sup 0/C than for those fed untreated soybean meal. Ruminal ammonia 4 h post feeding was lowest for lambs fed soybean meal treated with ethanol at 78/sup 0/C, ethanol plus coconut oil, and coconut oil. These data indicate that the 78/sup 0/C ethanol treatment improved nitrogen utilization.
