In an attempt to determine optimal processing conditions to maximize amino acid digestion, soybean meals were produced with different toasting conditions. The depth of the meal was varied in the desolventizer-toaster to simulate different toasting conditions. The resulting meals were evaluated using ileal-cannulated pigs and cecectomized rooster assays. Results indicated that varying the depth of the meal in the D-T unit had little effect on digestibilities of nutrients in soybean meal for swine or poultry.Pope, Lynda and co-workers. 2004.
