Pope, L.L., K.J. Bruce, L.K. Karr-Lilienthal, C.M. Parsons, and G.C. Fahey, Jr. 2004. Effects of altering bed depth in the desolventizer/toaster used in soybean meal preparation on nutrient digestibility by ileally cannulated pigs and cecectomized roosters. J. Anim. Sci. 82 (Suppl. 1):174 (Abstr.) Link to abstract (.pdf)

Take-home message:

• Increasing the bed depth increases the degree of heating.
• There were no differences in total essential amino acid digestibilities.
• The highest total nonessential amino acid and total amino acid digestibilities were noted when pigs were fed soybean meal processed with the strongest heat treatments of those tested.
