Palacios, M. F., R.A. Easter, K.T. Soltwedel, C.M. Parsons, M.W. Douglas, T. Hymowitz and J.E. Pettigrew. 2004. Effect of soybean variety and processing on growth performance of young chicks and pigs. J. Anim Sci. 82:1108-1114. Link to full text (.pdf)

Take-home message:

• Removal of lectins and Kunitz trypsin inhibitor from soybean improved growth performance compared to unprocessed conventional soybeans.
• However, these soybeans still need to be heated to achieve same growth performance as soybean meal or extruded soybeans.
