Protein and energy evaluation of soybean meals processed from genetically modified high-protein soybeans

HM Edwards 3rd, MW Douglas, CM Parsons, and DH Baker

Department of Animal Sciences, University of Illinois at Urbana-Champaign, 61801, USA.

A conventional and two genetically modified soybean samples were processed to dehulled soybean meal (SBM) at a pilot plant and were compared with SBM from a commercial processing plant. Crude protein levels (%) of the experimental SBM samples were M700, 52.5; M702, 53.4; and M703, 62.7. The commercial SBM sample (UI) contained 47.5% protein. Amino acid, gross energy, lipid, and fiber analyses were carried out, and true metabolizable energy and true amino acid digestibility were determined with adult cecectomized cockerels. Digestible Lys, Met, Cys, Thr, and Val, and also TMEn, were higher (P < 0.05) and NDF, fat, and phospholipids were lower in M703 than in the other SBM samples. The results of this study indicate that M703 has considerable advantages over conventional SBM as a feed ingredient for broiler chickens.
