High efficiency soybean meal allows significant savings

摘要

Many still believe that basically all soybean meal has similar nutrient value especially if they have the similar proximate analysis. However in recent years there is increasing evidence that different soybean meals can have different apparent metabolizable energy (AME) and protein efficiency ratio (PER). Jiang ZR (2004) demonstrated that different soybean meal can have very different AMEn (Fig 1). Subsequently the work of Neoh and Ng (2006) clearly showed that different soybean meals can have very different measured AME and PER and can perform very differently in poultry feeding trials. More recently Creswell (2008) measured the nutritional differences between soybean meals and by conducting a broiler feeding trial, he managed to quantify nutritionally and financially the differences between soybean meal.
