Extruded vs. solvent-extracted soybean meal in early-lactation diets
Andrés Haro & Fernando Diaz
The use of extruded soybeans (ESM) has been adopted by dairy farms because of high nutritional value. It is an excellent source of protein, and particularly high in the essential amino acid lysine. Solvent-extracted soybean meal (SSM) has quite a stable nutrient composition (view table), with higher protein concentration (54.3% DM) and lower in fat (1.3% DM), compared to the ESM (50.1% protein and 8.7% fat). In addition, ESM has higher bypass protein content of 49.5% whereas SSM has only 29.9%.
