The influence of hydrothermal processing on protein quality and standardized ileal amino acid digestibility of soybean meal and rapeseed meal in pigs

In the European Union the production quantity of oilseeds (e.g. soybean (SB) and rapeseed (RS)) and their protein-rich by-products increase due to the ban of meat and bone meal and its by-products in diets for livestock (Commission Regulation, 2001) and furthermore due to an increase of biodiesel processing (Lywood and Pinkney., 2012). In the fiscal year 2014/2015, 296 million tons of oilseed meals (OSM) have been produced worldwide (USDA, 2015). Of the total global production of OSM, soybean meal (SBM) represents 68%, followed by 14% rapeseed meal (RSM), 5% cotton seed meal, 5% sunflower seed meal and 3% palm kernel meal (USDA, 2015).
