Chemical composition, protein quality indicators and in vitro protein digestibility of commercial soya bean meals from different origins for use in poultry feeding.

Soya bean meal (SBM) is the main source of crude protein (CP) and amino acids (AA) in poultry diets worldwide, with Brazil (BRA), the United States (US) and Argentina (ARG) as the main suppliers. From 2016 to 2021, Europe imported 31 million metric tons (MMT) of soya beans, the equivalent of which 40, 22 and 18% correspond to BRA, ARG and US, respectively (European Commission, 2022).
