Summary This study was conducted to determine the chemical composition and standardized ileal digestibility coefficients ( SID ) of crude protein ( CP ) and amino acids ( AA ) of European soya bean and rapeseed products in pigs. Six soya bean and two rapeseed products were used as the sole dietary source of CP and AA , including raw ( FFSB ) and roasted full‐fat soya beans ( FFSB R oasted ), soya bean ( SBC ) and rapeseed cake ( RSC ), and rapeseed meal ( RSM ) from Bavaria (Germany), soya bean meal ( SBM ) from the Danube region (Austria; SBM A ustria ), a commercially available standard SBM ( SBM S td ) and an imported genetically modified organism‐free SBM ( SBM GMO ‐free ). Eight ileal‐ cannulated pigs with an initial body weight of 32 ± 2 kg were allotted to a row‐column design with eight diets and six periods of seven days each. Trypsin inhibitor activity ( TIA ) ranged from 1.8 in SBM S td to 24.5 mg/g DM in FFSB . The SID of CP and all AA in FFSB R oasted were greater than in FFSB , but lower when compared to SBC and SBM A ustria ( p < .05). The SID of CP and all AA (except glutamic acid) were not different between SBC and SBM A ustria , but the SID of CP and all AA (except methionine) were greater ( p < .05) in SBC than in SBM GMO ‐free . Furthermore, the SID of CP and most AA showed a quadratic response with decreasing TIA , and there exists a quadratic response in SID of CP and all AA with increasing lysine to CP ratio and neutral detergent insoluble nitrogen ( p < .05). In conclusion, variation in chemical composition and SID of CP and AA was observed in different European soya bean and rapeseed products as influenced by differences in processing conditions. European SBC and SBM A ustria can be used as alternative to imported SBM GMO ‐free and SBM S td in diets for growing pigs.
