A total of 385 samples of soybean meal (SBM) from Argentine (ARG, 127), Brazil (BRA, 110) and USA (148) were collected and analyzed for major nutrients including amino acids and sugar content, and for quality variables of the crude protein fraction. On dry matter bases, SBM from USA had more CP (53.9 vs. 51.6 vs. 52.7 %; P<0,001), and less NDF (8.8 vs. 10.7 vs. 11.9%; P<0,001) than SBM from ARG and BRA. Sucrose and stachyose contents were higher for the USA than for the BRA meal, with ARG meal being intermediate (P<0,001). Also, ash and P and K contents, were higher (P<0.001) and the Fe content lower (P<0,001) for ARG and USA meals than for BRA meal. The PDI, KOH solubility and trypsin inhibitor activity were higher for USA than for ARG or BRA SBM (P<0,001). In addition, SBM from USA had more lys, met + cys, thr, and trp than SBM from BRA and ARG (P<0,001). It is concluded that the content in dietary components and the quality of the protein fraction favor the nutritive value of the SBM from USA origin with respect to the other two meals.
