We studied the effect of soybean meals (SBM) from USA, Brazil (BRA), and Argentina (ARG) on the apparent ileal digestibility (AID) of the amino acids (AA). In total, 500 one-day-old, straight run Ross 308 broilers were used. Nine SBM samples from 3 different origins, USA (n = 3), Brazil (BRA; n = 3), and Argentina (ARG; n = 3) were used in the study. The samples used were collected by trained personnel at the discharge of the cargos from the different countries. Each treatment was replicated 10 times and the experimental unit was a cage with 5 broilers. Birds were fed a commercial corn-soybean meal diet from 1 to 18 d of age in pellet form and then, their corresponding experimental diets in mash form. These diets that resulted from the combination of 42.6% SBM and 57.4% of a nitrogen free diet to 22 d of age. The nitrogen free diet was based on corn starch, dextrose, soybean oil, minerals, and solka-floc, and did not contain any protein source. Data were analyzed as a nested design using the MIXED procedure of SAS. The main effect of the model was the country of origin of the SBM and the nested effects were the SBM samples within origin and the cage within the SBM. When the model was significant, the Tukey test was used to make pairwise comparisons between treatment means. Although all SBM, regardless of origin, were similar to each other, in general, the AID of DM, CP, and of most AA (Lys, Met, and Thr) was higher for the USA meals than for the South American meals, although the differences were not significant.
