A total of 5,200 straight-run, one-day-old Hubbard chicks (half of the F15 strain and half of the JV strains) were used to study the influence of the origin of soybean meal (SBM) on performance from 1 to 37 d of age. There were 2 diets based on Argentinean (ARG) or North American (USA) SBM. Broilers were fed a starter (1 to 14 d), grower (15 to 21 d), and a finisher diet (22 to 37 d). For each of the 3 periods the 2 experimental diets had similar AMEn and digestible Lys content and the main difference between diets was the origin of the SBM used. Diet did not affect any performance trait at any age in spite of diet based on USA SBM having less SBM (1.2%) and less added soy oil (0.5%) than the diet based on ARG SBM. From 1 to 37 d of age broilers from the F15 strain ate more feed (P < 0.01) and grew faster (P < 0.001) than JV broilers. We concluded that USA SBM had more digestible lysine and AMEn than ARG SBM and that performance was better for broilers of the F15 than for broilers of the JV strain.
