Abstract
Two trials were conducted to study the influence of origin of soybean meal (SBM) on performance of broilers from 1 to 37 d of age. The CP, trypsin inhibitor units (TIU), and KOH solubility were 47% and 48.3%, 5.9 mg/g and 3.4 mg/g, and 81.2% and 86.8% for the Argentinean (ARG) and USA SBM, respectively. The calculated digestible lysine and AMEn content were 2.54% and 2,310 kcal/kg for ARG SBM and 2.68%, and 2,390 kcal/kg for the USA SBM. For each of the 2 periods, starter (1 to 21 d) and finisher (22 to 37 d), the diets had similar calculated AMEn and digestible lysine content. In trial 1, 5,200 straight-run, one-day-old Hubbard chicks were used. There were 4 treatments arranged factorially with two diets based on ARG or USA SBM and two birds strain (F15 and JV). Each treatment was replicated 10 times (a floor pen with 130 chicks). Origin of SBM did not affect performance at any age. Broilers from the F15 strain ate more feed (P<0.01) and grew faster (P<0.001) than JV broilers. In trial 2, 1,500 straight-run, one-day-old JV chicks were used. There were 6 treatments arranged factorially with 3 SBM sources (ARG, USA, and local) and two levels (0 vs. 250 mg/kg of diet) of plant oil extract rich in terpenes (AEN 1400, Phytosynthèse, Clairemont ferrand, France). The local SBM contained 47.3% CP and had similar calculated nutritive value than ARG SBM. Each treatment was replicated 5 times. Cumulatively, birds fed USA and ARG SBM grew faster (P<0.001), and had better FCR (P<0.01) than birds fed the local SBM. The inclusion of prebiotic improved BW gain and FCR in birds fed the local SBM but not in those fed the others SBM. The percentage of prime parts (breast, thighs, and wings) was lowest for birds fed the local SBM (P<0.05). We concluded that USA SBM had more AMEn and digestible lysine for broilers than ARG and local SBM. Also, the prebiotic used might improve performance in broilers fed low quality SBM.
