| A total of 960 one-day-old Hybrid poults was used to study the influence of the origin of the soybean meal (SBM) and the supplementation with an enzyme mixture (ES) on performance from 1 to 28 d of age. There were 4 diets arranged factorially with two sources of SBM (ARG, Argentinean; USA) and two levels of ES (0 vs. 50 mg/kg of diet). The CP, trypsin inhibitor units (TIU), and KOH solubility for the ARG and USA SBM were 47%, 5.9 mg/g, and 81.2%, and 48.3%, 3.4 mg/g, and 86.8% respectively. The ARG meal was obtained from a local trader and the USA meal (SOYMAX trademark) from Owensboro Grain Co (Owensboro, KY). The calculated digestible lysine and AMEn content of these two SBM sources were 2.54 and 2.68%, and 2,310 and 2,390 kcal/kg, respectively. The enzyme complex used (Rovabio, Adisseo, St Antony, France) contained 14,000 IU of ß glucanase/kg diet, 20,000 IU of xylanase/kg diet, and included some additional amounts of other enzymes. The experimental diets were based on SBM and corn, and had similar AMEn, CP content, and essential amino acids profile (2,700 kcal AMEn/kg, 26% CP, and 1.4% digestible lysine) on calculated bases. Diets were fed as crumbles. Origin of SBM did not affect performance from 1 to 14 d of age but cumulatively, poults fed USA SBM had higher BWG (36.98 vs. 35.28 g/d, P<0.01), ADFI (52.82 vs. 51.37 g, P<0.05), and better FCR (1.43 vs. 1.46, P<0.05) than poults fed ARG SBM. Growth performance was not affected by ES. We concluded that SBM of USA origin had more AMEn and digestible lysine than SBM of ARG origin and that its inclusion in the diet resulted in better performance of poults from 1 to 28 d of age. The supplementation with enzymes did not affect performance of poult fed a corn-SBM diet at early ages. | |
