The experiment to evaluate the replacement of Soybean meal (SBM) by Extruded Full-fat soybean meal (FF) or Extruded Express soybean meal (EXP) and its supplementation with or without enzyme (Avizyme). A total number of 630 unsexed one day-old Arbor-Acres, chicks were individually wing-banded, weighed and randomly distributed into 10 equal groups. An experimental corn-soybean meal starter-grower and finisher basal diets were formulated (21% CP & 2988 Kcal ME/Kg diet, at starter-grower and 19% CP & 3083 Kcal ME/Kg diet at finisher). Starting-growing period (1-4 wk), finisher period (5-6 wk). The levels of replacement were 30%, 70% of FF or EXP. The main results can be summarized as follows: 1)The birds were fed control or 70% EXP showed heavier BW, more BWG and performed more GR than other treatments during the growing period (first 4 weeks). 2)The results of FI showed no significant differences between soybean sources and levels treatments. 3)The best FCR was obtained by...
