  1. Different lowercase letters in columns show significant level (p < 0.05) according Student Newman Kwels test (SNK)
  2. aT1—control diet without enzyme and with available phosphorus according Tables for Broilers (Rostagno 2005); T2—250 FTU/kg of feed and 33 % more phytic phosphorus than T1; T3—500 FTU/kg of feed and 33 % more phytic phosphorus than T1; T4—250 FTU/kg of feed and 66 % more phytic phosphorus than T1; T5—500 FTU/kg of feed and 66 % more phytic phosphorus than T1; FTU—phytasic unit
  3. bns—not significant with 5 % of significance
  4. cCV—coefficient of variance
