Table 4 Effect of experimental diets on performance parameters of broilers over different growth periods. Mean values are based on 18 birds per replicate and 11 replicates per treatment. ^a–c values in a row with no common superscripts differ significantly (P ≤ 0.05) – Tukey test; ¹FCR values corrected to the mean body weight gain (1–35 d) of INO group.
