  1. C control group, birds fed a corn-soybean basal diet without, N. oculata, TR1 birds fed the basal diet supplemented with 0.5% of N. oculata, TR2 birds fed the basal diet supplemented with 1.0% of N. oculata.
  2. a–cMeans followed by different letters in superscript in the same row differ significantly (P < 0.05). ± SM, standard error of means. Number of samples: 30 chickens (30n).
