Chicks were randomly allocated to three treatments in six cages (replicates)
of five birds per cage in three-tiered battery cages with wire mesh floor. The three dietary treatments were:
(i) basal corn-soybean based diet (control), (ii) basal diet supplemented with 0.5% OligoPKE and (iii) basal
diet supplemented with 1% OligoPKE. The birds were fed a starter diet from day 1–21, and the finisher diet
from day 22–35 (Table 1).
