National Research Council (NRC, 1994). The experimental period include starter (0 to 21 day) and grower
(22 to 42 day). The birds were grown on floor pens (120 × 100 × 80 cm) for 42 days and in total periods had
free availability to feed and water. At during the experimental period, chicks were exposed to 23hr light and
1hr dark. The house temperature was kept at 32oC for the first week and it was reduced by 3oC in following
