¹CR and CH: control (0 g FYC/kg). SH: treatment/supplemented with 700 mg/kg of FYC. CH and SH group birds exposed to 39°C for 4 h under controlled conditions from 21 to 23 weeks of age and also from 25 to 29 weeks after exposure. ²From 21 to 23 weeks of age, CH and SH group birds were exposed to 39^oC for 4 h under controlled conditions. CR: birds exposed to normal ambient room temperature. ³From 25 to 29 weeks of age, all the groups were exposed to ambient temperature in the shed after exposure. ^a,bIn a row, values with different superscripts are significantly different from each other ().
