¹10 and 20 days represent days during exposure from 21 weeks of age at 39^oC for 4 h under controlled conditions. ²CR: control maintained at ambient room temperature, CH: control (0 g FYC/kg), and SH: treatment/supplemented with 700 mg/kg of FYC. CH and SH group birds exposed to 39^oC for 4 h under controlled conditions from 21 to 23 weeks of age. ^a,b,cIn a row, values with different superscripts are significantly different from each other (). Values are represented as mean ± SE. N = 6 and 5 for hormone and enzyme studies, respectively.
