1 Values are mean ± standard error, n = 6. The values having different superscript letters are different (p < 0.05). CON, thermoneutral (24 °C for 24 h/d); HS, heat stress (35 °C for 4 h/d followed by 24 °C for 20 h/d); HSC, heat stress with 200 mg/kg COS supplementation. 2 CON group vs. HS group. 3 HS group vs. HSC group.
