Chickens were fed diets containing 0% (control), 0.1%, and 0.4% solubles from shredded, steam-exploded pine particles from the 8th day to the 35th day of age. From 28th day to the 35th day of age, birds were either kept at a thermoneutral temperature (21.0°C) or exposed to cyclic heat stress at 31.0°C for 6 h daily. Data show mean ± SEM (n = 7).
Abbreviations: HS, heat stress; NT, normal temperature; Temp, temperature.
