A total number of 288 21-dayold male Ross broilers were distributed in a 2 x 2 2 factorial arrangement, with six replicates, including the following factors: two environments (TNE – thermoneutral: 21-25°C and 73% RH; CHS – cyclic heat stress: 25-32°C and 65%RH), and two diets (control: 2.4% soybean oil and 19.5% protein; summer: 4.0% soybean oil and 18.5% protein). In TNE, two additional treatments were included with feed restriction of birds fed both the control and summer diets (pair-feeding), thereby maintaining the same feed intake level for both types of diet.
