Impact of heat stress on broilers with varying body weights: Elucidating their interactive role through physiological signatures

Abstract Physiological determinants of different body weight (BW) broiler chickens under heat stressed conditions were investigated to compare the performance at market age considering medium body weight group as standard. At 5 weeks, broilers were categorized randomly into 3 treatments (N = 24 per group) as high (HBW) (>1050 g), medium (MBW) (900–1050 g) and low (LBW) (
