1. IntroductionIntense genetic selection, combined with an effective feeding program and efficient rearing management greatly improved productivity and efficiency of broiler production [1]. Despite the low genetic variation and well-controlled rearing environment in modern broiler production, there can still be noticeable variations in body weight (BW) within a flock [2]. Ideally, broiler producti ...

IntroductionWhereas modern broilers have low genetic variation and wellcontrolled rearing environment, there are still high variations in BW within a flock (Lundberg et al., 2021). While uniformity is a universal issue in poultry production, there are still no cost-effective interventions other than culling heavy and small birds to improve uniformity within a broiler flock (Choi et al., 2026).
