Abstract

Introduction Intensive selection of poultry breeds specially for superior growth has been shown to often lead to disturbance in various body hemostatic system including energy balance regulatory pathway. Dysregulation in appetite/satiety systems may eventually result in excessive fat accumulation and cause metabolic disorders. Accordingly, compared to native chicken breeds, most of commercial lines of broilers exhibit a greater appetite when given unrestricted access to feed. Furthermore, maternal Programming effects on the offspring metabolism, appetite and brain function was also demonstrated in different types of animal models, but the underlying physiological mechanisms involved remain unclear. Importantly, it has been suggested that this hyperphagia could be due to any defect or perturbation in signal transduction pathway of the appetite regulatory mechanism. Several lines of studies have shown that the involvement of hypothalamic AMP‐activated protein kinase (AMPK) in senses and maintains whole-body energy balance by regulating expression of various metabolic pathways-related genes. Accordingly, numerous brain neuropeptides including NPY, have been shown to participate in regulation of appetite and satiety. The aim of this study was to investigate the breed specific effects of yolk component on the post-hatch performance and expression of appetite-related genes in the diencephalon region of the progeny's brain.
