Role of leptin and ghrelin in regulation of physiological functions of chicken

Leptin and ghrelin have been recognised to have a major influence on energy balance. Leptin is majorly secreted from brain tissues and ghrelin from proventriculus in chicken. Both are mediators of long-term regulation of energy balance and suppression of food intake. Both the hormones are having effect on reproduction and immunity. The manner in which both leptin and ghrelin systems in chicken contribute to the regulation of different physiological functions is still evolving. The hormones detected in embryo indicate their action in growth and development. This review provides recent information on the leptin and ghrelin hormones, their role in feed intake, body weight, reproduction and their mechanism of action in chickens.

Automated summary

Leptin and ghrelin are two hormones that have a major impact on energy balance and food intake suppression in chickens. They also affect reproduction and immunity. The regulation mechanisms of leptin and ghrelin systems in chickens are still evolving. This review provides recent information on the role of leptin and ghrelin hormones in feed intake, body weight, reproduction, and their mechanisms of action in chickens.
