“…The IP injection of 0.5-1 nmol/bird of ghrelin increased feed intake, while 3 nmol/bird and ICV injection of 0.5-1.0 nmol/bird decreased feed intake in Japanese quail [45]. IV administration of acyl-ghrelin at 1 nM/100 g BW/d suppressed feed intake, whereas des-acyl-ghrelin improved feed intake [46]. These findings suggest that these inconsistent outcomes may be attributed to the differences in doses, forms (e.g., acyl-and des-acyl-ghrelin), and injection routes.…”

This review focuses on the role of hormones derived from enteroendocrine cells (EECs) on appetite and nutrient absorption in chickens. In response to nutrient intake, EECs release hormones that act on many organs and body systems, including the brain, gallbladder, and pancreas. Gut hormones released from EECs play a critical role in the regulation of feed intake and the absorption of nutrients such as glucose, protein, and fat following feed ingestion. We could hypothesize that EECs are essential for the regulation of appetite and nutrient absorption because the malfunction of EECs causes severe diarrhea and digestion problems. The importance of EEC hormones has been recognized, and many studies have been carried out to elucidate their mechanisms for many years in other species. However, there is a lack of research on the regulation of appetite and nutrient absorption by EEC hormones in chickens. This review suggests the potential significance of EEC hormones on growth and health in chickens under stress conditions induced by diseases and high temperature, etc., by providing in-depth knowledge of EEC hormones and mechanisms on how these hormones regulate appetite and nutrient absorption in other species.
