Gut Hormones and Regulation of Food Intake in Birds

Abstract: Gut hormones act as appetite regulatory hormones in mammals. For example, the hunger hormone ghrelin, which is released from the stomach before food intake, stimulates appetite. In contrast, satiety hormones such as cholecystokinin, glucagon-like peptide-1, and peptide YY, which are released from the intestines after food intake, suppress appetite. The effects of these peptides on food intake have been shown to be similar in both mammals and fishes. However, evidence suggests that the physiological roles of th… Show more

“…However, the molecular mechanisms underlying the IGF-1-induced anorexia in chicks have not been investigated. Physiological and molecular mechanisms involved in the regulation of food intake in chickens have recently been investigated (Kuenzel, 1994, Richard andProszkowiec-Weglarz, 2007;Honda et al, 2017). In mammals and birds, two neuronal populations within the hypo-thalamus, namely, the orexigenic neuropeptide Y(NPY)/agoutirelated protein (AgRP) neurons and the anorexigenic proopiomelanocortin (POMC) neurons, are believed to be critical conduits via which peripheral signals are integrated to alter the drive to eat (Bungo et al, 2011;Sam et al, 2012;Zeltser et al, 2012).…”

“…Therefore, gut mucosa plays a crucial role in bird's physiology since it must be permeable to nutrients, electrolytes and water, and at the same time is a barrier against bacteria and antigens translocation to the lamina propria. In addition, the small intestine also has an important immunological, endocrine and regulatory function (Scanes & Pierzchala-Koziec, 2014) which can deeply affect health status (Sugiharto, 2016), as well as feeding behaviour and overall energy homeostasis in the chickens (Honda, Saneyasu, & Kamisoyama, 2017).…”

“…It stimulates insulin secretion from the pancreatic islets in mammalian species. The mRNA of proglucagon, which acts as the precursor of GLP-1, is highly expressed in the ileum of the chicken alimentary tract (Honda et al, 2017). In chickens, GLP-1 is stored in the secretory granules of L cells, which are mainly distributed in the distal ileum (Hiramatsu et al, 2003(Hiramatsu et al, , 2005Nishimura et al, 2013) and is secreted in response to dietary protein and amino acids (Monir et al, 2014a;Nishimura et al, 2015).…”
