Dietary amino acids, gut sensing, and feed intake regulation in pigs
Abstract
Dietary amino acids (AA) regulate appetite by stimulating the release of gut hormones, such as ghrelin, CCK, GLP-1 and PYY, from enteroendocrine cells located throughout the gastrointestinal tract via the activation of GPCR transmembrane receptors. While most of the current literature available on the topic relates to research done in laboratory rodents, there has been a growing demand on the confirmation of these physiological processes in pigs. This presentation will cover the main gastrointestinal mechanism involved in the appetite modulatory role of AA identified to date, including previously unpublished data on AA-induced gut hormone release and satiety in pigs.
Dr Maximiliano Müller
Dr Maximiliano Müller completed his bachelor’s degree in Veterinary Science at the Universidad de Chile in 2015. In 2016 he was awarded a scholarship by the Chilean Government to perform a PhD program abroad. He recently obtained his PhD from The University of Queensland in May of 2021. During Maximiliano’s PhD studies under the supervision of Prof. Eugeni Roura at QAAFI, he investigated the effects of amino acids on appetite and the gastrointestinal mechanisms involved these processes in pigs. Maximiliano has been awarded two Best Student Oral Presentation: International Symposium Digestive Physiology Pigs 2018 and National Conference of Chemosensory Science 2017.
