Abstract in italiano della tesi: The present work has been divided into two parts. At first, research projects attempt to evaluate technologies that increase digestibility of energy and other nutrients in cereal grains and their co-products. Differences in starch digestibility have been attributed to various factors, including the the type of corn endosperm, the presence of proteins and prolamins, the presence of lipids, the amylose-amylopectin ratio, the starch granule structure, the particle size, the conservation and processing methods. Second part of my work was dedicated to investigate the sensors of diet compounds which could be considered as potential markers to monitor nutrition status of organism. Activation of these receptors is believed to influence the hunger-satiety cycle, and their expression levels may be altered by dietary composition. Thus, the aim was to investigate for the first time the effect of arabinoxylans (AX) and β-glucans (BG) on the relative level of expression of carbohydrates, amino and fatty acid nutrient sensors genes in porcine oral and non-oral tissues.
