The glucagon-like peptide-2 (GLP-2) is a gut hormone released by intestinal L-cells in response to different stimuli, including the hormonal signaling of bile acids, such as chenodeoxycolic acid (CDC). This pleiotropic hormone may be implicated in post-weaning disorders induced by early weaning. The aims of this study were to confirm…
Palatability tests are a useful tool to assess the sensory properties of feed ingredients and additives. A training period is often necessary prior to testing so that animals become familiarized with the experimental procedure. However, little has been published on this topic and particularly with piglets. Three studies, using preference…
Early weaning is a stressful event characterized by a transient period of intestinal atrophy that may be mediated by reduced secretion of glucagon-like peptide (GLP) 2. We tested whether enterally fed bile acids or plant sterols could increase nutrient-dependent GLP-2 secretion and improve intestinal adaptation in weanling pigs. During the…
A double choice test was conducted to determine preference of diets with free L‐valine (L‐Val) in pigs under different nutritional status. One hundred and eight piglets (17.5 ± 1.5 kg BW) were divided into three groups and adapted for one week to diets that were either deficient (D), adequate (A)…
Weaning is a stressful event characterized by a transient period of anorexia and intestinal atrophy. The weaning-induced intestinal atrophy may be partly mediated by reduced secretion of glucagon-like peptide 2 (GLP-2), a trophic gut peptide secreted in response to luminal nutrition. We conducted 2 trials to investigate the hypothesis that…
Interest on strategies aiming to improve feed efficiency and prevent excessive fat deposition in fattening pigs is growing. We have hypothesized that triggering sensory and gastrointestinal satiety through flavoring compounds may contribute to achieve such a goal by reducing over-consumption of feed without compromising animal growth. To test this hypothesis,…
Dietary protein content is being reduced in weaned piglet diets due to intestinal health and environmental reasons. Therefore, the strategy is to supply these diets with appropriate synthetic amino acid supplementation to meet weaned piglet requirements. According to previous data, piglets with an adequate dietary supply of Lysine (Lys; 13.2…
Sugars and artificial sweeteners are sensed by the sweet taste receptor T1R2/T1R3 present in taste buds. Recent studies in rodents showed that this receptor is also present in the gut forming part of the mucosal chemosensing system by which luminal glucose and other chemicals are sensed to trigger gut physiological…
Young animals can learn about flavors from the maternal diet that appear in the amniotic fluid and mother’s milk, which may reduce neophobia for similarly flavored food types at weaning. Flavor learning may be beneficial for piglets, which after the rather abrupt weaning in pig husbandry frequently show a period…
The chemosensorial system of pigs has evolved to identify individual amino acids as indicators of protein in the feed, and therefore the palatability of the diet could be affected by the addition of free amino acids. A double choice test was conducted to determine the preference of diets with different…
