En cualquier especie animal, la modulación del comportamiento ingestivo implica cambios en su patrón de consumo en el corto plazo, el cual se evalúa teniendo en cuenta la distribución, el número, el tamaño y la duración de las comidas a lo largo del día, partiendo de la base de que…
Bile acids (BA) have recently emerged as regulators of intestinal immune homeostasis and mucosal integrity. We examined the effects of administering enterally deoxycholic acid (DCA) to early-weaned pigs challenged with lipopolysaccharide (LPS) on gut BA profile, immune response and microbiota. Twenty-four piglets were weaned at 21 d, acclimatized for 14…
Introduction: The aim of this study was to evaluate deoxycholic acid (DCA) ability to prevent lipopolysaccharide (LPS)-associated intestinal and systemic adverse effects when enterally administered to early-weaned pigs. Materials and Methods: Twenty-four piglets were weaned at 21 d, acclimatized for 14 d, and subsequently grouped (n=8) to be intragastrically infused…
Background: Previous work showed that weaning stress causes gut barrier dysfunction partly by triggering the release of corticotropin releasing factor (CRF) and thereby inducing the degranulation of intestinal mast cell (MC). This study investigated the hypothesis that attenuating the weaning-induced activation of the CRF-MC axis via administration of a MC…
Early weaning (EW) results in a transient period of impaired integrity of the intestinal mucosa that may be associated with reduced plasma concentration of glucagon-like peptide-(GLP) 2. We have previously shown that intragastric infusion of chenodeoxycholic acid (CDC) increases circulating GLP-2 in early-weaned piglets. The aim of this study was…

The present work aimed to identify the nutritional characteristics that best explain cereal feed preference in pigs. A total of 25 cereals of known preference (at 60% of inclusion in complete feed) from a previous study were evaluated. The cereals were analyzed for DM, OM, crude fiber, ether extract, CP,…
Flavour cues present in amniotic fluid are used in mammals to find their mother early, but they are also useful for having contact with environmental flavours before birth. Three experiments have been performed to evaluate if piglets, during lactation and post-weaning, have the ability to prefer natural or artificial cues…
Introducción La percepción sensorial (gusto, olor, textura, y señales gastrointestinales) ayuda a los animales a relacionar los alimentos con su calidad nutricional, influyendo de este modo la capacidad que los mismos poseen de afectar el apetito. En particular, la estimulación gustativa tiene efectos directos sobre procesos neurofisiológicos que estimulan el…
The symposium titled “Gut chemosensing: integrating nutrition, gut function, and metabolism in pigs” preceded the 12th International Symposium on Digestive Physiology of Pigs that was held in Keystone, CO, from May 29 to June 1, 2012. The objectives of the preconference symposium were to provide a comprehensive overview of the…
