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…
Sodium butyrate (SB) is often used as an additive for milk replacers (MR) to improve calf performance. Tributyrin (TRB) is a triglyceride containing equivalent amount of butyrate than SB but in a more stable form. The aim of this study was to evaluate the effects of supplementing a MR with…
Butyrate in the form of sodium butyrate (SB) is often used as an additive for milk replacers (MR) to improve calf and piglet performance. Tributyrin (TRB) is a triglyceride containing equivalent amounts of butyrate than SB but in a more stable form. Thirty-six Holstein calves (45.7±5.9 kg of BW and…
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…
Thirty-two crossbred lambs (BW = 31.2 ± 4.7 kg; 16 females, 16 males) housed in individual pens were used to investigate the relationship between nutrient supply and taste preferences in ruminants. Experiment 1 determined whether an imbalanced CP supply would alter preferences for feeds containing flavors designed to elicit either…
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,…
A series of preference assays were conducted, using 2-month old 135 Holstein calves (65±0.3d of age), to develop an experimental method aimed at evaluating oro-sensory preferences in weaned calves. First, 35 calves (65±0.7d of age) were used to describe the typical eating pattern to determine the optimum moment to conduct…
