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…
Perinatal flavour learning through the maternal diet is known to enhance flavour preference and acceptance of flavoured food in many species, yet still little is known about the mechanism underlying perinatal flavour learning. Previously we found positive effects of perinatal flavour learning on food intake, growth and behaviour of piglets…
The purpose of this study was to determine oro-sensorial preferences of recently weaned calves for 6 protein ingredients (corn gluten meal, distillers dried grain from wheat, pea meal, rapeseed meal, soybean meal, and sunflower meal) and to assess whether oro-sensorial preferences would remain when ingredients are presented as a part…
We have shown that the porcine umami taste receptor T1R1/T1R3 is present in pig’s gut and its expression increases in the small intestine after weaning. The aim of this study was to determine if the expression of the pT1r1/pT1r3 genes in taste and gut tissues changes in response to variation…
This study determined whether early experiences of sheep with the same feed, but presented in multiple or single flavors, would influence intake, the profile of hormones involved in feed intake regulation, and the subsequent acceptability of novel feeds. Thirty-five 2-mo-old lambs were randomly assigned to 5 treatments (7 lambs/treatment). Lambs…
The effects of including the same flavor additive in a milk replacer (MR) and a starter to facilitate a sensorial association between the flavor of starter and that of the MR were explored in an attempt to encouraging calves to increase solid feed consumption around weaning. Twenty-two male Holstein calves…
This study was conducted to evaluate the effects of flavor supplementation on pre- and post-weaning performance and behavior of piglets and sows. A total of 30 sows (LandraceYorkshire) and their litters were employed in this study. Sows were randomly assigned to 3 dietary treatments (10 replications per treatment). Dietary treatments…
