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…
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 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…
Pigs perceive the umami taste via the pT1r1/pT1r3 receptor present in their tongue. In vitro studies, using a proprietary cell reporter system (CRS) that expresses this heterodimer, showed that it is tuned to detect amino acids (AA). The objectives of this work were (1) to evaluate preferences of piglets for…
Weaning is a stressful process in piglets, in which the adaptation to the weaning diet is one of the most limiting factors. The palatability of the weaning diet ingredients may play a determinant role. A series of double choice trials with 180 pigs (20-25 kg BW) in 45 pens, were…
Compromised voluntary feed intake of piglets in the post-weaning period might be improved by increasing feed palatability. Eighteen double choice tests with a total of 600 post-weaned pigs (20–25 kg BW), were conducted to determine preference for 14 acids and 4 salts compared with a control (REF) diet. Each test…
Four experiments were conducted to evaluate the palatability of sorghum, maize, rye and lupine for pigs. Diets containing sorghum, maize, rye or lupine (test diets) were offered in a series of double choice tests against a reference diet. To prepare the reference diets, white broken rice in the experiments with…
Umami is a taste quality sensing dietary protein born nutrients such as L-amino acids. Humans and mice perceive the umami taste via a trans-membrane heterodimeric receptor consisting of T1R1 and T1R3 proteins. Porcine umami taste receptors have been recently identified and reported in vallate papilla tissue samples. The pTas1r1 and…
The evolution of the chemical senses has resulted in a sensory apparatus for high taste and smell acuity in mammals and birds to ensure self-nourishment. Such peripheral chemosensory systems function as a code to unfold the nutritional value of feedstuffs. Food ingestion simultaneously evokes odor, taste and thermo-mechanical (somatosensing) sensations.…
A trial was conducted with 192 Landrace × Large White newly weaned 23d-old pigs to study different dosing programs of an enhanced milky flavor (Luctarom® Advance) in feeds. Piglets were randomly allocated in a factorial design with 3 blocks of 8 pens according to initial body weight (light=5,78 kg; intermediate…
