Taste perception of sweet and umami stimuli in vertebrates is largely controlled by a family of G-protein-coupled receptors, the taste receptor type 1 (T1R) family, with three members that combine in heterodimers to form the taste receptors. The mammalian T1R1/T1R3 receptor responds to umami compounds such as amino acids, whereas…
Nutrients from the ingested food interact with sensors along the mammalian digestive tract. These sensors, through vagal afferent nerves, can activate brain areas related to the control food intake. In the oral cavity, as a first stop of the food, umami taste receptors can detect the presence of different amino…
The present study aims to investigate the effects of supplementing broiler diets with a bioactive olive pomace extract (OE) from Olea europaea on growth performance, digestibility, gut microbiota, bile acid composition, and immune response. To this end, three hundred and six 1-day-old broiler chickens (Ross 308) were housed in floor…
Two experiments were conducted to investigate effects of dietary flavor as a feed additive on growth performance of weaned pigs. The flavor used in experiments was a commercial product (Luctarom®, Lucta Guangzhou, China) containing milky cream flavor. In Exp. 1, 72 weaned pigs (initial BW = 6.51 ± 0.21 kg)…
This study was conducted to investigate effects of dietary flavor on immune responses and gut microbiota of weaned pigs. A total of 72 weaned pigs (initial BW = 6.66 ± 0.32 kg) were randomly assigned to 2 dietary treatments (4 pigs/pen; 9 replicates/treatment) in randomized complete block design (block =…
Introduction Extrusion is a technology widely used in feed processing that consists of combining high temperatures and high pressures to the feed material. The main objective when used in a final feed is to improve digestibility, but it can also be used in raw materials such as rice bran (Riaz,…
The present study aimed to evaluate the effect of two bioactive pomace extracts (OEa and OEb) from Olea europaea (Lucta S. A., Madrid, Spain) in broiler chickens challenged with an Eimeria spp vaccine. To this end, 560 1-d old male chicks (Cobb 500) were randomly assigned to 7 experimental treatments…
A previous study showed that the use of a capsicum oleoresin based additive (Luctarom Convert – LOM, Lucta S.A.) was able to improve dietary fat digestibility in broilers. The present study aimed to evaluate the effect of LOM on growth performance of broiler chickens under summer conditions in Spain, where…
Enteroendocrine L cells and GLP-2 secretion are activated in the intestinal adaptation process following bowel resection in short bowel patients. We hypothesized that enteral activation of Takeda G-protein-coupled receptor 5 (TGR5) expressed in enteroendocrine L cells could augment endogenous GLP-2 secretion and the intestinal adaptation response. Our aim was to…
