We have previously obtained evidence on presence and functioning of central amino acid sensing systems in fish after intracerebroventricular injection of branched-chain amino acids (BCAA) L-leucine and L-valine. In hypothalamus these systems were activated by L-leucine but not by L-valine. The mechanisms involved are similar to those described in mammals:…
Over the past decade, sustainable aquaculture production promoting increasing dietary replacement of fisheries by plant ingredients has steadily grown, often reducing the palatability of fish diets and animal performance. However, very little information exists on taste-related mechanisms possibly underlying these effects. Vertebrate taste perception is largely controlled by two families…
A feeding trial was conducted to test the application of a Functional Palatability Enhancer (FPE) containing umami compounds in improving the feed palatability and performance of Snakehead fish fed low-fishmeal diets. Seven isonitrogenous (43% crude protein) and isolipidic (7% total lipid) test diets were formulated, where diet 1 was a…
Feed additives including flavours and umami compounds could be beneficial for improving palatability and functionality of fish diets, especially when dietary fishmeal is replaced by plant-based protein sources. Aimed to apply the proposed new strategy in shrimp production, the present study was designed to test the effect of supplementation of…
The aim of this study was to evaluate the inflammatory and intestinal integrity response of piglets fed with or without antimicrobials added to their transition diets. For this purpose, eighty piglets ((LD x LW) x Pietrain) were weaned at 21 d of age (6.4 ± 0.1 kg body weight (BW))…
Fibroblast growth factor-19 (FGF19) is an emerging endocrine factor involved in the regulation of bile acid homeostasis and energy metabolism in rodents and humans. In pigs, however, the FGF19 system remains largely unexplored. This study was designed to investigate the developmental regulation of the FGF19 system in domestic pigs. Samples…
To assess the hypothesis of central amino acid-sensing systems involved in the control of food intake in fish, we carried out two experiments in rainbow trout. In the first one, we injected intracerebroventricularly two different branched-chain amino acids (BCAAs), leucine and valine, and assessed food intake up to 48 h…
