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…
There is a lack of research on potential effects of supplementation on metabolic profile in grazing dairy cows. Therefore, 45 Holstein dairy cows (147 DIM, 544 kg BW) were assigned to a 3 × 3 Latin square design replicated 15 times to evaluate the effect of sensory additive compound by…
Forty-five Holstein dairy cows (147 d-in-milk and 544 kg BW on average) were assigned to a 3 × 3 Latin square design replicated 15 times to evaluate the effect of a sensory additive (ProEfficient, PE; Lucta SA, Barcelona, Spain) on milk response to concentrate supplementation on pasture. Cows were blocked…
The aim of this study was to evaluate changes in feeding behavior and performance of lactating dairy cows in response to the addition of sensory additives into their TMR. A 90-d experiment was conducted involving 42 lactating cows (15 primiparous, 27 multiparous; BW = 690 ± 63 kg; DIM =…
