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…
TOP 10% MOST DOWNLOADED PAPERS IN THE JOURNAL OF THE WORLD AQUACULTURE SOCIETY 2018-2019 Squid visceral paste is a popular attractant and feeding stimulator supplement in shrimp feeds in China, but it often faces problems with fluctuating availability, cost, composition, and quality. An 8-week experiment was performed to test a…
The Problem: The current need to find alternatives to the use of antibiotics utilization in animal feeds is opening opportunities for feed additives such as phytochemicals in poultry. The present study aims to investigate the effects of supplementing broiler diets with a bioactive pomace-oil extract from Olea europaea (OE) on…
Bitter taste perception acts as a signal to the central nervous system to warn animals against consuming potentially toxic substances. When bitter compounds activate bitter taste receptors, a signal reaches the brain that triggers an aversive response and activation of anorexic signals, hence reducing feed intake. The objective of the…
Recent studies suggest that the use of vegetable oils at expense of fish oil in aquaculture feeds might have potential negative effects on fish redox homeostasis and adiposity. Resveratrol (RESV) is a lipid-soluble phytoalexin present in fruits and vegetables with proven in vivo antioxidant function in animals. The present study…
Feeding behavior in dairy cattle has a significant impact on feed efficiency, which is important for increasing the profitability of livestock and, at the same time, reducing the environmental impact. Feeding behavior can be measured by feeding time, meal duration, meal frequency, feeding rate, and rumination time. Higher feed intake…
Fishmeal (FM) and fish oil are becoming strategic ingredients for aquaculture feeds. In spite of considerable efforts to replace FM by alternative ingredients, problems with reduced feed intake and growth, as well as gut health issues (intestinal integrity and inflammation) are still common, associated with a lower palatability, digestibility and…
