THE SUPPLEMENTATION OF BROILER FEEDS WITH CAPSICUM BASED ADDITIVE IMPROVES ANIMAL PERFORMANCE. THE RESULTS OF A META-ANALYSIS.

Capsaicin isthe main active compound in capsicum oleoresin derived from red pepper (Capsicum spp.). Studies have demonstrated that the inclusion of plant extracts high in capsaicin can improve the productivity of broiler chickens. The meta-analysis is a useful tool to perform a joint analysis of different studies as it increases…

SIMULATION OF FEED RESTRICTION AND FASTING: EFFECTS ON ANIMAL RECOVERY AND GASTROINTESTINAL PERMEABILITY IN UNWEANED ANGUS-HOLSTEIN CALVES

RESUMEN: Feed restriction and fasting experienced during commercial production negatively affect unweaned calves’ behavior and health status. Transportation and stays at assembly centers are the main factors generating these disorders. For this study, 20 unweaned Angus-Holstein bull calves [44.1 ± 2.04 kg of body weight (BW) and 14.7 ± 0.63…

OLIVE OIL CAKE EXTRACT STABILIZES THE PHYSIOLOGICAL CONDITION OF LIPOPOLYSACCHARIDE-CHALLENGED PIGLETS BY REDUCING OXIDATIVE STRESS AND INFLAMMATORY RESPONSES AND MODULATING THE ILEAL MICROBIOME

RESUMEN: Olives are a rich source of compounds with antioxidant and anti-inflammatory activities. This study was designed to investigate whether a standardized olive cake extract was able to alleviate oxidative stress, inflammation and intestinal villus damage in a model of lipopolysaccharide (LPS)-challenged piglets. Thirty weaned piglets (6.9 ± 0.9 kg)…

IMPACT OF FEED RESTRICTION AND FASTING SUFFERED

IMPACT OF FEED RESTRICTION AND FASTING SUFFERED IN ASSEMBLY CENTERS AND TRANSPORTATION ON ENERGY BALANCE AND GUT PERMEABILITY IN UNWEANED ANGUS-HOLSTEIN CALVES

RESUMEN: Twenty unweaned Angus-Holstein calves (44.1 ± 2.0 kg; 14.7 ± 0.63 d) were used to evaluate the effects of feed restriction and fasting on energy balance (serum concentration of glucose, BHBA, and NEFA), and intestinal permeability (serum concentration of citrulline, Cr-EDTA, lactulose, and D-mannitol). Calves were randomly assigned to…

OPTIMIZATION OF INTESTINAL PERMEABILITY ASSAYS TO STUDY

OPTIMIZATION OF INTESTINAL PERMEABILITY ASSAYS TO STUDY THE DEGREE OF FASTING IN GUT PERMEABILITY OF UNWEANED ANGUS-HOLSTEIN BULL CALVES

RESUMEN: In-vivo assessments of intestinal permeability can be expensive and time consuming. Additionally, the correct choice of test molecules to use and the optimum sampling time under fasting situations needs be optimized. Fifteen unweaned Angus-Holstein bull calves (44.1 ± 2.0 kg and 14.7 ± 0.63 d) were randomly assigned to 1…

SYSTEMATIC REVIEW OF ANIMAL-BASED INDICATORS TO MEASURE THERMAL

SYSTEMATIC REVIEW OF ANIMAL-BASED INDICATORS TO MEASURE THERMAL, SOCIAL, AND IMMUNE-RELATED STRESS IN PIGS

RESUMEN: Intensification of pig production has increased the exposition of animals to stressful conditions that might be detrimental to their welfare and their productivity. Some of the most common sources of stress in pigs are extreme thermal conditions (thermal stress), density and mixing at housing (social stress), or exposure to…

PREVENTION IS BETTER THAN CURE APPLIED TO HEAT STRESS

PREVENTION IS BETTER THAN CURE APPLIED TO HEAT STRESS

RESUMEN: Heat stress produces a wide range of negative consequences, some of them with long-lasting effects. When livestock are subjected to this environmental stress, it can be detrimental to health, well-being, and performance. Setting up multiple strategies before heat stress strikes is crucial.

FIRST EVIDENCE FOR THE PRESENCE OF AMINO ACID SENSING MECHANISMS IN THE FISH GASTROINTESTINAL TRACT

RESUMEN: This study aimed to characterize amino acid sensing systems in the gastrointestinal tract (GIT) of the carnivorous fish model species rainbow trout. We observed that the trout GIT expresses mRNAs encoding some amino acid receptors described in mammals [calcium-sensing receptor (CaSR), G protein-coupled receptor family C group 6 member…
