EFFECTS OF HIGH STARCH AND SUPPLEMENTATION OF AN OLIVE EXTRACT ON THE GROWTH PERFORMANCE, HEPATIC ANTIOXIDANT CAPACITY AND LIPID METABOLISM OF LARGEMOUTH BASS (MICROPTERUS SALMOIDES)

15/03/2022

An 8-week feeding trial was conducted to investigate the effects of high-starch diets and the supplementation of an olive extract (OE) on the growth performance, liver health and lipid metabolism of largemouth bass (Micropterus salmoides). Four isonitrogenous and isolipidic diets were prepared: two basal diets containing low (9.0%) and high…

EVALUATION DE LA CONDITION PHYSIOLOGIQUE DE PORCELETS SEVRÉS APRÈS EXPOSITION AU STRESS SOCIAL

01/02/2022

Weaning stress causes gut-barrier dysfunction partly by triggering the release of corticotropin releasing factor (CRF) and thereby inducing degranulation of intestinal mast cells, which in turn results in intestinal dysfunction that compromises piglet’s welfare. The aim of this study was to evaluate how mixing (social stress) influences the physiological condition…

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

01/02/2022

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

01/01/2022

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

01/09/2021

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)…

EFFECT OF A SENSORY ADDITIVE ON SOW REPRODUCTIVE PERFORMANCE

01/07/2021

RESUMEN: The addition of a sensory additive to sow diets during the summer improved feed intake during lactation, and litter performance. The aim of this study was to evaluate the impact of the sensory additive on sow lactation performance during cooler temperatures. Three consecutive groups (n = 61 total) of…

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

01/07/2021

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 THE DEGREE OF FASTING IN GUT PERMEABILITY OF UNWEANED ANGUS-HOLSTEIN BULL CALVES

01/07/2021

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, SOCIAL, AND IMMUNE-RELATED STRESS IN PIGS

01/06/2021

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

01/05/2021

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.
