EFFECT OF A SENSORY ADDITIVE TO MAXIMIZE SOW FEED INTAKE AND PERFORMANCE OF PIGLETS DURING LACTATION UNDER HEAT STRESS CONDITIONS

Longevity of the sows is a major concern in pig production, which is negatively affected when the sow body condition is not properly restored shortly after weaning. Therefore, feed intake (FI) becomes crucial to prevent the excessive body reserve mobilization during lactation, but also in promoting milk production and therefore…

A STANDARDIZED OLIVE POMACE EXTRACT MAINTAINED SIMILAR PIGLET GROWTH PERFORMANCE TO HIGH LEVELS OF ZnO

The impending EU ban on using high ZnO levels (3,000 ppm) in weanling pig diets has accelerated the search for alternative solutions aiming to prevent post-weaning diarrhea while maintaining piglet performance in the nursery period. A standardized olive pomace extract (PE1, recommended dose: 0.25%), with anti-inflammatory properties, and a rosemary…

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

The intense nature of pig production has increased the animals’ exposure to stressful conditions, which may be detrimental to their welfare and productivity. Some of the most common sources of stress in pigs are extreme thermal conditions (thermal stress), density and mixing during housing (social stress), or exposure to pathogens…

ILEUM TRANSCRIPTOMIC PROFILING POST-WEANING PINPOINTS DIFFERENCES IN INTESTINAL PHYSIOLOGICAL STATUS AND MATURITY BETWEEN LIGHT AND HEAVY WEIGHT WEANED PIGLETS

Today’s swine industry increasingly relies on hyperprolific sows, entailing challenges related to heterogeneous and numerous litters having lower viability and poorer adaptation to weaning. This study compared the intestinal transcriptome of piglets with differences in body weight (BW) at weaning, to explore mechanisms underlying differences in adaptation and growth during…

POTENTIAL OF ORAL NANOPARTICLES CONTAINING CYTOKINES AS INTESTINAL MUCOSA IMMUNOSTIMULANTS IN PIGS: A PILOT STUDY

Antimicrobial resistance is a global threat that is worryingly rising in the livestock sector. Among the proposed strategies, immunostimulant development appears an interesting approach to increase animal resilience at critical production points. The use of nanoparticles based on cytokine aggregates, called inclusion bodies (IBs), has been demonstrated as a new…

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

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…

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)…

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.
