A stable microbiota can act as an effective barrier against pathogen colonization besides to the production of metabolic substrates (e.g. vitamins, enzymes) and stimulate the mucosal immunity. Supplementation with probiotics have shown to improve the digestibility in pigs and work as an immunostimulant. The aim of this study was to assess the lipid metabolic profile in sows supplemented with Lactobacillus casei throughout a complete reproductive cycle. Eighteen F1 Landrace x Large White sows were randomly distributed in three experimental groups: control, T1 supplemented with 10 x 106 CFU (colony forming units)/g of L. casei and T2 supplemented with 10 x108 CFU/g of L. casei, administered weekly by oral route for 180 days, covering a reproductive cycle. Metabolites from lipid metabolic, hematic and protein profiles were analyzed in each sow at the day of service, 80-day and 113-day of pr...

Una microbiota intestinal equilibrada constituye una barrera eficaz contra la colonización de patógenos, además de producir sustratos metabólicos (e.g. vitaminas, enzimas) y estimular el sistema inmunológico de mucosas. La suplementación con probióticos ha demostrado mejorar la digestibilidad en cerdos y servir como inmunoestimulante. El objetivo del presente trabajo fue evaluar el perfil metabólico lipídico en cerdas suplementadas con Lactobacillus casei a través de un ciclo reproductivo. Se emplearon 18 cerdas F1 Landrace x Large White distribuidas completamente al azar en tres grupos: control, T1 suplementado con 10 x 106 UFC (unidades formadoras de colonias/g) de L. casei y T2 suplementado con 10 x 108 UFC/g de L. casei, con frecuencia de administración semanal por vía oral, durante 180 días, cubriendo un ciclo reproductivo. Se analizaron los metabolitos del perfil lipí...

The aim of this study was to evaluate the presence of the porcine circovirus 2 (PVC2) and the seroreactivity in pig farms in the regions of Tolima and Huila, Colombia, through a cross-sectional study. Blood and tissue samples (lymph nodes, lung and kidney) were taken from animals of all productive stages, including healthy animals and those with signs of the disease. The ELISA test detected seropositive animals in all productive stages. To identify the presence of the virus, the complete ORV2 of PCV2 was amplified by endpoint PCR using DNA extracted from blood, lymph nodes, lung and kidney. The samples were genotyped and finding positive animals for PCV2, both healthy and diseased, at all stages of production. Sequence analysis demonstrated a percentage of identity between 93 and 99% with the PCV2d genotype. Animals without positive clinical signs were positive for the ELISA test and for...
