| description |
The objective of this study was to evaluate the presence of heavy metals (arsenic, cadmium, mercury, and lead), Salmonella and E. coli, as well as mesophiles, fungi and yeast counts and Clostridium sulfite reductor count in concentrates for pigs in four regions of Colombia. Feed samples (n=38) were collected from 19 farms for the analysis of heavy metals. Samples were processed in triplicate and analyzed by plasma-coupled atomic absorption spectrometry. For the microbiological analysis, 391 samples from 22 farms were processed. For the detection of Salmonella, the MDS-3M equipment was used, and its presence was confirmed using Maldi-tof, while for the counting of E. coli cromocult agar was used. For mesophilic aerobes, the plate count agar was used and for the fungi and yeasts rose bengal agar. The results indicated that only two samples from the same farm had high arsenic values (2 ppm) while the other metals were within the expected limits. The counts of mesophiles, fungi and yeasts and Clostridium were within the Colombian regulations, with only one positive sample for Salmonella (0.25%), while 1% of the samples presented E. coli. The results reflect that the quality of concentrates used in pig feeding is not an important source of pathogens or heavy metals. |

Se recolectaron 38 muestras de concentrados de 19 granjas para el análisis de metales pesados. Las muestras se procesaron por triplicado y se analizaron mediante espectrometría de absorción atómica acoplada a plasma. Para el análisis microbiológico se procesaron 391 muestras de 22 granjas. Para la detección de Salmonella se usó el equipo MDS-3M y su presencia se confirmó usando Maldi-tof, en tanto que para el recuento de E. coli se usó agar cromógeno (Petrifilm); para los aerobios mesófilos se empleó el agar plate count, y para hongos y levaduras el agar rosa de bengala. Los resultados indicaron que solo dos muestras de una misma granja presentaron valores elevados de arsénico (2 ppm) mientras que los demás metales estuvieron dentro de los límites esperados. Los recuentos de mesófilos, hongos y levaduras y Clostridium estuvieron dentro de la reglamentación colombiana, habiendo solo una muestra positiva para Salmonella (0.25%), en tanto que el 1% de las muestras presentó E. coli. Los resultados reflejan que la calidad de los concentrados que se emplean en la alimentación porcina no son una fuente importante de patógenos o de metales pesados.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2018-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1477210.15381/rivep.v29i3.14772Revista de Investigaciones Veterinarias del Perú; Vol. 29 Núm. 3 (2018); 774-781Revista de Investigaciones Veterinarias del Perú; Vol. 29 No. 3 (2018); 774-7811682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/14772/13074https://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/14772/13885Derechos de autor 2018 Irina Barrientos, Iliana Chamorro, Corina Zambrano, Mónica Pérez, Nathaly González, Ana Karina Carrascalhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/147722018-12-21T09:58:01Z |
