Palabras clave: Vitamina A, vitamina E, hierro, niveles séricos, cerdos destetados


Se determinaron los niveles séricos de vitamina A, E y hierro en cerdos de granjas porcícolas del Municipio de Hermosillo, Sonora, México, ya que actualmente se carece de información de estos micronutrientes en esta región. Se muestrearon 4 granjas, en donde se tomaron muestras de sangre en base al 5 % la población total de cerdos en etapa de destete (21 ± 5 días de edad). Las vitaminas A y E se determinaron por HPLC. El hierro sérico y la capacidad total de fijación de hierro se determinaron por espectrofotometría. Las concentraciones de vitamina E mostraron variación entre granjas, los cerdos de las granjas 1 (3,4 µg/mL) y 2 (3,2 µg/mL) mostraron valores más altos de vitamina E (p<0,001) respecto a las granjas 3 (2,6 µg/mL) y 4 (1,6 µg/mL). Para la vitamina A y hierro no se encontraron diferencias entre granjas. En la granja 3 se evaluaron estas vitaminas y hierro en los días 1, 11, 18 y 25 posdestete y se encontró una disminución en la vitamina E en la primera semana, mientras que los niveles de vitamina A y hierro aumentaron. En este estudio, no se encontraron deficiencias de las vitaminas A y E, ni en hierro en cerdos.
