El papel de las hormonas en el estrés porcino
The role of hormones in the stress of pigs
Resumen
El estrés en los animales productores de carne tiene repercusión en la calidad de la carne y los productos que se obtiene de éstos. En la industria cárnica el problema más común relacionado con el estrés es la carne de baja calidad por ser pálida, blanda y exudativa. En esta revisión se presenta una breve reseña de la metodología del estrés y su interacción con la fisiología y el comportamiento animal. Se describen las hormonas relacionadas con el estrés, cual es su origen y algunas las posibles técnicas de diagnóstico. Se enfatizan las hormonas relacionadas con el músculo y los principales efectos en la fisiología del animal. Se mencionan los cambios neuroendócrinos y cuáles son sus mecanismos. Se describen con detalle las hormonas glucocorticoideas, el cortisol, la serotonina, la dopamina y los ß-adrenérgicos, así como sus principales características y efectos en el organismo vivo.
