Mycotoxicosis caused by zearalenone in pigs

There is a global increase of cereal contamination by fungi of the genus Fusarium, that has led to an increase in the concentrations of zearalenone in feed. Zearalenone is a mycotoxin that produces an estrogenic syndrome in prepubertal and fertile females, as well as abortions in pregnant females. One of the most obvious signs in the appearance of vulvitis, as can be seen in the image. Differential diagnosis should consider the differences between this mycotoxicosis and the one caused by ergotamine. Ergotamine affects reproduction too, but also affects the entire circulatory system and generally is only associated with the inclusion of rye in animal diets, a cereal where the fungus that produces ergotamine proliferates (Claviceps purpurea)
