Effects of Zearalenone in Ruminants
PDF Chapter from Zearalenone Compendium
Zearalenone is a one of the mycotoxins commonly found in ruminant diets. Due to its structural similarity to estrogen, fungi-produced zearalenone latches onto the estrogen receptor, which can induce hyperestrogenism and lead to lower reproductive performance in cows, goats and sheep.
Zearalenone reduces reproductive efficiency in dairy and beef cattle, which can result in fewer calves being born, false heats, uterine prolapse, ovarian cysts, unsuccessful insemination or abortions.
BIOMIN has compiled all of the latest research on the effects of zearalenone in ruminants in the new book, Zearalenone Compendium.
According to Professor Qendrim Zebeli, head of the Institute of Animal Nutrition and Functional Plant Compounds at the University of Veterinary Medicine Vienna, “By the degradation of zearalenone in the rumen we do not have a detoxification. Rather, we have an upgrade of the toxicity and this is unfortunately due to the metabolites that are being released in the downstream degradation in the rumen which is mainly the alpha type, α-zearalenol, which studies indicate that the estrogenicity is much higher than the mother molecule.”
