Cover Story: Soybeans are a common ingredient of animal feed. They contain isoflavones, which are known to act as phytoestrogens in animals. Isoflavones were described to have beneficial effects on farm animals, but there are also reports of negative outcomes after the consumption of these phytoestrogens. This review summarizes the current knowledge of the metabolization of isoflavones (including the influence of the microbiome, phase I and phase II metabolism), as well as the distribution of isoflavones and their metabolites in tissues. Published studies on effects of isoflavones in livestock species are reviewed. Furthermore, occurrence data of isoflavones in feed and their co-occurrence with the mycotoxin zearalenone are provided and are supplemented with our own survey data. View this paper.
