they are related to the estrogen receptors, and may exhibit estrogenic and anti-estrogenic effects. They are present in
many plant nutrients (including soy, alfalfa, flax seed). The main sources of isoflavones are legumes and there are known
commercial preparations of isoflavones, which are natural, safe and alternative materials that can provide an effect similar to
estrogen. These compounds have effects on the health status, production characteristics of the animals (poultry, pigs), and the
characteristics of the final product ingredients.
