Dietary supplement to the feed based on zeolite for birds. Due to the porous structure of aluminosilicates (SiO2 and AlO4), negatively charged ions of potassium, magnesium, silicon (up to 40 mineral elements), and water molecules, it allows capturing substances in liquid, gaseous, and solid form and, if necessary, decompose them. At the same time, it not only takes harmful substances from the bird's body, but also gives it useful mineral elements.
