The aim of this innovative technical solution is an epigenetic supplement to a feed mixture for cattle containing 70 to 90% epigenetically active components and 5 to 15% by weight. taste masking ingredients and 5 to 15% by weight. to improve its hygroscopic properties. The epigenetically active components of the supplement are folic acid, the formula C19H19N7O6 5 to 25% by weight, zinc sulphate heptahydrate, the sum of formula ZnSO4.7H2O 15 to 35% by weight, Quercentine formula C15H10O7 10-30% To mask their taste, soy flour is added and zinc oxide ZnO is improved to improve the hygroscopic properties.
