摘要

Composition resistant to rumen in pills with controlled release of physiologically active substances in the post-ruminal zone of ruminants, comprising: i) a core comprising: - one or more physiologically active substances selected from the group consisting of: amino acids, vitamins , enzymes, proteins, carbohydrates, probiotic microorganisms, prebiotic foods, mineral salts, choline and its derivatives and organic acids; and - a matrix comprising a carnauba wax and / or a microcrystalline wax, ii) a first core coating layer comprising a first hydrophobic substance selected from the group consisting of: fats, fatty acids, hydrogenated oils, mono and bi-glycerides of fatty acids, esters of fatty acids, fatty alcohols, with chains of 12 to 22 carbon atoms and a melting point between 40 and 74 ° C; iii) a second coating layer of said first layer comprising a second hydrophobic substance selected from the group consisting of: microcrystalline waxes, paraffin waxes, vegetable waxes and synthetic waxes with a melting point between 80 and 100 ° C.
