The invention belongs to the technical field of animal feed, and particularly relates to a high biological activity feed additive and a preparation method thereof. A highly biologically active feed additive, in parts by weight, comprising 100 parts of biologically active material, 400-1000 parts of a carrier, 30-100 parts of edible oil, 4-20 parts of a binder, and the particle size of the carrier is 20-100 parts. 150um, the thermal conductivity of the carrier is less than or equal to 0.085w/m·k (25°C), and the animal feed with this high biological activity feed additive reasonably added can effectively improve the absorption effect of the nutrient components in the feed by the farmed animals, and improve the animal feed of the farmed animals. Growth rate and disease resistance. |
