NOVELTY - Preparation of premixed woody feed comprises preparing pure environment-friendly broad-spectrum antibacterial feed additive by preparing graphene suspension, preparing Paulownia flower extract, and adding graphene suspension to Paulownia flower extract; adding antibacterial feed additive to crushed woody feed, and uniformly mixing with other additives including salt, calcium powder, trace elements, amino acids and vitamins; and granulating and drying. The weight ratio of antibacterial feed additive, crushed woody feed and other additives is 0.1-0.4:100:0.15-0.6. USE - Method for preparing premixed woody feed. ADVANTAGE - The premixed woody feed replaces antibiotic with Paulownia flower extract. Compared with chemical synthesized antibiotic, the Paulownia flower extract is natural and environment-friendly plant-derived antibacterial which is safe to human and animals, eliminates antibiotic residues in livestock, and ensures health of people and promotes food safety.
