The invention provides a novel eucommia feed additive and a production method thereof. The production method comprises the steps of adding water into dried eucommia leaves, performing extraction under 50-60 DEG C for 4-6 hours, and pumping leach liquor into a storage tank; then adding water for secondary leaching, and combining the leach liquor; adding a natural clarifying agent into the leach liquor, stirring for 30 minutes, and stewing for one night for precipitation; extracting supernate into a vacuum concentrator, separating lower suspension through a tubular centrifugal machine, combining filtrate and supernate, performing vacuum concentration under 60 DEG C, and controlling the baume degree of a concentrated solution to be 28-32; atomizing the concentrated solution under the temperature of 170-180 DEG C to instantly dry the particles to form the novel eucommia feed additive. Contents of effective components such as chlorogenic acid, eucommia ulmoides oliv polysaccharides and eucommia ulmoides flavonoids in the novel eucommia feed additive are high; the quality is stable; the novel eucommia feed additive is suitable for healthy breeding for animals such as pigs, livestock, fish and shrimps and has the effects of replacing antibiotic, enhancing the anti-disease immunity of the livestock, reducing the breeding periodic death rate, increasing the feed conversion rate, improving the meat quality, promoting animal growth, reducing ammonia-nitrogen output amount and the like.
