Novel eucommia feed additive and production method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a novel feed additive of plant extracts, and provides a novel feed additive using the extract of leaves of Eucommia ulmoides as a raw material and a production method thereof. Background technique [0002] Feed additives are key edible substances added to feed to increase animal physical fitness, improve animal immunity, accelerate growth, increase feed conversion rate, improve animal product quality, and reduce feeding costs. It is the core technology and product of the feed industry. However, the variety structure of domestic feed additives is unreasonable. The output of the four major categories is 745,000 tons of amino acids, 625,000 tons of vitamins, and 97,000 tons of antibiotics. The output of plant extract feed additives is about 2,000 tons. There are very few products, which are far from meeting market demand. [0003] Feed safety is the foundation of animal food safety. With the transformation of my country's animal...

Problems solved by technology

However, most of the existing eucommia feeds are directly added to the feed by crushing eucommia leaves or bark, which is not conducive to the full absorption of the active ingredients of eucommia
