Abstract

The invention discloses a gentian H-containing natural antibiotic feed additive which is an ethanol aqueous solution containing the gentian H, wherein the mass concentration of the gentian H is 0.8 to 1.3 percent, and the mass concentration of ethanol is 0.6 to 0.9 percent. The gentian H-containing natural antibiotic feed additive is applied in poultry animal feed and ruminants. The gentian H contained in the natural antibiotic feed additive disclosed by the invention has an (E)-3,5,4-trihydroxystilbene skeleton structure, belongs to natural edible antibiotic, has anti-drug resistance and safety of natural plant antibiotic, and accords with the trend that feed antibiotic develops towards the direction of high efficiency and low residue; according to the feed additive, scientific application of the feed antibiotic can be ensured, and negative actions and unsafe factors of traditional antibiotic feed additives are effectively reduced; the gentian H-containing natural antibiotic feed additive is broad in application prospect and is huge in market potential.

Description

technical field [0001] The invention belongs to the application field of natural products, and in particular relates to a natural antibiotic feed additive containing gentian H, a preparation method and application thereof. Background technique [0002] Almost all feed producing countries in the world add various antibiotics to feed to improve feed remuneration. It should be said that for nearly half a century, antibiotics have been added to feed as antibacterial growth agents, which have indeed played a positive role in controlling the occurrence of livestock and poultry diseases, promoting the growth and development of livestock and poultry, and improving the economic efficiency of feeding. According to statistics, there are more than 20 kinds of antibiotics and more than 10 kinds of synthetic antibacterial drugs used in feed in the world. The amount of antibiotics used as feed additives is negligible, mostly calculated in parts per million (mg / kg). Even so, the European U...
