Problems solved by technology

However, the disadvantages of antibiotics as feed additives are also becoming more and more prominent: causing increased drug resistance of pathogenic bacteria; increasing use of antibiotics for feeding, increasing breeding costs, and drug residues are becoming more and more serious; resulting in decreased immunity of livestock and poultry; causing animal stomach Intestinal flora imbalance; antibiotics remain in large quantities in livestock and poultry products and the environment, seriously threatening human health and environmental safety, etc.

Abstract

The invention discloses a plant composite extract for a feed additive, and a preparation method and application thereof. The plant composite extract is the mixture of a material extract A and a peel extract B of citrus fruits, or the mixture of the extract A, the extract B and rice bran, wherein the material extract A contains tea polysaccharide, tea polyphenol and tea saponin; and the peel extract B contains volatile oil and plant polysaccharide. The plant composite extract has the advantages of natural resource, no residue to the environment, no toxic or side effect on livestock and marine animals and good disease-prevention and growth-promotion effect completely identical with that of a feed antibiotic, and is an ideal substitute for the feed antibiotic.

Description

technical field [0001] The invention relates to a feed additive plant compound extract and its preparation method and application, in particular to a feed additive plant compound extract which can replace antibiotics to promote animal growth, its preparation method and application. Background technique [0002] Since the middle of the 20th century, antibiotics have been widely used in aquaculture, and their effects of preventing and treating diseases, promoting nutrient absorption, increasing appetite, and promoting growth and development are generally recognized. Therefore, antibiotics have become the most widely used growth-promoting feed additives. However, the disadvantages of antibiotics as feed additives are also becoming more and more prominent: causing increased drug resistance of pathogenic bacteria; increasing use of antibiotics for feeding, increasing breeding costs, and drug residues are becoming more and more serious; resulting in decreased immunity of livestock ...
