Abstract

A Chinese-medicinal additive of feed for promoting growth of animal, increasing the conversion rate of feed and preventing diseases is prepared from coptis root, astragalus root and tangerine peel through extracting, concentrating and spray drying.

Description

Technical field: [0001] The invention relates to a feed additive, in particular to a compound Chinese herbal medicine feed additive composed of multi-taste Chinese herbal medicines. [0002] The invention also relates to a preparation method of the Chinese herbal medicine feed additive. Background technique: [0003] The existing feed additives for disease resistance and growth promotion are mainly antibiotics and chemical drug additives, and some Chinese herbal medicine additives are also useful. The disadvantage of antibiotics and chemical drug additives is that long-term use has great side effects. On the one hand, it will cause pathogenic microorganisms to develop drug resistance and reduce the effect of animal disease prevention; on the other hand, it will produce drug residues in meat, eggs, milk and the environment, thus Serious threat to human health. For this reason, many countries in the world have restricted and phased out or banned the application of antibiotic...
