The invention discloses a feed additive containing a traditional Chinese medicine active probiotic culture medium and used for preventing and treating avian influenza. A medium containing traditionalChinese medicine and active probiotics is adopted to carry out fermental cultivation on microorganisms used in a poultry micro-ecological feed additive. The medium containing the traditional Chinese medicine and the active probiotics comprises the following components: wheat bran, corn flour, brown sugar, a traditional Chinese medicine component, light calcium carbonate and yeast extract. The traditional Chinese medicine component comprises codonopsis roots, milk-vetch roots, Chinese magnoliavine fruits, manyprickle acanthopanax roots, baical skullcap roots, Chinese pulsatilla roots, honeysuckles, common andrographis herb, coptis roots, isatis roots, pollen and Chinese thorowax roots. The invention can solve the problems in the prior art that microorganisms in poultry micro-ecological feedadditives are low in amount, low in activity and weak in colonization ability when in intestinal tracts, so that the number of the microorganisms in the poultry micro-ecological feed additives is increased, and the activity of the microorganisms is improved, and the colonization ability of the microorganisms in the intestinal tracts is improved, and further, the avian influenza can be effectivelyprevented and treated.
