The invention provides a method for preparing a formula feed for 
broiler chicken in the early stage. The formula feed is prepared from the following raw materials in parts by weight: 50-58 percent of corn, 8-12 percent of 
bran, 25-28 percent of 
soybean meal, 1-3 percent of DDGS, 0.5-1 percent of 
plant oil, 1-1.5 percent of shell 
powder, 0.3-0.6 percent of edible salt and 4-6 percent of mixed batch, wherein the mixed batch comprises 
astragalus membranaceus, lonicera 
japonica, 
hypericum monogynum, 
coptis chinensis, fructus forsythiae, 
radix isatidis, 
cyrtomium fortunei, pine needle 
meal, 
codonopsis pilosula and licorice root. The method comprises the following steps of conducting 
superfine grinding on the traditional Chinese medicinal materials, and adding an 
ethanol solution to the mixture; boiling the mixture with strong fire, conducting insulation with 
slow fire, conducting cooling and filtering, and concentrating the filtrate; adding white granulated 
sugar, and conducting boiling, cooling the mixture to a normal temperature, and inoculating 
lactobacillus, tea 
fungus and 
bifidobacterium; conducting 
fermentation for 96-120 hours until white fungal 
mass grows out, concentrating and 
drying the bacterial liquid at a low temperature, conducting embedding, and conducting 
granulation and cooling at a high temperature to prepare a granular feed which is the formula feed for 
broiler chicken in the early stage. The formula feed can be used for supplying amino acids and trace elements for growth of 
broiler chicken, has the effects of increasing the number of effective microbial communities in intestinal tracts, improving 
immunity, enhancing 
disease resistance of chicken bodies and promoting healthy growth of broiler chicken, and has the advantages of high content of viable organisms and no residue.
