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.
