The invention discloses a natural
plant feed additive for promoting healthy development of the
digestive tract of a weaned piglet and a preparing method thereof. The
feed additive consists of the following ingredients in parts by weight: 30 to 50 parts of dried orange peel, 20 to 30 parts of pomegranate peel, 10 to 20 parts of folium isatidis, 10 to 20 parts of hawthorn, 10 to 30 parts of
red rice, 2 to 3 parts of ash barks, 3 to 5 parts of Chinese pulsatilla roots, 3 to 5 parts of golden

red rice are respectively crushed and sieved by a 120-mesh
sieve, and are then uniformly mixed to be made into
fine powder; then, the ash barks, the Chinese pulsatilla roots, the golden
cypress, the angelica, the
astragalus and the
codonopsis pilosula are mixed; water being 2 to 4 times of the weight of raw medical materials is added; the
water extraction is carried out twice; the extraction liquid in the twice is merged for concentration; the concentration liquid is sprayed into
fine powder; hot
air drying is carried out until the
water content is less than 10 percent, and the
feed additive is obtained. The feed additive provided by the invention has the effects of regulating the
spleen and the
stomach of the piglet, obviously improving the
digestive tract function of the piglet, improving the feed intake quantity, preventing the
digestive tract diseases, reducing the occurrence of
