The invention relates to a method for preparing a fast-fattening pig additive. The additive comprises the following materials by weight percentage: 10 to 20 percent of
bone meal, 8 to 13 percent of medicated leaven, 8 to 13 percent of
fish meal, 8 to 13 percent of radix astragali, 8 to 13 percent of radix-polygoni multiflori, 8 to 13 percent of asket
fern, 1 to 2 percent of non-iodized salt, 3 to 5 percent of
Jian leaven, 4 to 10 percent of pine needle
meal, 3 to 6 percent of rhizoma atractylodis, 3 to 6 percent of dried old orange peel, 3 to 5 percent of shelled cedar seed, 3 to 5 percent of wild
chrysanthemum flower, 1 to 2 percent of radix stemonae, and 1 to 2 percent of asiatic plantain. The method comprises the following steps: taking the
bone meal, the medicated leaven, the
fish meal, the radix astragali, the radix-polygoni multiflori, the asket
fern, the non-iodized salt, the
Jian leaven, the pine needle
meal, the rhizoma atractylodis, the dried old orange peel, the shelled cedar seed, the wild
chrysanthemum flower, the radix stemonae and the asiatic plantain in proportion, and putting all the materials into a
drying machine, wherein the temperature in the
drying machine is controlled to be between 30 and 50 DEG C, the
drying time is between 30 and 40 minutes, and the
dryness of the dried materials is controlled to be between 85 and 95 percent; taking out the materials and crushing the same into
powder in a
crusher; and taking out the
powder and putting the
powder into a container for standby.
