USE - The feed is useful for promoting the growth of pig.    ADVANTAGE - The feed can be economically prepared with rich taste in an environmentally-friendly manner.    DETAILED DESCRIPTION - Pig feed comprises: herbs; 550-600 pts. wt. corn oil; 100-110 pts. wt. bran; 200-220 pts. wt. rice paper pith; 1-2 pts. wt. grass; 1-2 pts. wt. motherwort; 1-2 pts. wt. Akebia; 30-40 pts. wt. shrimp; 1-2 pts. wt. purple flour; 3-4 pts. wt. dandelion powder; 4-5 pts. wt. dibasic calcium phosphate; 4-5 pts. wt. peel; 2-3 pts. wt. trace elements; 3-4 pts. wt. amino acid; 3-4 pts. wt. palm oil; 7-10 pts. wt. black wolfberry; 4-5 pts. wt. Lactic acid bacteria; and 5-6 pts. wt. additives. The additives are prepared by mixing oyster shell and corn germ flour with strawberry juice, cooking the oyster shell with the corn oil using a frying pan, adding chopped chicken skin and water to the fried material, then soaking in jujube, silk seeds, Lotus stem, grass and fenugreek, mixing sunflower stem pith and peach gum with each other, gently heating the mixed mixture for 3-5 minutes under stirring, then mixing with buckwheat flour and other ingredients for 5-10 minutes, and drying and pelletizing the resulting fried mixed material to obtain the additive. An INDEPENDENT CLAIM is included for preparing the pig feed, comprising mixing grass, motherwort, Akebia, shrimp having a length of 1 nm and nano powder with each other, adding hydrological material for 20-30 minutes to obtain a powder, adding water to the corn to form a paste, adding bran oil and cypress, heating the mixture under stirring until the mixture containing ingredients are cooked, mixing the obtained powder with purple flour, dandelion powder and lactic acid at 30-35 degrees C for 45-50 hours, stirring once during every 2-3 hours, grinding the black wolfberry, dibasic calcium phosphate, trace elements and amino acids with water to form a pasty material, mixing the pasty material with palm oil, then spray drying, fermenting the pasty material, mixing the pasty material with remaining ingredients, and drying the mixture using a reactor at a rate of 14 to obtain the feed.
