The invention discloses 
forage for middle pig, and a preparation method thereof. The 
forage is prepared by the following raw materials by weight: 650-660 parts of corn, 220-230 parts of 
soybean meal, 80-90 parts of brans, 100-110 parts of rice 
bran, 3-4 parts of 
zeolite powder, 4-6 parts of 
dandelion, 30-35 parts of pomegranate peel, 20-24 parts of pomegranate leaves, 10-12 parts of radix sileris, 3-6 parts of 
semen boitae, 10-12 parts of radix achyranthis bidentatae, 10-12 parts of caulis spatholobi,3-4 parts of 
polygala root, 5-6 parts of a phagostimulant, 1-2 parts of 
grape wine and 1-2 parts of a 
forage leavening agent. The phagostimulant can improve food-calling capacity of the forage. The raw materials are treated by microorganisms, so that he forage has good 
palatability and strong food-calling capacity, can increase 
ingestion speed and 
food consumption of the pig, and solves the problems of 
anorexia and apastia which are caused by forage change and 
climate variation. 
Dandelion added in the formula can clear heat and remove 
toxicity, so that 
disease resistance of the pig is enhanced and the pig does not get sick in a growing period; and radix sileris can increase 
immunity of the pig, improve in-vivo healthy environment of the pig and enhance the 
immunity.
