The invention relates to a cattle and sheep fattening barbary wolfberry fruit and licorice root health-care licking brick and a preparation method thereof, and the licking brick is characterized in that each kg of the licking brick comprises the following raw materials: 0.21-0.35g of ferrous sulfate, 0.21-0.35g of zinc sulfate, 0.14-0.21g of copper sulfate, 0.24-0.35g of manganese sulfate, 0.01-0.02g of sodium selenite, 0.07-0.35g of potassium iodide, 0.03-0.07g of cobalt chloride, 0.14-0.35g of magnesium oxide, 6.0224-8.038g of chromium nicotinate, 30-150g of sodium sulfate, 200-300g of common salt, 200-300g of bentonite, 30-60g of molasses, 190-285g of barbary wolfberry fruit and 50-100g of licorice root. The preparation method combines the chemical coagulation technology and the mechanical pressing technology, simultaneously targets the characteristics of cattle and sheep fattening and develops the nutrition licking brick which adds the barbary wolfberry fruit and the licorice root and supplements cattle and sheep complex nutrition, thereby fully playing good properties of cattle and sheep. The licking brick is characterized by a wide range of sources for selecting a curing agent, low cost, more comprehensive nutrition, greater density, reasonable feed intake, sustained release of elements, health care, safety, environmental protection and the like, thereby being suitable for raising levels with different feeding methods.
