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.
