The invention relates to fodder and a use method, in particular to concentrated calf fodder and a use method thereof. The fodder comprises protein fodder and a premix compound, wherein the protein fodder is prepared from raw materials of bean cakes, corn protein powder, cotton dregs, complex enzymes, and the like; and the premix compound is prepared from common salt, fluorspar powder, magnesium sulfate, sodium diacetate, calcium hydrogen phosphate, soda, sodium humate, monensin, vitamins and trace elements of copper, iron, manganese, zinc, cobalt, and the like. The use method comprises the following steps: manually feeding calves at age of 3-5 days with a mixture of the concentrated calf fodder and a certain amount of milk; and stopping feeding the milk when the calves are at age of 60 days; and coming into a fatting period when the calves are at age of 120 days. The calf fodder has complete nutrients, reasonable proportion and low cost and is fed to the calves in a suckling period to substitute a great amount of milk, improve the commodity rate of the milk, facilitate the growth and the development of the calves, shorten the suckling period by 50 percent, increase the weight-gaining speed by about two times, shorten the deliver time by one half, increase the current fertility rate of milk cows by about two times, realize perennial milking, facilitate mechanical milking and scaled stabling management and remarkably improve the economic benefits, the social benefits and ecological benefits of cattle rearing in a plurality of aspects.
