The invention discloses a creep feed. The creep feed is prepared from the following raw materials of puffed corn, corn, flour, puffed soybeans, super steam fish meal, 46% soybean meal, cane sugar, glucose, soybean oil, coconut oil, spray-dried dried egg yolk, yeast nucleotide, nonfat dry milk powder, whey powder, calcium propionate, calcium dihydrogen phosphate, multi-vitamins for piglets, montmorillonite, 98% lydine hydrochloride, DL-solid methionine, 98.5% L-threonine and a creep core material, wherein the creep core material consists of the following raw materials of table salt, composite organic trace elements, enveloping zinc oxide, a blood supplementing agent, a composite acidulant, a composite phagostimulant, a composite enzyme preparation, tryptophan, valine, N-carbamylglutamic acid, 50% choline chloride, an antioxidant, wheat hydrolyzed protein and puffed corn powder. Through adoption of the creep feed, the immune functions of the piglets can be quickly enhanced, generation ofdiseases is reduced, weaning stress is reduced, and food consumption of the piglets is increased. The invention further provides a preparation method of the creep feed. The creep feed is simple in technology and suitable for industrialized production.
