The invention discloses a wheat middling-corn compound feed for weaned pigs. The wheat middling-corn compound feed comprises the following components in part by weight: 15-17 parts of corn, 8-10 parts of broken rice, 45-50 parts of wheat middling, 4-4.5 parts of biscuit powder, 5-6 parts of wheat bran, 8-10 parts of soybean meal, 2-2.5 parts of chocolate, 1-2 parts of fish powder, and 0.15-0.2 part of composite microorganism bacterium agent, wherein the composite microorganism bacterium agent comprises one or more of enterococcus, saccharomycete and bacillus. The compound feed reduces the content of the corn and the soybean pump by using the wheat middling as a substitute, so that the production cost of the feed is greatly reduced. The wheat-middling compound feed further contains composite microorganism bacterium agent, so that the weaned pigs can well digest the wheat middling, and the nutritions needed for the growth and development of the weaned pigs are completely satisfied; the growth performance is remarkably improved relative to the corn-soybean pulp daily ration; moreover, diarrhea incidence rate is not improved, but reduced, thereby providing a good basis for post high-speed growth of the weaned pigs.
