The invention relates to a low-protein feed for child-care later-stage piggies, in particular to the low-protein feed which is low in protein content, and low in additive amount of the soybean meal, for child-care later-stage piggies, and belongs to the field of feeds. The feed consists of the following raw materials in parts by weight of 20-30 parts of puffed corn, 40-50 parts of corn, 10-15 parts of 46% of soybean meal, 4-8 parts of puffed soybeans, 4-8 parts of five-grain peptide, 2-6 parts of fermented soybean meal, 1-2 parts of calcium hydrogen phosphate, 0.4-0.8 part of lysine, 0.3-0.7 part of methionine, 0.5-1 part of threonine, 0.4-0.8 part of an acidulant, 0.2-0.6 part of sodium chloride, 0.1-0.3 part of choline chloride, 0.1-0.3 part of valine, 0.5-1 part of soybean oil, 0.01-0.2part of zinc oxide, 0.1-0.3 part of lysophosphatidylcholine and 1 part of a premix. The low-protein feed is reasonable in formula; and according to the low-protein feed, the use of the soybean meal can be reduced, the low-protein feed can meet requirements of piggies, and under the premise that negative effect does not exist, the problem that the protein raw materials are in lack is solved to a certain extent, and the feed cost is reduced. Besides, the pollution of an aquatic plant to environment is reduced.
