The invention discloses a piglet compound feed composition with fermented rapeseed meal. The piglet compound feed composition contains the following raw material components in percentage by weight: 40%-60% of corns, 8%-15% of puffed corns, 3%-5% of bran, 1%-3% of freshwater fish meal, 15%-20% of bean pulp, 5%-10% of fermented rapeseed meal, 0.2%-0.5% of dicalcium phosphate, 0.5%-1% of limestone powder, 0.1%-0.3% of 98% lysine, 0.01%-0.03% of methionine, 0.05%-0.1% of choline chloride, 0.2%-0.5% of salt, and 1%-1.5% of premixes. The compound feed disclosed by the invention is based on a normal corn and bean pulp piglet feedstuff formula, and adopts the fermented rapeseed meal to replace equivalent 8% bean pulp to supplement part of artificially synthesized amino acid; and partial bean pulp is replaced by the fermented rapeseed meal, the pig production performance is not affected, and the weight gaining cost of pork pigs is lowered at the same time.
