The invention discloses a production method for a feed through solid fermentation of soy sauce residues by Aspergillus niger. The method comprises the following steps: inoculating an Aspergillus niger strain taken from the inclined plane of a slant PDA solid medium to a PDA liquid medium, shaking up the PDA liquid medium, then carrying out cultivation for 24 h in a mildew incubator with a temperature of 28 DEG C and humidity of 70%, then inoculating 5% of obtained primary Aspergillus niger seeds into the PDA liquid medium and carrying out cultivation for 36 h under the conditions of a temperature of 29 DEG C and a speed of 180 r/min so as to obtain secondary Aspergillus niger seeds; and mixing 5% of soy sauce residues with water content of 80% with secondary Aspergillus niger seed liquid and carrying out cultivation for 72 h at a temperature of 25 to 30 DEG C so as to prepare the feed. According to the invention, Aspergillus niger is used for solid fermentation of the soy sauce residues, so crude protein content is increased by 56.8%, coarse fiber content is decreased by 68%, and the prepared feed can be easily absorbed by livestock and poultry and has improved palatability and an enhanced utilization rate.
