The invention relates to the technical field of microorganisms, and in particular relates to a bacillus strain Bacillus subtilis W2Z as well as application and a feed thereof. The bacillus is preserved in the Guangdong Microbial Culture Collection Center in October 2023, and the preservation number of the bacillus is GDMCC (China General Microbiological Culture Collection Center) No.63868. The invention further discloses a preparation method of the bacillus. According to the present invention, the Bacillus subtilis Bacillus sp. W2Z has strong digestive enzyme production activity; the bacterial strain has a relatively strong bacteriostatic effect on aeromonas hydrophila; when the strain is used as a probiotic additive of cherax quadricarinatus feed, the growth performance of cherax quadricarinatus can be improved, and the digestion function, the immunity and the disease resistance to aeromonas hydrophila can be improved, so that the bacillus has great value in development and application of green feed additive
