Fermented soft pellet feed for Pacific white shrimp and preparation method and application thereof

The invention provides fermented soft pellet feed for Pacific white shrimp and a preparation method and application thereof. The feed is prepared from the components: 40-50 kg/ton of solid fermentation complex enzyme of Aspergillus niger, 1-1.5 kg/ton of bacillus coagulans powder, 400-600kg/ton of fermented wet feed, 10-20kg/ton of a binder and 400-450kg/ton of high-gluten flour. According to thesoft pellet feed, low temperature pelletizing is performed on lactic acid bacteria and yeast fermentation broth-fermented wet feet and the solid fermentation complex enzyme and the bacillus coagulanspowder, and soft pellets which can be directly ingested by shrimps can be made through the action of the binder; the combination of the lactic acid bacteria and yeast suppresses the mildewing of the soft pellets; and the feed is mainly used in the culture of Pacific white shrimp, and is of great significance for improving production performance, reducing food coefficient, and improving the water environment of culture. 本发明
