[0035] Example 1
[0036] The method for preparing fermented feed using bean dregs and rice bran as main raw materials includes the following steps:
[0037] (1) Preparation of composite enzyme preparation: mixing cellulase, pectinase, papain, and neutral protease in a mass ratio of 1:1:0.5:0.5 to obtain a composite enzyme preparation;
[0038] (2) Preparation of composite enzyme preparation solution: Mix the composite enzyme preparation with water at a mass ratio of 1:5 to obtain a composite enzyme preparation solution;
[0039] (3) Dehydrating the tofu residue: dehydrating the fresh tofu residue to a moisture content of 72%;
[0040] (4) Enzymatic hydrolysis of bean curd dregs: Mix bean curd dregs with the compound enzyme preparation solution at a mass ratio of 1000:0.5, and perform enzymatic hydrolysis at 50°C for 0.5 hours to obtain enzymatically hydrolyzed bean curd dregs;
[0041] (5) Mix the enzymatically hydrolyzed bean curd residue with fresh whole-fat rice bran at a mass ratio ...

[0055] Example 3
[0056] The fermented feed prepared in Example 1 or 2 of the present invention was supplemented with 5% of lactating sow feed. The test results are shown in Table 1:
[0057] Table 1
[0058]
[0059]
[0060] Experiments show that the fermented feed prepared by the present invention has obvious effects in lactating sow feed, the average feed intake is increased by 0.33 kg / head, and the lactation volume is increased by 8.63 kg / head. The abundance of γ-aminobutyric acid enhances the sow’s immunity and reduces the sow’s stress response. The acid-soluble protein is easily absorbed, and the comprehensive effect promotes the increase in lactation. The rich dietary fiber and microbial metabolites in fermented feed significantly improve the constipation of sows.
