Embodiment 1

[0036] The preparation method of the fermented feed using bean dregs and rice bran as main raw materials comprises the following steps:

[0037] (1) Preparing a compound enzyme preparation: mixing cellulase, pectinase, papain, and neutral protease in a mass ratio of 1:1:0.5:0.5 to obtain a compound enzyme preparation;

[0038] (2) Preparation of compound enzyme preparation liquid: the compound enzyme preparation and water are mixed in a mass ratio of 1:5 to obtain a compound enzyme preparation liquid;

[0039] (3) Prepare bean curd residue dehydration: dehydrate fresh bean curd residue until the moisture content of bean curd residue is 72%;

[0040] (4) Enzymolysis of bean curd residues: mix bean curd residues and compound enzyme preparation solution at a mass ratio of 1000:0.5, and carry out enzymatic hydrolysis at 50° C. for 0.5 h to obtain enzymatically hydrolyzed bean curd residues;

[0041] (5) Mix the bean curd residue after enzymolysis with fresh full-fat rice bran in ...

Embodiment 2

[0046] The preparation method of the fermented feed using bean dregs and rice bran as main raw materials comprises the following steps:

[0047] (1) Preparing a compound enzyme preparation: mixing cellulase, pectinase, papain, and neutral protease in a mass ratio of 1:1:0.5:0.5 to obtain a compound enzyme preparation;

[0048] (2) Preparation of compound enzyme preparation liquid: the compound enzyme preparation and water are mixed in a mass ratio of 1:5 to obtain a compound enzyme preparation liquid;

[0049] (3) Prepare bean curd residue dehydration: dehydrate fresh bean curd residue until the moisture content of bean curd residue is 70%;

[0050] (4) Enzymolysis of bean curd residues: mix bean curd residues and compound enzyme preparation solution at a mass ratio of 1000:0.5, and carry out enzymatic hydrolysis at 50° C. for 0.5 h to obtain enzymatically hydrolyzed bean curd residues;

[0051] (5) Mix the bean curd residue after enzymolysis with fresh full-fat rice bran in a ...

Embodiment 3

[0056] The fermented feed prepared by Example 1 or 2 of the present invention was additionally added with 5% feed for lactating sows, and the test results are shown in Table 1:

[0057] Table 1

[0058]

[0059]

[0060] Experiments show that the fermented feed prepared by the invention has obvious effects in feed for lactating sows, the average feed intake is increased by 0.33kg / head, and the lactation volume is increased by 8.63kg / head. The rich GABA improves the sow's immunity, reduces the sow's stress response, and the acid-soluble protein is easy to absorb, and the comprehensive effect promotes the increase of milk production. The rich dietary fiber and microbial metabolites in the fermented feed can significantly improve the constipation problem of sows.

Abstract

The invention discloses a preparation method of fermentation feed by taking bean dregs and rice bran as major raw materials. The preparation method comprises the steps of preparation of a composite enzyme preparation, preparation of a composite enzyme preparation solution, dehydration preparation of the bean dregs, enzymolysis of the bean dregs, mixing of the bean dregs and the fresh full cream rice bran, mixing of active dry yeast and pediococcus pentosaceus freeze-drying powder, mixing of water and a mixed inoculant, mixing of the mixed raw materials and a fermentation solution, and anaerobic fermentation. The feed prepared by the method has high contents of acid soluble protein, lactic acid bacterium and gamma aminobutyric acid and has the characteristics of long shelf life, good stability and the like.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feed, and in particular relates to a preparation method of fermented feed using bean dregs and rice bran as main raw materials. Background technique [0002] A lot of bean curd dregs will be produced in the soybean product industry, and the dry matter accounts for about 10-15%. In dry matter, protein accounts for 25-28%, fat accounts for 12-15%, dietary fiber and polysaccharides account for about 45-60%, and contains a lot of minerals and trace elements. As a by-product, because of its low price and high cost performance, it is a very high-quality feed raw material. [0003] There are two reasons why bean curd residue cannot be widely used: [0004] On the one hand, since bean curd dregs contain a large amount of anti-nutritional factors, direct feeding will affect the health of pigs, resulting in loose stools and inability to efficiently absorb nutrients. Some heat-sensitive anti...
