Embodiment 1

[0073] (1) Preparation of brewer's yeast mud seed liquid:

[0074] 1) Inoculate fresh brewer's yeast slurry into a medium made of glucose, corn steep liquor dry powder, zinc sulfate, ferrous sulfate, dipotassium hydrogen phosphate, magnesium sulfate, sodium chloride, manganese sulfate and purified water, and after 48h~ 64h aerated culture to obtain brewer's yeast slime seed liquid;

[0075] 2) Brewer's yeast slime culture medium and culture conditions: Brewer's yeast slime is inoculated to a concentration of 2% to 3% of glucose, 2% to 3% of dry corn steep liquor, 0.1% to 0.2% of zinc sulfate, and 0.1% to 0.1% of ferrous sulfate. 0.2%, dipotassium hydrogen phosphate 0.1% ~ 0.2%, magnesium sulfate 0.1% ~ 0.2%, sodium chloride 0.1% ~ 0.2%, manganese sulfate 0.1% ~ 0.2% of the purified water culture medium, with Sodium hydroxide adjusts the pH value to 5.0-6.0, the inoculum amount of beer yeast slime is 20-30%, at a temperature of 28°C-32°C, after 48-64 hours of aerated culture, ...

Embodiment 2

[0116] The microbe fermented wet feed obtained by using the brewer's yeast mud produced by the present invention is applied in livestock and poultry breeding. Add 5% to 10% of the weight of the diet in piglet feeding to conduct the test, and the test results are shown in Table 1:

[0117] Table 1 The test results of microbial fermented wet feed produced by brewer's yeast mud on piglet weight gain and reduction of diarrhea rate

[0118]

[0119] *Experimental group 1: Diet+10% utilizes the microbial fermented wet feed produced by brewer's yeast mud;

[0120] Test group 2: ration+5% utilizes the microbial fermented wet feed that brewer's yeast mud produces;

[0121] Control group: diet.

[0122] As can be seen from the test results in Table 1, compared with the control group, the daily weight gain rate of piglets increased by 7.52%, and the feed-to-weight ratio decreased by 3.03%; the diarrhea index decreased by 51.8%; the test group 2 was compared with the control group ,...

Embodiment 3

[0128]The microbe fermented wet feed produced by using the brewer's yeast mud obtained in the present invention is applied in livestock and poultry breeding. Add 2% of the diet weight in the diet of sea blue brown shell hens, and the results of the feeding test are shown in Table 3;

[0129] Table 3 Effect of microbial fermented wet feed produced by brewer's yeast mud on the performance of laying hens

[0130]

[0131] Both the test group and the control group had 350 animals. During the test period: 6 animals died in the test group, and 13 animals died in the control group.

[0132] *Test group 1: Diet + 2% microbial fermented wet feed produced by beer yeast mud; Control group: Diet.

[0133] As can be seen from Table 3: in 350 sea-blue brown shell hens, through the 35-day test period, the test group (adding 2% microbial fermented wet feed produced by brewer's yeast mud in the diet) is more effective than the control group (not in the diet). Adding microbial fermented we...

Abstract

The invention discloses a method for producing microbial fermentation wet feed by utilizing beer yeast paste. Bean pulp, corn slurry dry powder, corn germ meal, wheat bran and rice bran serve as solid fermentation raw materials, live yeast in the beer yeast paste serves as a main strain, bacillus subtilis, bacillus licheniformis, lactobacillus acidophilus and lactobacillus plantarum serve as auxiliary strains, and the microbial fermentation wet feed is produced. Beer yeast paste seed solution and seed solution of four bacteria are mixed and added into the solid fermentation raw materials, fully stirred and placed in an anaerobic container to be contained and fermented or placed on a fermentation bed to be stacked and fermented; through the fermentation process for 96-120 h, the mixture directly serves as feed or is dried at a low temperature of 60 DEG C and then smashed to 60 meshes through a pulverizer, and the microbial fermentation wet feed produced by utilizing the beer yeast paste is obtained. The produced microbial fermentation wet feed is simple in production process and low in cost, saves energy, is environmentally friendly and good in product quality, and obviously promotes growth of bred animals.

Description

technical field [0001] The invention relates to the technical field of microbial fermented wet feed. In particular, it relates to a method for producing microbial fermented wet feed by using beer yeast mud. Background technique [0002] In recent years, my country's beer industry has developed rapidly, with annual output increasing at a rate of 10%, reaching 39 million tons in 2013. Brewer's yeast slime is the main by-product of beer production, accounting for about 1.5% of beer production. Beer yeast slime contains 50% to 60% of protein and 8 kinds of essential amino acids for human body. Among them, the content of lysine in amino acids is very high. It can exceed imported fish meal, and also contains a variety of enzymes and yeast. At present, for the comprehensive development and utilization of beer yeast mud, there are the following several ways. [0003] 1. Production and application status of beer yeast slime [0004] 1. Brewer's yeast mud is directly fed as feed ...
