Example Embodiment

[0016] Example 1:

[0017] A preparation method of fermented brewer's grain used to partially replace soybean meal in meat goose feed includes the following steps:

[0018] (1) Test preparation:

[0019] Source of Bacillus subtilis: Culture Collection Center of Institute of Microbiology, Chinese Academy of Sciences, Bacillus subtilis subsp. subtilis, AS1.2163; Source of Yeast: Culture Collection Center of Institute of Microbiology, Chinese Academy of Sciences, Saccharomyces cerevisiae, AS2.3875.

[0020] Weigh 18.0 g of nutrient broth, heat it and dissolve it in 1000 mL of distilled water, with a pH of 7, dispense each 100 mL in a triangular flask, and autoclave at 121°C for 25 minutes for use.

[0021] Turn on the UV lamp of the ultra-clean workbench for 30 minutes, then turn on the fan to blow for 10 minutes; wait until the temperature of the bacterial solution returns to room temperature for inoculation; pick a loop of Bacillus subtilis in the ultra-clean workbench and inoculate it ...

Example Embodiment

[0029] Example 2:

[0030] A preparation method of fermented brewer's grain used to partially replace soybean meal in meat goose feed includes the following steps:

[0031] (1) Preparation of fermentation medium: Weigh 2.5 kg of brewer’s grains, 1.2 kg of corn flour, 0.8 kg of bran, and 2.4 kg of distilled water. Then add 0.016 kg of brown sugar, 0.024 kg of beef extract, and 0.008 kg of ammonium sulfate to supplement the nutritional deficiency , And mix them evenly;

[0032] (2) Inoculation: Add Bacillus subtilis broth (2.8×10 8 CFU / mL) and activated Saccharomyces cerevisiae (1.3×10 9 CFU / g), the inoculum amount is 16mL / 100g and 12g / 100g respectively, then mix well, put it in a sealed container, and incubate at 32°C for 10 days.

Abstract

The invention relates to fermentation brewer grains for partially replacing bean pulp in a broiler geese feed. The fermentation medium is prepared from the following raw materials in parts by weight: 2.5-3.5 parts of brewer grains, 0.8-1.2 parts of corn flour, 0.8-1.2 parts of bran, 1.6-2.4 parts of distilled water, 0.016-0.024 part of brown sugar, 0.016-0.024 part of beef extract and 0.008-0.012 part of ammonium sulfate. The fermentation is wide in raw material variety source, sufficient in nutrition and high in digestion utilization, can be used for improving the palatability of the feed, degrading anti-nutrition factors and harmful components in the raw materials and regulating the microecological balance of animal intestines, so that the application range of the brewer grains is enlarged, the culturing cost is reduced, and the foundation is laid for improving the resource utilization of the brewer grains.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to fermented brewer's grains for partially replacing soybean meal in meat goose feed. Background technique [0002] For a long time, my country has mainly used soybean meal as protein feed raw material. Affected by various domestic and foreign factors, the price of soybean meal has fluctuated irregularly, which has brought huge pressure and risks to the operation of breeding enterprises. Therefore, the development of new protein raw material resources is a must. It is an important way to reduce the cost of breeding and stabilize the price of protein raw materials. However, miscellaneous meal contains toxins and anti-nutritional factors, which affects its application in feed. Therefore, research and exploration to reduce or eliminate anti-nutritional factors of miscellaneous meal in order to improve the quality of feed grains is an important way to alleviate the shortage of f...
