Embodiment 1

[0020] Example 1 Effect of solid-state fermentation on the nutritional value of soybean meal

[0021] 1.1 Fermentation raw materials

[0022] Soybean meal (20 mesh), soybean hulls, purchased from Nansha Zhizhiyuan Oil Industry Co., Ltd.; acid protease (500000U / g), neutral protease (100000U / g), alkaline protease (200000U / g), purchased from Guangdong New Nandu Feed Technology Co., Ltd. Glucose (food grade), KH 2 PO 4 、K 2 HPO 4 , purchased from Guangzhou Zixing Huabo Instrument Co., Ltd. The purchased fermented soybean meal is in the form of low-temperature drying and crushing. The fermentation bacteria are yeast, Bacillus subtilis, Lactobacillus plantarum and acidophilus lactic acid bacteria.

[0023] Saccharomyces cerevisiae CNCM I-1079 was purchased from Angel Yeast Co., Ltd.; Lactobacillus plantarum CGMCC1258 (LP) and Lactobacillus reuteri LR1 were purchased from Guangdong Academy of Agricultural Sciences. Preserved in Pig Nutrition and Feed Laboratory of Scientific R...

Embodiment 2

[0063] Example 2 Effect of solid-state fermentation on the effect of feeding soybean meal to piglets

[0064] The inventors found that after fermenting soybean meal with probiotics, not only can the nutritional content of soybean meal be improved, but also a variety of probiotics can be obtained. If weaned piglets are fed in a wet form, fermented soybean meal and probiotics may be synergistically developed in piglets effect. Therefore, in this example, the fermented soybean meal produced in the previous stage was added to the diet of weaned piglets in a wet state to explore the effects of fermented soybean meal instead of soybean meal on the growth performance, blood indicators, diarrhea rate and intestinal health of weaned piglets. Effects of adding homemade fermented soybean meal, adding fermented soybean meal purchased from outside and adding probiotics on weaned piglets.

Abstract

The invention discloses a preparation method of fermented soybean meal. The method includes the steps that with soybean meal and soybean hulls as fermentation substrates, a mixed liquor of fermentation strains is added, aerobic fermentation and anaerobic fermentation are carried out in sequence, and then the fermented soybean meal is obtained, wherein the strains include saccharomycetes, bacillussubtilis, lactobacillus plantarum and lactobacillus reuteri. The viable count of the fermented soybean meal prepared by the method is 1000 times that of purchased fermented soybean meal, and a large quantity of lactobacillus and saccharomycetes survive; by feeding piglets with the fermented soybean meal prepared by method, the weight of the piglets is significantly increased compared with that ofpiglets fed with purchased fermented soybean meal.

Description

technical field [0001] The invention relates to the technical field of soybean meal fermentation, in particular to a method for preparing fermented soybean meal. Background technique [0002] The digestive and absorption organs of piglets are underdeveloped, the secretion of gastric acid is insufficient, and the enzyme activity in the body is low. Therefore, early weaning is prone to symptoms such as poor appetite, low feed utilization, slow growth, and decreased disease resistance. In addition, weaning stress and dietary changes It is easy to damage the intestinal structure of piglets and aggravate the above symptoms. Soybean meal has a high protein content, and its amino acid ratio is similar to that of the ideal protein model. It is an important source of dietary protein for piglets. However, weaned piglets have poor digestibility of macromolecular proteins in soybean meal and are sensitive to anti-nutritional factors in it, which greatly limits The application of soybea...
