Example Embodiment

[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 Xin Nandu Feed Technology Co., Ltd. Glucose (food grade), KH 2 PO 4 , K 2 HPO 4 , Purchased from Guangzhou Zixinghua Glass Instrument Co., Ltd. The purchased fermented soybean meal is in the form of low-temperature drying and crushing, and the fermentation strains are yeast, Bacillus subtilis, Lactobacillus plantarum and Lactobacillus acidophilus.

[0023] Saccharomyces cerevisiae CNCM I-1079, purchased from Angel Yeast Co., Ltd.; Lactobacillus plantarum CGMCC1258 (LP), Lactobacillus reuteri LR1, which are animals of Guangdong Academy of Agricultural Sciences Preserved by the Pig Nutrition and Feed Laboratory of the Institute of Science...

Example Embodiment

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

[0064] The inventor found that fermented soybean meal with probiotics can not only improve the nutrient content of soybean meal, but also obtain a variety of probiotics. If fed to weaned piglets in a wet state, fermented soybean meal and probiotics may work together in piglets. effect. Therefore, in this example, the fermented soybean meal prepared in the early stage was added to the weaned piglet's diet in a wet state to explore the effect of fermented soybean meal instead of soybean meal on the growth performance, blood indicators, diarrhea rate and intestinal health of the weaned piglet. The effect of adding homemade fermented soybean meal, adding purchased fermented soybean meal 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...
