Fermented soybean meal for piglets and preparation method of fermented soybean meal

Abstract

The invention relates to fermented soybean meal for piglets and a preparation method of the fermented soybean meal. The preparation method comprises the following steps of taking the following components in parts by weight of 100 parts of soybean meal, 30-50 parts of water, 0.1-0.5 part of aspergillus oryzae spore powder and 1-10 parts of bacillus seed liquid, performing uniform mixing, and performing solid-state aerobic fermentation so as to obtain solid-state aerobic fermentation substances; taking the following components in parts by weight of 100 parts of the solid-state aerobic fermentation substances, 1-5 parts of lactobacillus acidophilus seed liquid, 1-5 parts of enterococcus faecalis seed liquid, 1-5 parts of microzyme seed liquid, 1-10 parts of clostridium butyricum seed liquid and 20-50 parts of water, performing uniform mixing, and performing solid-state anaerobic fermentation so as to obtain solid-state anaerobic fermentation substances; and pressing the solid-state anaerobic fermentation substances into slice-shaped substances. Through two-step fermentation, the fermentation time is shortened, bad nutrition factors in the soybean meal are sufficiently degraded, the content of free amino acids in fermentation products is increased, and the problem that materials are difficult to bake is solved. Through low-temperature baking, the activity of small peptide, amino acids and immunocompetence substances is reserved.

Description

technical field [0001] The invention belongs to the technical field of fermented soybean meal, and in particular relates to a fermented soybean meal for piglets and a preparation method thereof. Background technique [0002] For piglets, since various functions are not perfect, there are few digestive enzymes in the gastrointestinal tract, and plant protein cannot be used. Weaning is the biggest stress faced by piglets after birth. Feed changes and a series of environmental stresses eventually lead to negative weight gain, diarrhea and even death of piglets within one week of weaning. Therefore, how to increase the daily weight gain of weaned piglets and reduce piglet diarrhea and mortality is an important way to improve piglet production performance. Antibiotics are often used in production to control piglet diarrhea, but excessive use of antibiotics will lead to immunosuppression of piglets, growth retardation in the later stage, and excessive use of antibiotics will prod...
