Preparation method and application of microorganism feed for milk thistle silybum marianum meal

Abstract

The invention discloses a preparation method and application of a microorganism feed for milk thistle silybum marianum meal. The preparation method comprises the following steps of adding acid protease, cellulases, xylanase, mannase, alpha-galactosidase, beta glucanase and phytase to the milk thistle silybum marianum meal, adding calcium hydrogen phosphate, performing uniform stirring, and performing first-stage fermentation with bacillus and microzymes; and then adding lactic acid bacteria and bifidobacteria, and then performing second-stage anaerobic fermentation in a one-way membrane anaerobic bag to obtain finished products of the microorganism feed. The content of viable bacteria is increased, and the preparation raw materials are free from sterilization. The prepared products are free from drying treatment, and the production cost is reduced. The finished products of the microorganism feed contain rich functional substances of viable bacteria, enzyme groups, vitamins, lipid, organic acid, amino acids, various oligosaccharide and coenzyme factors, small peptide and the like, and are few in infectious microbes and obvious in feeding effects. The utilization efficiency of the feed is improved, the immunity and the resistance of the fed objects are effectively improved, the microorganism feed can be used for replacing antibiotics, the quality of animal products is further improved, the fetor of fence shed is eliminated, and the ecological benefits are obvious.

Description

technical field [0001] The invention relates to the field of feed preparation, in particular to a preparation method and application of milk thistle meal microbial feed. Background technique [0002] At present, the market scale of the feed industry is huge, and it is increasing at a rate of about 15% per year, but the profit is very low. Most of them are produced with grain as raw material, and the cost is difficult to reduce. It will be one of the future development directions to produce cheap and high-quality biological feed through a series of microbial treatments from non-grain raw materials. Microbial feed is an environmentally friendly and safe feed that has become popular in recent years. It is an active feed produced by probiotics as the main fermentation strain. The probiotic effects of feed utilization, health care and many other aspects can completely or partially replace antibiotics.

Problems solved by technology

[0003] Milk thistle meal is the residue after extracting silymarin from traditional Chinese medicine factories. In most cases, it will be discarded and pollute the environment. In some cases, it will be bought at a low price for cattle and sheep farmers, but it is difficult to get better utilization.

In fact, milk thistle meal also contains more than 20% protein, rich in carbohydrates, including more than 20% starch, 30% to 40% crude fiber, especially more than 1% total flavonoid residue, if it is applied to animal The use value of the feed is significant; however, according to most of the current methods, it is directly added to animals in a certain proportion, which has the problems of poor palatability, low digestion and absorption rate, low added value, and insignificant feeding effect

[0004] There are also very few reports on the use of milk thistle meal for the production of microbial feed, such as Chinese invention patent 201210183876.5, which discloses a method for aerobic fermentation after inoculation with Aspergillus niger and Candida tropicalis, and then drying into finished products; but the culture medium Sterilization and drying of fermented finished products will increase the cost, require high equipment, and the activity of bacterial enzymes and functional substances will be greatly reduced after drying, poor palatability, and poor control of inorganic nitrogen residues such as urea will cause single poisoning of stomach animals
