Method using composite bacterium to ferment bean dregs to manufacture protein feed

Abstract

The invention provides a method using a composite bacterium to ferment bean dregs to manufacture protein feed. The composite bacterium is composed of trichoderma, aspergillus oryzae and saccharomyces cerevisiae. Agriculture residues or food residues of a bean dreg class are added to base materials, and composite fermentation is carried out. Products after being fermented are rich in single-cell protein, digestible energy and metabolic energy of the products are improved, the content of rough fibers is reduced, and a great amount of probiotics, abundant enzymes and bioactivator are included. Through detection to unfermented essential nutrients and fermented essential nutrients, compared with the content of bean dreg protein of unfermented bean dregs, the fact that the content of bean dreg protein of bean dregs after being fermented is increased by about 8%, amino acid nitrogen is increased by 4.9 times, the activity of proteinase containing is 1157 U/g, and the bean dregs after being fermented are ideal protein feed.

Description

technical field [0001] The invention relates to a method for making protein feed by fermenting soybean product waste with compound strains. The fermented feed contains various probiotics and biological enzymes that are beneficial to the digestion and absorption capacity of livestock and poultry, and improve immunity and cold stress resistance. and bioactive substances, belonging to the technical field of agricultural products. Background technique [0002] China is the hometown of soybeans and also the birthplace of soybean products. Soybean is one of the important grain and oil crops in my country, with an annual output of more than 10 million, one-third of which is used as the staple food and non-staple food of the people. So far, Chinese-style bean products have a production history of more than 2,000 years. As the nutritional value of soybean products is more and more recognized by people, the upsurge of eating soybean products has swept the world. An economist predic...

Problems solved by technology

At present, when manufacturers and workshops at home and abroad are producing bean products, because raw bean dregs are not easy to preserve and are easy to mold and deteriorate, most of them are directly used as feed, and the utilization rate of their nutrients and energy is less than 20%, which loses its potential. nutritional and economic value

Even if this part of bean dregs is directly used as feed, there are still the following problems: raw bean dregs contain anti-nutritional factors such as antitrypsin, saponin, and hemagglutinin, among which trypsin inhibitors can hinder the action of trypsin in pigs on soybeans. Digestion and absorption of protein-like, causing diarrhea, affecting growth, poor palatability, difficult to digest, low feed titer

Even after simple cooking, these harmful factors still exist. There is a saying "feed bean dregs to pigs, the more you feed, the more you shrink". This is not only a great economic loss, but also a great waste of precious resources. Therefore, How to make full use of the increasing production of bean dregs and other bean product waste has become one of the concerns of scientific researchers in various countries
