Problems solved by technology

Its disadvantages are: due to differences in regions and climates, the variety and quantity of beneficial microorganisms in nature and the existence of other harmful microorganisms, coupled with the variety, quality and proportion of feed raw materials, the saccharification effect of feed varies widely, and even corruption occurs , leading to a decline in livestock production efficiency or even death, and ultimately making this technology unable to be promoted
Its disadvantages are: because the nutritional ingredients in the formula of the complete feed for livestock and poultry are only suitable for the growth needs of livestock and poultry, it is not suitable for the reproduction of beneficial microorganisms. In addition, there are a large number of E. coli in the raw materials, and the temperature in the bag cannot be controlled. The degree of progress cannot be judged by standards, so it is impossible to produce products with stable quality, and the shelf life is not long, and it is easy to deteriorate and cause poor feeding effect, and even lead to frequent deaths of livestock and poultry. It is difficult to exert the application of biological fermentation technology in livestock and poultry production. some advantages
Its disadvantages are: while producing digestive enzymes, Aspergillus niger will also produce certain mycotoxins. When this product exceeds 2% in the feed, it will be harmful to livestock and poultry; if the amount exceeds 10%, it will even cause livestock and poultry death, so it cannot be safely used in livestock and poultry feed

Abstract

The invention discloses a preparation method of microbial fermentation feed, comprising the following steps: (1) preparing a fermentation; (2)preparing a strain; (3) rejuvenating a lactobacillus strain; (4) preparing strain mixed liquor; (5) adding the fermentation into a batch mixer after the prepared fermentation is smashed by a smasher, metering the prepared strain mixed liquor by a flowmeter, adding into the batch mixer to be mixed and stirred, sending the evenly mixed material into a solid fermenting vat via an auger to be fermented to obtain a fermentation mixture; and (6) adding the fermentation mixture into a drier to be dried to obtain material mixture, lowering temperature of material mixture, and smashing, and packaging and putting into a bag to obtain the microbial fermentation feed. The feed prepared with the invention has stable quality, has the small possibility of going bed and is harmless to livestock and poultry.

Description

technical field [0001] The invention relates to the field of livestock and poultry feeding, in particular to a method for preparing microbial fermented feed. Background technique [0002] In the field of livestock and poultry feeding, fermentation technology has been applied to feed. At present, there are generally the following fermentation methods: [0003] a. The saccharified feed technology belongs to the natural fermentation of the inherent microorganisms in nature under the natural state. Its disadvantages are: due to differences in regions and climates, the variety and quantity of beneficial microorganisms in nature and the existence of other harmful microorganisms, coupled with the variety, quality and proportion of feed raw materials, the saccharification effect of feed varies widely, and even corruption occurs , leading to a decline in the production efficiency of livestock and poultry or even death, which ultimately makes the technology unable to be promoted. ...
