Problems solved by technology

[0007] The main technical problem to be solved by the present invention is to provide a kind of rumen digester for most poultry and livestock which do not contain enzymes capable of digesting cellulose, insufficient utilization of cellulose food nutrition, and low protein content in animal feed. A method for preparing animal feed by microbial fermentation. In this method, ginkgo biloba is used as a fermentation substrate, and nitrogen, phosphorus, and glucose are added as nutrients to inoculate rumen contents. First, anaerobic fermentation is performed, and then yeast is inoculated to continue aerobic fermentation. The fermentation product The semi-finished feed is obtained by drying, and then the wheat distiller's grains in the rectification section are inoculated with yeast to continue fermentation. After drying, it is mixed with the semi-finished feed, crushed and sieved, and packaged to obtain an animal feed prepared by fermentation of rumen microorganisms.

example 1

[0020] Take 300g of ginkgo leaves, wash them with deionized water for 3 times, clean the floating dust on the surface, then expose them to the hot sun for 4 hours, put the dried ginkgo leaves into a jet mill for crushing, put them into a 1L beaker, add 10g of phosphoric acid diphosphate Potassium hydrogen, 8g ammonium sulfate, 15g magnesium sulfate and 12g carbonamide, add distilled water and be placed on the magnetic stirrer as 1:3 by solid-liquid ratio, stir 30min with the rotating speed of 300r / min, make ginkgo leaf fermentation culture mixture; Take out the rumen content from the rumen in the fresh cow stomach just slaughtered, weigh 100g of the rumen content and put it into a fermenter, add the above-mentioned Ginkgo biloba fermentation culture mixture, and then feed nitrogen into the fermenter to exhaust the air. Seal the mouth of the tank with a film, put it in an incubator for anaerobic fermentation at 35°C for 2 days; open the film after anaerobic fermentation, inocula...

Abstract

The invention relates to a method for preparing an animal feed by the fermentation of rumen microorganisms and belongs to the field of feed preparation. The method comprises the following steps: by taking gingko leaves as a fermentation primer, adding nitrogen and phosphorus, glucose and the like as nutrient substances; inoculating rumen content; carrying out anaerobic fermentation and then inoculating saccharomycetes to continually carry out aerobic fermentation; drying a fermentation product to prepare a feed semi-finished product; then taking a wheat vinasse liquid in a rectification section and inoculating the saccharomycetes to continually ferment; and drying and mixing the product with the feed semi-finished product, crushing and sieving, and packaging to obtain the animal feed prepared by the fermentation of the rumen microorganisms. The feed prepared by the invention contains a lot of cellulose type nutrient substances and contains a lot of protein, so that the growth and development of animals are facilitated.

Description

technical field [0001] The invention relates to a method for preparing animal feed by fermentation of rumen microorganisms, belonging to the field of feed preparation. Background technique [0002] The rumen is unique to ruminants. It is the largest of the four stomachs of adult ruminants, accounting for 80% of the total volume of the four stomachs. There are a large number of microorganisms growing and multiplying in it, and a large part of the feed is digested here. Rumen microorganisms can digest crude fiber, decompose sugar, starch and protein; synthesize amino acid and protein. [0003] The rumen content is the nutrient-rich chyme produced by the fermentation of the forage fed by ruminant livestock under the action of rumen microbial flora. It contains undigested grass feed, microbial flora, metabolites and gastric juice. The rumen contents after slaughtering cattle and sheep can be used as feed resources for livestock and poultry after proper treatment. [0004] Rume...
