Preparation method of bran protein solidified fermented feed

Abstract

The invention discloses a preparation method of a bran protein solidified fermented feed. The preparation method comprises the following steps of (1) selecting strains in a compounding ratio: selecting geotrichum candidum which is 3% of the total weight of materials, candida utilis which is 4% of the total weight of the materials, and saccharomyces cerevisiae which is 4% of the total weight of thematerials, and performing mixed fermentation; and (2) preparing bran: crushing bran, performing screening with a 60-mesh sieve, adding nutritive salt liquor which is 0.8% of total weight of dried materials, wherein the nutritive salt liquor comprises 0.05% of potassium dihydrogen phosphate, 0.024% of sodium dihydrogen phosphate, 0.04% of sodium dihydrogen phosphate, 0.06% of potassium nitrate and0.013% of ammonium chloride. According to the preparation method disclosed by the invention, the bran is subjected to single cell protein transformation, so that bran protein transforming substanceswhich are high in protein content, rich in nutrition and good in palatability are produced; and besides, a solidified fermentation manner is adopted, so that the bran can be effectively utilized and transformed in a short time, and the economical efficiency of the bran can be better.

Description

technical field [0001] The invention relates to a feed preparation method, in particular to a preparation method of bran protein solidified fermented feed. Background technique [0002] The shortage of high-quality feed resources in my country has always restricted the long-term development of animal husbandry. Bran is the outermost skin of wheat, which is rich in nutrients and contains 15% protein and other nutrients. The traditional method is to use it directly But because of its poor palatability, the feed intake rate of cattle and sheep is low, and the feeding effect is not good. Using the method of microbial fermentation, Dingfen and fiber substances in bran can be directly converted into cattle and sheep. Ingested single-cell protein feed. However, different strains and feeding ratios will affect the effect of bran protein conversion, and different processes will also affect the efficiency of bran protein conversion. In the prior art, there is a lack of a preparation me...

[0002] The shortage of high-quality feed resources in my country has always restricted the long-term development of animal husbandry. Bran is the outermost skin of wheat, which is rich in nutrients and contains 15% protein and other nutrients. The traditional method is to use it directly But because of its poor palatability, the feed intake rate of cattle and sheep is low, and the feeding effect is not good. Using the method of microbial fermentation, Dingfen and fiber substances in bran can be directly converted into cattle and sheep. single cell protein feed

However, different strains and feeding ratios will affect the effect of bran protein conversion, and different processes will also affect the efficiency of bran protein conversion. In the prior art, there is a lack of a preparation method for bran solidified fermented protein feed. Make it possible to maximize the conversion of bran protein, and quickly enter the feed fermentation in a short period of time
