Problems solved by technology

[0003] Lysine and protein are essential nutrients for animals. The common practice of enterprises is to add lysine fermented products and protein components to the feed to increase the content of lysine and protein in the feed. At present, the conventional method of preparing feed has the following disadvantages : First, the processing technology is complex, and the amino acid and protein content of the feed can not meet the needs of animals; second, after lysine has been producing acid by liquid fermentation, it is deacidified, purified, crystallized, and dried into lysine Pure amino acid powder has the disadvantages of high fermentation cost, very large post-processing cost, and increased feed cost; secondly, the disadvantages of the old method of liquid fermentation of Candida utilis are high requirements, large oxygen demand, easy acid production, and high cost , the post-processing process is troublesome, the investment in fixed assets is huge, and the rate of return is low. The lysine and protein content in the feed produced by conventional methods cannot meet the requirements, and the feed contains more acid, resulting in poor animal absorption. , low breeding efficiency

preparation example Construction

[0019] The present invention relates to a method for preparing a fermented high-lysine high-protein feed, the preparation steps of which are as follows:

[0020] Step 1: After expanding the lysine-producing bacteria, when the number of viable bacteria is ≥ 5 billion / g, add bran of the same weight as the bacterial liquid, and ferment in the bran carrier. The fermentation time is 72-80 hours at 80°C Dried, crushed to a particle size of <2.5mm to obtain a lysine fermented product, and set aside;

[0021] Step 2: Cultivate Candida utilis for 36-48 hours using malt juice agar medium at a temperature of 30-35°C, a relative humidity of 40-50%, and a pH value of the medium of 5.0-6.0, and take it out Final drying, the drying temperature is 40-60°C, and final crushing until the particle size is less than 2.5mm to obtain the yeast fermentation product, which is used for later use;

[0022] Step 3: crush the soybean meal to a particle size of ≤1 mm, and set aside;

[0023] Step 4: Grin...

Embodiment 1

[0029] Step 1: After screening the lysine-producing corynebacterium, the screening includes activation and rejuvenation, and the dominant strains are selected for use. After that, the strains are expanded and cultivated through primary and secondary strains. When the number of viable bacteria reaches 5 billion / g, Add bran with the same weight as the bacterial liquid, ferment in the bran carrier, and stop the fermentation after 72 hours of fermentation. At this time, the acid production reaches 10%, and the number of viable bacteria reaches ≥10 billion / g. After the fermentation is completed, the lysine The content is 5.5%, dried at 80°C, and crushed to a particle size of <2.5mm to obtain a lysine fermented product, which is set aside;

[0030] Step 2: Cultivate Candida utilis, stop the cultivation after 36 hours, the number of viable yeast cells reaches 200 million / g, and the drying temperature is 40°C; crush the particle size to <2.5mm, and obtain a yeast fermented product for ...

Embodiment 2

[0039] Step 1: After screening the lysine-producing corynebacterium, the screening includes activation and rejuvenation, and the dominant strains are selected for use. After that, the strains are expanded and cultivated through primary and secondary strains. When the number of viable bacteria reaches 5.5 billion / g, Add bran with the same weight as the bacterial liquid, ferment in the bran carrier, and stop the fermentation after 75 hours of fermentation. At this time, the acid production reaches 12%, and the number of viable bacteria reaches ≥10 billion / g. After the fermentation is completed, the lysine The content is 6%, dried at 80°C, crushed to a particle size of <2.3mm, and the lysine fermented product is obtained, which is set aside;

[0040] Step 2: Cultivate Candida utilis, stop the cultivation after 42 hours, the number of viable yeast cells reaches 200 million / g, and the drying temperature is 50°C; the crushed particle size is less than 2.5mm, and the yeast fermented p...

Abstract

The invention discloses a method for preparing a fermented high-lysine high-protein feed. The method comprises the following steps of: preparing a lysine fermented material and a yeast fermented material; and crushing the lysine fermented material, the yeast fermented material, bean pulp and corn protein powder, and mixing to obtain a finished product. The processing cost is low, and the method is convenient to operate; the content of lysine and protein in the feed is increased, the experiment proves that the feed prepared by the method has the crude protein content of more than or equal to 40 percent and the lysine content of more than or equal to 8 percent, and the demand of animals on the lysine and the protein is met; moreover, the absorption effect of the animals is high, and the breeding benefit is improved.
