Embodiment 1

[0014] Example 1: Production of solid-state fermented micro-ecological feed with rice bran as the main raw material

[0015] Calculated by weight, take 100Kg of fresh rice bran to remove impurities, add water until the moisture content of the rice bran is 16%-18%, use twin-screw extrusion technology, set the extrusion temperature to 135°C, the pressure to 0.6kpa, and the fresh rice bran for 15s. Stabilization treatment is carried out to passivate the activity of lipolytic enzymes and lipoxygenases that easily cause rice bran to deteriorate. Put the stabilized rice bran into a microwave sterilizer, set the sterilization temperature to 80°C, and the sterilization time to 5 minutes for microwave sterilization, which further stabilizes the rice bran while sterilizing the rice bran.

Embodiment 2

[0017] Calculated by weight, take 0.5g of enzyme bacteria, 0.3g of Bacillus subtilis, 0.25g of saccharomyces, and 0.4g of Lactobacillus, mix them and inoculate them on the slope of PDA medium, and cultivate them at a constant temperature of 30°C for 3-5 days. Generate seed media. Then inoculate it in a petri dish, and culture it in the dark at 30°C with a relative humidity of 65%-75%. After 8 days, cut it into small pieces under aseptic conditions and inoculate it in a sterilized culture bottle containing 2Kg rice bran. (the inoculum size is 5 bottles / petri dish), continue to cultivate under the same conditions for 10d, then insert rice bran as the working strain, and the inoculum size is 15% (being the working strain: sterilized Zhouqin 15: 85 (W: W)). Add water to the rice bran at a ratio of 1:1 (W:W) in advance, and stir evenly, then put it into high-temperature-resistant plastic, and sterilize it at 121°C for 2 hours. After inoculation, the rice bran was placed in a cons...

Embodiment 3

[0019] Calculated by weight, weigh 1Kg and 5Kg of the rice bran fermented powder prepared in Example 2 and mix them evenly with ordinary protein feed (corn and soybean meal, etc.), and pack and obtain the finished product of rice bran micro-ecological feed.

Abstract

The invention discloses a solid-state fermentation method for producing a microecological feed with rice bran as a main raw material, which belongs to the technical field of fine processing of agricultural and sideline products. The method comprises the following steps: (1) combiningly inoculating probiotics of ferment bacteria, bacillus subtilis, microzyme, lactobacillus acidophilus and the like together on a yeast powder-peptone-agar slant and allowing a seed culture medium to be generated at a certain temperature in a certain period of time; (2) carrying out stabilization treatment on fresh rice bran by using the technology of twin-screw extrusion and carrying out sterilization on the rice bran by using the technology of microwave drying and sterilization; (3) inoculating seed hypha into the sterilized rice bran and carrying out solid-state fermentation at a constant temperature; (4) drying and crushing the rice bran after fermentation is finished to obtain fermented rice bran powder; (5) mixing the fermented rice bran powder with a protein feed (corn, soybean meal and the like) in proportion to prepare the microecological feed. Mycoprotein produced in the fermentation process of the rice bran can be directly absorbed by animals. The prepared microecological feed can improve digestive intestinal tract of animals and enhance body immunity of the animals. The invention provides the industries of livestock breeding with a novel, highly efficient, harmless and pollution-free option.

Description

technical field [0001] The invention relates to a method for producing micro-ecological feed, in particular to a method for producing micro-ecological feed by solid-state fermentation of rice bran as a main raw material. Background technique [0002] In recent years, food safety incidents have emerged one after another, and each incident has left people with painful memories. Feed safety as the "source" of food safety has attracted more and more attention. [0003] With the rapid development of animal husbandry, the probability of disease prevalence is also increasing rapidly. Farmers abuse feed additives, antibiotics and even prohibited drugs to ensure their own interests, resulting in excessive drug residues in animal products, which enter the human body through food, causing human drug poisoning and allergic reactions. After long-term use of certain antibiotics by livestock and poultry, the bacteria will adapt to this type of antibacterial drug or the genetic material ...
