Description

Technical Field

[0001] The invention relates to the technical field of feed, in particular to a mixed biological feed and a preparation method thereof. Background Art

[0002] Biomixed feed is a kind of animal feed or feed raw material produced by microbial fermentation technology. Its main feature is that it contains a large number of microorganisms such as lactic acid bacteria or yeast that are beneficial to animal health. This kind of feed uses microbial fermentation technology to deeply process the feed raw materials and provide rich nutrients such as amino acids, vitamins, enzyme preparations and organic acids.

[0003] Bio-mixed feed is usually composed of a variety of raw materials, including coarse grains, leaves, grass, distiller's grains, bean dregs, vegetables, fruits and insects. These raw materials are simply processed, such as cooking or fermentation, to fully utilize their nutritional value. The advantages of this feed are low cost and a wide range of feed sources, and the pork raised is delicious.

[0004] At present, people attach great importance to food safety and environmental protection. To solve the food safety problems caused by the abuse of antibiotics and the environmental pollution caused by the unreasonable discharge of livestock and poultry manure, vigorously developing biological feed is the main way to solve the problem. Biological feed is a safe, pollution-free, and drug-free high-quality feed containing active beneficial microorganisms. In view of this, people began to use microbial fermentation feed when feeding poultry, but the existing microbial fermentation feed has low fermentation efficiency, harsh fermentation conditions and complex operation, poor feed taste, low bioavailability and short shelf life, which makes it difficult for microbial fermentation feed to be widely promoted. Summary of the invention

[0005] The purpose of the present invention is to provide a mixed biological feed and a preparation method thereof, so as to effectively avoid the problems of poor nutrition, bad taste and short storage time of existing feed.

[0006] To achieve the above object, the present invention provides the following technical solutions: A mixed biological feed and a preparation method thereof, comprising the following steps: S1: Selection and preparation of raw materials: Select appropriate raw materials, including fruit residues, wheat bran, rice bran, straw, and chop and crush the raw materials; S2: Fermentation treatment: The prepared raw materials are mixed evenly and fermented. During the fermentation process, appropriate amounts of enzymes and probiotics, such as cellulase, pectinase, yeast, lactic acid bacteria, etc., need to be added to promote the decomposition of the raw materials and the release of nutrients; S3: Drying and crushing: After the fermentation is completed, the material is taken out and crushed and dried; S4: Add nutritional supplements: (1) Prepare the materials: including Junbaobei fermentation material microbial feed fermentation agent, water, brown sugar, corn flour or other grain flour. The specific ratio is: one bag of Junbaobei fermentation material microbial feed fermentation agent plus 100 kg of water, 2 kg of brown sugar, and 5-10 kg of corn flour; (2) Mixing materials: Place the above materials together in a ceramic or plastic bucket, stir briefly, and then seal and ferment for 3-7 days.

[0007] Preferably, the fermentation process in S2 usually needs to be carried out in a closed environment to ensure the fermentation effect.

[0008] Preferably, the water used in S4 needs to be warm water of 40 degrees Celsius in winter.

[0009] Preferably, the brown sugar raw material in S4 needs to be dissolved in water first.

[0010] Preferably, in addition to corn flour, other cereal flours may be used in S4.

[0011] Preferably, after the nutrient agent in S4 is fermented, it can be used according to different animal species: for pigs, 5%-10% of the weight of their feed can be mixed into the feed for piglets, 10%-15% for medium pigs, large pigs and sows; for dogs, cattle, sheep, rabbits, foxes, bamboo rats, guinea pigs and other animals, it can be used at a feed ratio of 5%-10%.

[0012] Preferably, the fermentation container in S4 cannot be filled to the brim, leaving one-third of the space for simple heat preservation. A large amount of gas will be generated during the fermentation process, and it needs to be deflated 1-2 times and stirred once a day until the fermentation is uniform.

[0013] Preferably, during the fermentation process in S4, the container needs to be compacted while being filled, and finally the opening is tied tightly or sealed with plastic cloth and placed in a cool place for anaerobic fermentation for 1 to 3 days / 3 to 7 days in winter.

[0014] In summary, due to the adoption of the above technology, the beneficial effects of the present invention are: 1. By adding microorganisms and enzymes, complex substances in feed, such as cellulose and hemicellulose, can be decomposed, thereby improving the digestibility and nutritional value of feed. These microorganisms can also synthesize nutrients such as B vitamins and amino acids to further supplement the nutrients needed by animals and promote animal growth.

[0015] 2. The probiotics in the biological mixed feed can compete with harmful bacteria in the intestine for living space and nutrients, inhibit the reproduction of harmful bacteria, and maintain the balance of intestinal flora. At the same time, these probiotics can also produce antibacterial substances such as organic acids and bacteriocins, enhance the intestinal barrier function, reduce the invasion of pathogens, and thus improve the immunity of animals.

[0016] 3. Improve the breeding environment and reduce pollution. Probiotics can decompose and utilize some indigestible substances in the animal body, reduce the content of harmful gases in feces, and reduce the odor of feces. At the same time, they can also promote the complete utilization of feed by animals and reduce the emission of organic matter in feces, which is of great significance to the protection of the ecological environment.

[0017] 4. Improve the digestion and absorption function and immune status of animals, and improve the quality of farmed products. For example, animals fed with biological feeds tend to have better carcass quality, more delicious and juicy meat, and more in line with food safety standards. At the same time, due to the reduction in the use of veterinary drugs, the problem of drug residues in farmed products has also been effectively solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention provides Figure 1 A mixed biological feed and preparation method shown includes the following steps: S1: Selecting the right raw materials is the first step in preparing biological feed. Common raw materials include fruit residues, wheat bran, rice bran, straw, etc. These raw materials need to be processed simply, such as chopping and crushing, to ensure that they are suitable for feed preparation requirements; S2: Fermentation: After the prepared raw materials are mixed evenly, fermentation is carried out. During the fermentation process, appropriate amounts of enzymes and probiotics, such as cellulase, pectinase, yeast, lactic acid bacteria, etc., need to be added to promote the decomposition of the raw materials and the release of nutrients. The fermentation process usually needs to be carried out in a closed environment to ensure the fermentation effect; S3: Drying and crushing: After fermentation is completed, the material is taken out and crushed and dried. The purpose of drying is to remove excess moisture and prevent the feed from getting moldy during storage. Crushing is to make the feed easier for animals to digest and absorb; S4: Adding nutritional supplements: In order to further improve the nutritional value and palatability of the feed, some nutritional supplements can be added to the feed. These supplements can not only improve the taste of the feed, but also promote the appetite of animals. The specific preparation method is as follows: (1) Prepare the materials: including Junbaobei fermentation material microbial feed fermentation agent, water, brown sugar, corn flour or other grain flour. The specific ratio is: one bag of Junbaobei fermentation material microbial feed fermentation agent plus 100 kg of water, 2 kg of brown sugar, and 5-10 kg of corn flour. In winter, the water needs to be 40 degrees Celsius warm water. The brown sugar raw material needs to be dissolved in water first. In addition to corn flour, other grain flours can be used; (2) Mixing materials: Place the above materials together in a ceramic or plastic barrel, stir briefly, and seal for fermentation for 3-7 days. The container should not be filled to the brim, and one-third of the space should be left, and simple insulation should be performed. A large amount of gas will be produced during the fermentation process, and the gas should be released 1-2 times and stirred once a day to ensure uniform fermentation; After fermentation, it can be used according to different animal species. For example, for pigs, 5%-10% of the weight of feed for piglets, 10%-15% for medium pigs, large pigs and sows (half the weight for pregnant sows, lactating sows and breeding stock) can be mixed into the feed for feeding. For dogs, cattle, sheep, rabbits, foxes, bamboo rats, guinea pigs and other animals, 5%-10% of the weight of feed can be used; Note: (1) During the preparation process, all materials must be clean and hygienic, free of impurities; (2) Pay attention to temperature control during the fermentation process to ensure that the fermentation agent can work normally; (3) When using, the proportion should be adjusted according to the actual situation of the animal to avoid excessive use that may cause adverse reactions; (4) After fermentation is completed, the nutrient solution should be sealed to avoid contact with air and deterioration. Example

[0023] Fruit residue biological feed: S1: Prepare fruit residue: First, you need to prepare fruit residue, which can include apple residue, pineapple residue and other fruits; S2: Mixing and softening: Mix the wheat bran, rice bran and water and put them into the storage chamber surrounded by the bellows with a sealed bottom, and seal the cover with a female cap to soften the wheat bran and rice bran in a closed environment; S3: First fermentation: Add cellulase and / or pectinase to the softened mixture, mix well and keep warm to carry out the first fermentation; S4: Second fermentation: air is introduced into the storage chamber, and at least two of yeast, lactic acid bacteria or Aspergillus niger are added, mixed evenly and kept warm for the second fermentation; S5: Drying and crushing: After being placed in a sealed storage chamber for a period of time, the food is taken out, crushed, and then dried to obtain biological feed; Among them: Since fresh pomace has high moisture and acidity, it is not easy to store, so silage can be used to solve the problem. When silaging, the pomace can be mixed with corn, hay, etc., and appropriate amounts of urea and microecological agents can be added to increase the protein content and silage quality; ‌Use of fermentation agent‌: During the fermentation process, composite microorganisms (probiotics) can be used as fermentation agents. For every 2 tons of pomace, 500 grams of 99 multifunctional feed fermentation agent and an appropriate amount of salt are used. After fermentation is completed, the feed needs to be strictly sealed and stored, and it can be kept without deterioration for one year. Example

[0024] Straw bio-feed: Straw bio-feed has high nutritional value and good palatability and is easy to digest and absorb.

[0025] S1: Select straw raw materials: Select appropriate straw raw materials according to the needs of different animals. For example, herbivorous animals (such as cattle, sheep, horses, etc.) can use corn straw, rice straw, wheat straw and other low-nutrient, high-fiber and lignin straw; while monogastric animals (such as pigs, ducks, geese, fish, etc.) need to choose materials with relatively high nutrition and low crude fiber and lignin, such as peanut vines, rice bran, etc. S2: Straw pretreatment: Remove the roots and soil from the selected straw, remove the moldy and deteriorated parts, and keep the straw fresh and fragrant. For ruminants, the straw can be chopped into pieces about 1 inch long; for monogastric animals, the straw needs to be crushed into fine bran; S3: Adding fermentation agent and nutrient agent: Use "enhanced straw-specific fermentation agent" and water to simply stir into a turbid liquid, and then mix it with dry straw, salt, corn flour, etc. For ruminants, the fermentation agent can be mixed with dry chopped straw, salt, corn flour, etc.; for monogastric animals, the fermentation agent needs to be mixed with dry straw powder, soybean meal, etc. S4: Fermentation: Compact the mixed straw material and cover it tightly, then place it at a suitable temperature for fermentation. For ruminants, the fermentation time is more than 12 hours; for monogastric animals, the fermentation time depends on the specific situation; S5: Storage: After fermentation is complete, store the feed in a sealed container and avoid direct sunlight. For long-term storage, the straw can be dried, sorted and stacked into piles, and the top can be covered with plastic sheeting or other rainproof facilities.

[0026] Through the above steps, straw can be effectively converted into biological feed, which not only reduces the cost but also improves the nutritional value and palatability of the feed.
