Embodiment 1

[0043] A preparation method of fermented algae powder, the steps are as follows:

[0044] (1) Dry and pulverize macroalgae, pass through a 40-mesh sieve, sterilize by high-pressure steam at 121°C for 15 minutes, cool to room temperature, and set aside;

[0045] (2) Centrifuge the culture fluid of Chlorella and Chrysophylla respectively to obtain the algae mud of Chlorella and Chrysophylla; mix the algae mud of Chlorella and Chrysophylla according to the weight ratio of 1:1, and add 10% sterilized macroalgae powder, mixed evenly to obtain algae mixture;

[0046] (3) Add 1.8% compound microbial bacterial agent to the algae mixture, ferment for 24-36 hours at 32°C;

[0047] (4) After the fermentation is completed, add mannitol with a total weight of 5% to the fermented product, mix evenly, and vacuum freeze-dry to form a powder to obtain fermented algae powder.

[0048] The composite microbial bacterial agent is composed of Bacillus subtilis and Lactobacillus rhamnosus in a mas...

Embodiment 2

[0056] A preparation method of fermented peanut meal is:

[0057] (1) Mechanically pulverize the peanut meal, pass through a 20-mesh sieve, and sterilize by high-pressure steam at 121°C for 30 minutes. After the sterilization is completed, cool to room temperature;

[0058] (2) Adjust the moisture content of the sterilized peanut meal to 55-65%, inoculate the fermentation strains of 8% Aspergillus oryzae and 4% Aspergillus niger into the peanut meal, and after fully mixing, carry out solid-state fermentation at 28°C-32°C , after 36 hours of fermentation, and then 48 hours of fermentation at 32-35°C;

[0059] (3) Add 1 times the weight of deionized water to the material after the above-mentioned fermentation is completed, adjust pH 7.0, 40°C, enzymolysis 2h; adjust pH 4.5, 40°C, enzymolysis 4h; after enzymolysis, 100 ℃, treated for 10 minutes, cooled to room temperature, that is.

[0060] Activation of Aspergillus oryzae and Aspergillus niger and preparation of fermentation s...

Embodiment 3

[0065] A compound fermented feed for dairy cows, consisting of the following components in parts by weight:

[0066] 20 parts of rice husk, 46 parts of fermented peanut meal, 50 parts of ammoniated corn stalks, 10 parts of fermented algae powder, 2 parts of chitosan oligosaccharide, 2 parts of oyster powder, and 2 parts of medical stone powder.

[0067] The preparation method of compound fermented feed for described cows, the steps are as follows:

[0068] (1) Weigh rice husks, fermented peanut meal, ammoniated corn stalks, and fermented algae powder according to the amount and mix them evenly. Adjust the water content to 65-70%. 32°C, stack for 5-6 hours;

[0069] (2) Add chitosan oligosaccharide, oyster powder, and medical stone powder to the mixture in 1), add it into a mixer, stir evenly, and discharge.

[0070] The preparation method of the ammoniated corn stalks is:

[0071] (1) remove sundries from corn stalks, cut them into small sections of 1-2 cm, soak them with w...

Abstract

The invention discloses a composite fermented feed for cows, and a preparation method and application of the composite fermented feed, and belongs to the technical field of biological fermented feeds.The composite fermented feed for cows disclosed by the invention consists of the following components in parts by weight: 20-30 parts of rice husks, 46-68 parts of fermented peanut meal, 50-70 partsof ammoniation corn straw, 10-18 parts of fermented algae powder, 2-5 parts of chitosan oligosaccharide, 2-4 parts of oyster powder and 2-4 parts of maifan stone powder. According to the composite fermented feed for cows disclosed by the invention, the components are reasonable in collocation, so that the milk production of the cows can be increased, and the nutritional quality of produced milk can also be increased; and according to the composite fermented feed disclosed by the invention, the intestinal microecology environment of the cows is improved, so that the digestion situation of nutrient components can be improved, the capacity of organisms for absorbing calcium and phosphorus can be increased, and nitrogen metabolism can be strengthened.

Description

technical field [0001] The invention belongs to the technical field of biological fermented feed, and in particular relates to a compound fermented feed for dairy cows, its preparation method and application. Background technique [0002] At present, with the development of animal husbandry, large-scale dairy cow breeding is becoming more and more large-scale, scientific and economical. As the output of the aquaculture industry increases year by year, consumers have higher and higher requirements for quality. For large-scale aquaculture, the quality of feed directly determines the quality of aquaculture products. At present, there are many kinds of cattle feeds in the market, with different functions. Among them, dairy cows have different nutritional requirements in different growth and physiological periods, and the feeds they feed can also be different, and special preparation is required. [0003] The existing dairy cow feed formula has a single protein feed, improper am...
