Problems solved by technology

[0003] Northwestern China has natural high-quality pastures, but the supply of fresh pastures cannot be guaranteed in autumn and winter. Therefore, it is necessary to find geographically superior crops and make silage with a reasonable ratio to solve the problem of shortage of fresh pastures as feed.
Quinoa (Chenopodiaceae), sugar beet (Chenopodiaceae), oats (Graceae), naked oats (Graceae) and potatoes are all geographically dominant crop varieties that can be planted in the alpine and barren areas of Northwest China. After harvesting, they are discarded The stalks and stems and leaves of Alfalfa still have high application value, but there are still problems of incomplete nutrition when used as silage raw materials; Good palatability and easy digestion by livestock, etc., but alfalfa loses more nutrients in the drying process
[0004] In the prior art, silage is produced by directly mixing and fermenting crop stalks or pastures, which cannot well retain the nutrients in the raw materials. The silage has low crude protein content, high crude fiber content and long fermentation period

Embodiment 1

[0023] Embodiment 1 A kind of preparation method of cattle silage

[0024] The green material is green alfalfa, quinoa, oats, naked oats, green stalks of potatoes after picking, and green beet stems and leaves.

[0025] Take 28kg of alfalfa, 24kg of quinoa straw, 23kg of oat straw, 15kg of naked oat straw, 5kg of potato straw and 5kg of beet stems and leaves, cut them to a length of 2cm, add 0.2kg of sodium benzoate and 0.4kg of propionic acid, mix well, and load In a 100L silage pit, tamp, seal, and ferment for 40 days at 25°C to obtain cattle silage, which is marked as N1.

[0026] The raw materials used can be purchased from the market. After testing, the water content of green materials in the raw materials is 60-70%, among which, the water content of alfalfa is 63.2%, the water content of quinoa straw is 65.1%, and the water content of oat straw is 60%. , Naked oat stalks have a water content of 65.8%, potato stalks have a water content of 63.2%, and sugar beet stems and...

Embodiment 2-11

[0028] The preparation method of embodiment 2-11 cattle silage

[0029] Examples 2-11 are respectively a method for preparing cattle silage, the process steps of which are similar to those of Example 1, the only difference being that the relevant parameters and results are different, see Table 1-2 for details.

[0030] Table 1 Example 2-7 raw materials and parameter table

[0031]

[0032] Table 2 Embodiment 8-11 raw material and parameter list

[0033]

[0034] The prepared cattle silage N2-N11 has a sour smell, no odor, dark green color, soft silage texture, not sticky, showing that the above ratio of raw materials is suitable for mixing to make silage.

Embodiment 12

[0035] Example 12 Detection of Cattle Silage Nutritional Parameters

[0036] (1) The nutritional parameter detection of cattle silage of the present invention

[0037] The nutritional parameters of cattle silage N1-N11 obtained in the above examples are detected, wherein the determination of pH, lactic acid and butyric acid is based on DB15 / T 1458-2018; the determination of dry matter is calculated according to GB / T 6435-2014 Draw; The determination of crude protein is based on GB / T 6432-2018; The determination of crude fat is based on GB / T 6433-2006; The determination of crude fiber is based on GB / T 6434-2006;

[0038] The recording results are shown in Table 3-4:

[0039] Table 3 Test results of nutritional parameters of cattle silage

[0040]

[0041] Table 4 Test results of nutritional parameters of cattle silage

[0042]

[0043] Crude protein, crude fat and crude fiber content are important indicators for feed evaluation. The higher the crude protein content in ...

Abstract

The invention belongs to the technical field of feed, and discloses cow silage and a preparation method thereof. The cow silage is prepared in a way that green feed consisting of Medicago sativa L., Chenopodium quinoa Willd. straws, Avena sativa L. straws, Avena chinensis (Fisch. ex Roem. et Schult.) Metzg. straws, potato straws and Beta vulgaris L. stems and leaves, and an additive consisting of sodium benzoate and propionic acid are evenly mixed, sealed and fermented. The silage which has a simple preparation method, comprehensive nutrients and a proper crude protein and crude fiber content is developed by fully utilizing waste straw resources, selecting raw materials at a reasonable ratio and adjusting the components of the silage additive, and the problem that feed is insufficient in autumn and winter in arid and barren areas in northwest of China can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of feed production, and relates to a mammalian silage and a preparation method thereof, in particular to a cattle silage and a preparation method thereof. Background technique [0002] Silage is to chop the green feed with a certain moisture content, under the condition of airtight anoxic, through the fermentation of anaerobic lactic acid bacteria carried in straw and other raw materials, an acidic environment is formed, and the reproduction of various bacteria is inhibited. A roughage obtained. Silage has a sour and fragrant smell, is soft and juicy, has good palatability, is rich in nutrition, and is good for long-term preservation. [0003] Northwest China has natural high-quality pastures, but the supply of fresh pastures cannot be guaranteed in autumn and winter. Therefore, it is necessary to find geographically superior crops and make silage with a reasonable ratio to solve the problem of shortage of ...
