The silage is a coarse fodder obtained by cutting green fodder with a certain water content, forming an acidic environment through the fermentation effect of anaerobic lactobacillus carried in straw and other raw materials under the closed anoxic condition, and inhibiting the propagation of various mixed bacteria. The silage is sour and fragrant in smell, soft and juicy, good in palatability, rich in nutrition and beneficial to long-term storage, is an excellent feed source for herbivorous animals such as cattle and sheep, and is one of the main methods for solving the problem of lack of fresh pasture in winter in livestock production.
The northwest region of China has a natural high-quality pasture, but the supply of fresh pasture cannot be guaranteed in autumn and winter, so that regional dominant crops need to be searched, and silage is prepared according to a reasonable proportion to be used as feed to solve the problem of fresh pasture shortage. Chenopodium quinoa (Chenopodiaceae, Chenopodium), beet (Chenopodiaceae), oat (Gramineae), naked oat (Gramineae) and potatoes are all regional dominant crop varieties which can be planted in the cold and arid regions in northwest, and after the harvesting is finished, the waste straws and stems and leaves still have high application value, but the problem of incomplete nutrition still exists when the waste straws and leaves are used as silage raw materials; alfalfa enjoys the reputation of the king of pasture, belongs to perennial leguminous pasture, has the characteristics of high yield, rich nutrition, good palatability, easiness in digestion of livestock and the like, but loses more nutrients in the airing process.
In the prior art, crop straws or pasture are directly mixed and fermented to produce silage, so that nutrient substances in raw materials cannot be well reserved, the silage is low in crude protein content, high in crude fiber content and long in fermentation period.
Therefore, waste straw resources are fully utilized, raw materials with reasonable proportion are selected, components of silage additives are adjusted, and the silage with complete nutrition and suitable crude protein and crude fiber content is developed, so that the problem of insufficient feed in autumn and winter in arid and barren areas in the northwest of China can be effectively solved.

Examples 2-11 preparation of cattle silage
Examples 2-11 are a method of preparing cattle silage, respectively, and the process steps are similar to example 1, except that: the relevant parameters and results are different, and are shown in tables 1-2.
Table 1 examples 2-7 raw materials and parameter tables
Table 2 examples 8-11 raw materials and parameter tables
The prepared cattle silage N2-N11 has acid fragrance, no odor, dark green color, soft texture and no stickiness, and shows that the raw materials in the proportion are suitable for being mixed to prepare the silage.
Example 12 cattle silage nutritional parameters testing
(I) detection of nutritional parameters of the cattle silage
Detecting the nutritional parameters of the cattle silage N1-N11 prepared in the embodiment, wherein the determination of pH, lactic acid and butyric acid is carried out according to DB 15/T1458-2018; the determination of the dry matter is calculated according to the determination of GB/T6435-2014; the crude protein is determined according to GB/T6432-2018; the measurement of the crude fat is based on GB/T6433-2006; the measurement of the crude fiber is based on GB/T6434-2006;
the results are reported in tables 3-4:
TABLE 3 cattle silage nutrition parameter test results
TABLE 4 cattle silage nutrition parameter test results
The content of crude protein, crude fat and crude fiber is an important index for feed evaluation, and the higher the content of crude protein in the feed is, the higher the feeding value of the feed is; the crude fat is an index second to the crude protein, and has higher feeding value when the crude fat is more; the content of coarse fiber in the feed is used as a third index, and the feed quality is not improved due to the excessive content of the coarse fiber.
The pH value of the environment is sharply reduced by acids such as lactic acid and butyric acid, the growth and the propagation of acid-resistant putrefying bacteria are effectively inhibited, and the functions of corrosion prevention and freshness preservation are achieved, so the method is also a reference index for evaluating the quality of the feed.
From tables 3-4, it can be seen that from the contents of crude protein and crude fat, the contents of the two indexes of each group of the cattle silage N1-N4 are higher, and the cattle silage N2 has better quality, the contents of the crude protein and the crude fat in the cattle silage are high, and the content of the crude fiber is low, so that the cattle silage has good palatability and is easy to digest and absorb by cows;
comparing the groups, the results show that the contents of crude protein and crude fat in the groups of the cattle silage N8-N11 are the least, and the overall nutritional value is different from that of the cattle silage N5-N7; the cattle silage N5-N7 has less crude protein and crude fat content in each group, and the whole nutritive value is not as good as that of the cattle silage N1-N4.
The results of each group show that the content of crude protein in the feed is reduced along with the reduction of the ratio of the alfalfa, and the content of crude fiber in the feed is increased due to the addition of excessive alfalfa, so that the quality of the feed is not improved; as the content of potato straws and beet stems and leaves increases, the content of crude fat and crude protein also shows a descending trend, so the proportion of the alfalfa in the green feed needs to be strictly controlled in the feed preparation process.
(II) detecting silage and nutrition parameters of control group cattle

Control cattle silage D1-D3 was prepared according to the method of example 2, except that the contents of alfalfa, potato straw and sugar beet stems and leaves in the silage were different, the amount of additives and other preparation methods were the same as in example 2, and the specific raw materials are shown in Table 5.
TABLE 5 raw material Table of cattle silage D1-D3 of control group
The contents of crude protein, crude fat and crude fiber in the control cattle silage D1-D3 are detected, and the results are shown in Table 6:
TABLE 6 test results of nutritional parameters of cattle silage of control group
The results in tables 3 and 6 show that the ratio of alfalfa in the silage has a significant effect on the content of crude protein and crude fiber in the silage, and meanwhile, the content change of alfalfa, potato straw and beet stem leaves affects the whole nutrient content of the silage, and the alfalfa, the potato straw and the beet stem leaves are indispensable to the three, and the cattle silage N2 prepared in example 2 has the highest quality.
