Problems solved by technology

However, the shortage of feed raw materials has always affected the development of animal husbandry and has become a major challenge facing my country's animal husbandry
If the grass is directly silaged after mowing, the high water content (80%-90%) will easily cause the fermentation of butyric acid, which will lead to failure, serious loss of nutrients, and serious reduction of palatability
In the prior art, preservatives are generally added to improve the quality of silage and prolong the storage time, but the addition will directly affect the safety of feed and affect the health of livestock.
[0003] Through the above analysis, the problems and defects in the prior art are: improving the quality of silage and prolonging the storage time by adding preservatives will directly affect the safety of the feed and affect the health of livestock

preparation example Construction

[0049] Such as figure 1 Shown, the preparation method for the compound additive that is used to prepare moisture silage that the embodiment of the present invention provides comprises the following steps:

[0050] S101, using rice washing water and fresh milk for fermentation to prepare a lactic acid bacteria fermentation liquid;

[0051] S102, crushing and beating the soaked corn to obtain corn steep liquor;

[0052] S103, taking part of the corn steep liquor, adding α-amylase for enzymolysis, then adding glucoamylase for enzymolysis, and concentrating under reduced pressure to obtain enzymolysis concentrated sugar solution;

[0053] S104, mixing the enzymatically hydrolyzed concentrated sugar liquid with the corn steep liquor prepared in S102, adding fermentation bacteria after stirring, and culturing to obtain an amino acid fermentation liquid;

[0054] S105, mixing copper sulfate, manganese sulfate, zinc sulfate, potassium iodide and calcium carbonate to obtain a trace e...

Embodiment 1

[0086] Use rice washing water and fresh milk for fermentation to prepare lactic acid bacteria fermentation broth;

[0087] Grinding and beating the soaked corn to obtain corn steep liquor; taking part of the corn steep liquor, adding α-amylase for enzymatic hydrolysis, and then adding glucoamylase for enzymatic hydrolysis, concentrating under reduced pressure to obtain enzymatic hydrolyzed concentrated sugar liquid; enzymatically hydrolyzed and concentrated The sugar solution is mixed with the corn steep liquor prepared in step 2, and after stirring, the fermentation bacteria are added for cultivation to obtain the amino acid fermentation liquid;

[0088] After mixing the lactic acid bacteria fermentation liquid and the amino acid fermentation liquid, add Bacillus subtilis, 30% acetic acid solution, Saccharomyces cerevisiae, and cellulase, and add copper sulfate, manganese sulfate, zinc sulfate, potassium iodide, and calcium carbonate during stirring to obtain Compound additiv...

Embodiment 2

[0090] Drying the rice straw to a water content of 60-65%, and pulverizing it in a pulverizer to obtain rice straw powder; drying the corn straw to a water content of 65-70%, and putting it in a pulverizer pulverized to obtain coarse grains of corn stalks;

[0091] The compound additive for preparing high-moisture silage prepared in Example 1 is mixed with water according to a volume ratio of 1:60, and after stirring, the high-moisture silage spraying agent is obtained;

[0092] Mix corn straw granules and rice straw powder, spray water silage spraying agent, control the water after mixing at 60%-70%, strictly seal and compact, ferment for 7-10 days; spray again, when silage fermentation material When there is a sour smell or wine smell, it means that it has matured and can be fed directly.

Abstract

The invention belongs to the technical field of feed preparation, and discloses a compound additive for preparing high-moisture silage as well as a preparation method and application of the compound additive. The preparation method of the compound additive for preparing the high-moisture silage comprises the following steps: crushing and pulping soaked corn, adding alpha amylase, adding glucoamylase, performing concentrating under reduced pressure to obtain enzymolysis concentrated sugar liquor; mixing the enzymolysis concentrated sugar solution with corn steep liquor, and adding zymophyte toobtain amino acid fermentation liquor; mixing copper sulfate with manganese sulfate, zinc sulfate, potassium iodide and calcium carbonate to obtain a trace element chelating agent; and mixing lactic acid bacteria fermentation liquor with the amino acid fermentation liquor, adding bacillus subtilis, a 30% acetic acid solution, saccharomyces cerevisiae and cellulase, and adding the trace element chelating agent while stirring. After being mixed and ensiled with a feed, the feed additive provided by the invention has the advantages of being good in palatability and capable of promoting feed intake and digestibility of cattle and sheep.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and in particular relates to a compound additive for preparing high-moisture silage and its preparation method and application. Background technique [0002] At present: my country's animal husbandry is developing rapidly, and the demand for feed as the basis for the development of animal husbandry is increasing year by year. However, the shortage of feed raw materials has always affected the development of animal husbandry and has become a major challenge for my country's animal husbandry. As an important area for the development of animal husbandry in my country, the south has the natural advantages of rich water and heat resources, long grass growth period, and high productivity per unit area of ​​grassland. However, there are still problems such as low grass utilization rate, backward production technology and business model that restrict the development of animal husbandry. Among t...
