Problems solved by technology

However, corn stalks with a growth period of less than 115 days will lose 30-50% of their nutrients during processing after harvesting, mainly including the loss of water, sugar and protein, resulting in low nutritional content of the feed, poor palatability, and difficult to feed. Digested by farmed animals such as cattle and sheep

Embodiment 1

[0034] A kind of preparation method of utilizing compound microbial inoculum to obtain yellow storage feed, all know in the art that the corn stover of yellow storage is dry corn stover with a water content of 10-20%, and it is characterized in that:

[0035] First, the corn stover was pretreated with a mixed solution of hydrogen peroxide solution, urea and distilled water, specifically:

[0036]After short pulverizing the corn stalk, add it into a mixed solution consisting of hydrogen peroxide, urea, and distilled water, wherein the weight percentages of the corn stalk, hydrogen peroxide, and urea are 35%, 3%, and 1%, respectively, and the rest are distilled water. ; Then, the temperature was kept at 40° C. for 3 hours; finally, the corn stalks pretreated by the mixed solution were filtered and dried by a filter device and used for later use.

[0037] Then the cultured compound microbial inoculum is added to the pretreated corn stalk, that is, 10 mL of compound microbial inoc...

Embodiment 2

[0055] A preparation method for obtaining yellow stock feed by utilizing a composite microbial inoculum, characterized in that:

[0056] First, the corn stover was pretreated with a mixed solution of hydrogen peroxide solution, urea and distilled water, specifically:

[0057] After short pulverizing the corn stalk, add it into a mixed solution consisting of hydrogen peroxide, urea, and distilled water, wherein the weight percentages of the corn stalk, hydrogen peroxide, and urea are 40%, 6%, and 2%, respectively, and the rest are distilled water. ; Then, the temperature was kept at 43° C. for 4 hours; finally, the corn stalks pretreated by the mixed solution were filtered and dried by a filter device and used for later use.

[0058] Then the cultured compound microbial inoculum is added to the pretreated corn stalk, that is, 10 mL of compound microbial inoculum is added to the pre-treated corn stalk per 1 kg of mixed solution, and then 100 mL of distilled water is used for uni...

Embodiment 3

[0076] A preparation method for obtaining yellow stock feed by utilizing a composite microbial inoculum, characterized in that:

[0077] First, the corn stover was pretreated with a mixed solution of hydrogen peroxide solution, urea and distilled water, specifically:

[0078] After short pulverizing the corn stalk, add it into a mixed solution consisting of hydrogen peroxide, urea, and distilled water, wherein the weight percentages of the corn stalk, hydrogen peroxide, and urea are 45%, 8%, and 3%, respectively, and the rest are distilled water. ; Then, the temperature was kept at 45° C. for 5 hours; finally, the corn stalks pretreated by the mixed solution were filtered and dried by a filter device and used for later use.

[0079] Then the cultured compound microbial inoculum is added to the pretreated corn stalk, that is, 10 mL of compound microbial inoculum is added to the pre-treated corn stalk per 1 kg of mixed solution, and then 100 mL of distilled water is used for uni...

Abstract

The invention provides a method for preparing yellow corn silage feed by utilizing a compound microbial agent. The method comprises the following steps: firstly, pretreating corn straws by adopting a mixed solution; then adding the cultured compound microbial agent to the pretreated corn straw; and finally, bagging the corn straws added with the compound microbial agent, vacuumizing and culturing to obtain the yellow corn silage feed. Wherein the mixed solution is formed by mixing a hydrogen peroxide solution, urea and distilled water; the compound microbial agent comprises lactobacillus plantarum, lactobacillus rhamnosus and saccharomyces cerevisiae. According to the method, the compound microbial agent is used for treating the yellow corn silage feed, no antibiotic needs to be added, the quality of the yellow corn silage feed can be effectively improved, and the yellow corn silage feed is easy to digest, high in nutritional value, good in palatability and capable of effectively reducing digestive system diseases.

Description

technical field [0001] The present invention relates to the technical field of feed additives, in particular to a method for preparing yellow storage fodder by using a composite microbial inoculum. Background technique [0002] Fermented feed plays a very important role in the production of animal husbandry, especially nowadays, with the rapid development of animal husbandry, the demand for high-quality forage is also increasing, and the worldwide problem of food shortage is becoming more and more serious. It has gradually become the focus of attention of groups from all walks of life. Therefore, the development of microbial feed production is particularly important. [0003] Microbial fermented straw is an effective storage method for straw-based feed. On the basis of ensuring (or enhancing) the nutrition of straw, it can improve the palatability and make it easier for animals to digest and absorb; The fresh (i.e. green) straw or the transformed straw (i.e. yellow) stra...
