Method for preparing soybean straw feed

Abstract

The invention discloses a method for preparing soybean straw feed. After being diluted by water, cellulase and lactobacillus series are mixed proportionally, then sprayed to the surface of straw and turned and mixed to be uniform; after the sectioned straw is compacted, a plastic film coats the sectioned straw so that the straw and air can be isolated, and after sealed storage for 90 d, the soybean straw feed can be obtained. According to the method, the content of soluble protein, reducing sugar and lactic acid in soybean straw can be remarkably increased, and the palatability of the feed isimproved; on the basis, a small amount of dihydrocapsaicin and tricin is added, the sheep immunity can be effectively improved, and the weight gaining effect is obvious.

Description

Technical field [0001] The invention relates to the technical field of feed, in particular to a method for preparing soybean straw feed. Background technique [0002] With the increase in the amount of food crops planted and the increase in output, plant straws are also produced in large quantities as by-products of food crops. The most original use of these straws is to use as fuel, to make fires for cooking and heating. But with the improvement of people's living standards and the use of electricity, coal, and natural gas, this primitive use will gradually be eliminated by people. The treatment of plant straw has also become a serious pollution problem. The existing treatment methods such as crushing and burying the straw to carry out the so-called straw return to the field are not mature enough and practically applied. What's more, burning the straw after harvesting will not only seriously affect the environment and cause air pollution, but also have a greater negative impact...

AI Technical Summary

Problems solved by technology

The treatment of plant straw has become a serious pollution problem. In the existing treatment methods, such as crushing and burying the straw for so-called straw returning to the field, the technology of this method is not mature enough, and its practical application is seldom.

What's more, burning the straw after harvesting crops will not only seriously affect the environment and cause air pollution, but also have a relatively large negative impact on roads, civil aviation and other traffic. This practice is also prohibited by national laws.

[0003] There is also a considerable history of plant stalks used as feed to feed livestock such as cattle and sheep, but this feeding method is only extensive feeding, and the straw used is limited to corn stalks. Generally, corn stalks are directly crushed for feeding, but this kind of feeding Method The utilization rate of straw is too low, and the feeding effect is not good. If the cut corn straw is used to feed cattle, the remaining straw that cannot be eaten is more than one-third, resulting in serious waste of straw

Moreover, the feeding method of animals directly eating straw has extremely low bioavailability

The green storage straw feed developed later is to crush the straw and directly bundle and stack it for natural fermentation. The defect of this straw feed is that there are too many natural microorganisms in nature, which often spoil and deteriorate during the storage and fermentation process. Use and short storage time

At present, Lactobacillus brucelli is the most widely used commercial bacterial agent, but its inhibitory effect is not obvious under certain conditions, such as low temperature and short-term storage
