Straw treatment method and straw feed obtained by method

Abstract

The invention provides a straw treatment method and a straw feed obtained by the method, and belongs to the technical field of straw treatment. The straw treatment method comprises the steps that: rolling treatment is conducted on whole straw or aired cut straw to destroy the epidermal structure of the straw, and the process is conducted at a degree that sweet water does not flow out. The straw treatment method provided by the invention is especially suitable for corn straw. The method is simple in steps and convenient to operate, additives and silage pools are not needed, and the handling capacity is not limited. The obtained straw feed is easy to store, good in palatability and high in sweetness, and can be used for feeding livestock and poultry.

Description

technical field [0001] The invention belongs to the technical field of straw treatment, and in particular relates to a straw treatment method and straw feed obtained by the method. Background technique [0002] The output of crop straw, especially corn straw, in the south of the Yellow River and north of the Huaihe River is very large. Although there are various utilization methods, there is still a considerable gap between the goal of full quantitative utilization. [0003] The utilization of corn stover includes making hay and making silage. Among them, the production method of dry forage is relatively extensive, and it can be obtained by drying until it is dried. Due to extensive drying, the nutritional value of dry forage is reduced, the palatability of livestock is poor, and the feeding value is low. However, this method is easy to operate and does not require any investment. It can be done anywhere, so it is very common in rural areas and areas where there are scatter...

AI Technical Summary

Problems solved by technology

However, due to the high price of additives such as lactic acid bacteria and organic acids, the production cost of silage is increased, forcing many farmers to give up the use of silage.

[0006] In addition, the existing straw silage technology (such as the patent document with the application number CN201711109003.9) generally requires the use of special silage facilities such as silage ponds. How much can be processed at one time. When the processing volume is large, multiple silage ponds are needed. When the processing volume is small, the silage ponds cannot be effectively used. Therefore, silage technology has a relatively large limit on the processing volume.

[0007] In order to improve this defect, there are also technical reports in the field that do not use silage ponds, that is, ground silage (such as the patent document with application number CN201010239372.1), but the silage period is long under normal temperature conditions, and the silage quality is general. Palatability and nutritional content also have a greater impact

[0008] In addition to many problems in the production method of silage straw feed, there are also some unavoidable defects in silage straw feed

It is well known that silage straw feed can maintain vitamins and other nutrients more effectively than hay feed, but it contains a lot of acid, which is especially unfavorable for female animals and may easily lead to abortion of female animals; for male and female animals, the palatability is not good at the beginning of feeding. Good, and easy to loose stools, adding 2% sodium hydroxide can alleviate the diarrhea phenomenon of feeding cattle, but the effect on other livestock feeding is still not ideal
