Abstract

PURPOSE:To make it possible to prevent the putrefaction and deterioration of a raw feed and efficiently store the feed, by cutting off the circulation of air to a layer of the raw feed and inserting disoxidizing materials consisting essentially of iron powder absorbing oxygen into the raw feed layer. CONSTITUTION:An air barrier film 5 is spread on a filled layer of a raw feed 3, e.g. corn, stored in a silo 2, etc., for cutting off the circulation of air to the layer of the raw feed 3. Weights 6 are then placed thereon. Disoxidizing materials 4 consisting essentially of iron powder absorbing oxygen are further inserted into the layer of the raw feed 3. This method is applicable also to an already constructed silo structure and the raw feed 3 can be efficiently stored while preventing the putrefaction and deterioration thereof without installing a new power source.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a raw feed storage method that is effective for livestock farming and efficiently stores succulent feed with relatively high moisture content while avoiding spoilage and deterioration. be.

<Prior art and its problems> Conventionally, succulent feed such as corn, vetch, and sweet potato vines have been cut into pieces and stored in silos. Since the raw feed packed in the feed is made of cowhide, it has a respiration effect, and when carbohydrates are decomposed and oxygen in the silo is consumed and carbon dioxide gas increases, the plants stop respiration.

Next, sickling bacteria begin to act, and lactic acid bacteria brought along with the plant mainly break down sugars and create lactic acid. For this reason, the lactic acid makes it acidic, which inhibits the growth of spoilage bacteria.

However, in actual silos, it is difficult to ideally prevent decomposition and deterioration, and 20 to 30% of the silo, especially the upper part where there is a lot of air left during filling, decomposes and degenerates and is used as feed. Useless parts are usually occurring.

Conventionally, measures to prevent decomposition have included simply placing a cover on the upper layer or placing a weight on it, but both methods were incomplete. In addition, in order to artificially maintain the acidity inside the silo from the beginning of loading, treatment methods using acids such as sulfuric acid, which are chemicals, are used, but handling the acid is dangerous and complicated.

Recent related technologies include JP-A Nos. 54-146746, 55-68252, 55-71444, and 51-
No. 57567, and a wide variety of objects can be stored in silos, including grains, but all of them have the problem of requiring a special silo structure or mechanical power for gas transfer.

<Objective of the Invention> The present invention solves the above-mentioned drawbacks of the prior art, enables efficient storage of cattle feed while avoiding spoilage without providing a new power source, and is applicable to ready-made silo structures. The purpose of this invention is to provide a storage method for cattle feed that can be used to store cattle feed.

<Structure of the Invention> The present invention blocks the flow of air to the cattle feed layer, and
The present invention provides a method for storing cattle feed, which is characterized by inserting a deoxidizing material mainly composed of iron powder that absorbs oxygen into the cattle feed layer.

The present invention will be explained in more detail below.

FIG. 1 shows an example in which the method of the present invention is applied to an existing silo 1, but it is not limited to a silo, but any device that can block air circulation may be used.

In addition, feed includes ryegrass, millet, etc. in addition to the vetch described above. In the silo L, shredded cattle feed 3 is filled into the silo space through a window 2. At this time, especially the deoxidizing material 4 is interspersed in the packed bed of the cattle feed 3. In this case, since air enters from one side of the packed bed, it is preferable to scatter more deoxidizing materials 4 in the upper layer.

After filling the cattle feed 3 and scattering the deoxidizing material 4, an air barrier membrane 5 is installed to prevent air from flowing into the packed bed of cattle feed.
When spreading the material over the packed bed, and more preferably at key points on the outer edge of the packed bed, it is best to place weights 6 on it so that it can follow the sinking of the packed material. Promotes early proliferation and suppresses corrosion deterioration.

After the production of lactic acid is finished, the reacted deoxidizing material can be easily separated when the packed material from the packed bed is used as feed, and only the deoxidizing material is consumed in the once-a-year cycle.

There are various types of deoxidizing materials, both organic and inorganic, but in terms of economy and feed safety, those that are mainly made of iron powder and use salt as an oxidation aid are superior and inexpensive. The deoxidizing material is
When charging into a succulent packed bed, it is packaged in an air-permeable packaging material and is dispersed and charged in large quantities in the upper part of the packed bed where spoilage is relatively likely to occur. Note that the amount of the deoxidizing material charged is determined according to the amount of residual air that can be calculated from the porosity of the shredded cattle feed filling layer in the silo.

The membrane that substantially blocks air flow to the packed bed may be a combination of rigid and flexible materials, or only flexible materials, and the outer edge in contact with the wall of a structure such as a silo may be made of sand, etc. It is preferable to provide a weight with a bag filled with granules or a fluid such as water. A synthetic resin sheet such as vinyl or polypropylene can be used as the membrane that blocks the flow of air or the like.

Example: Cut the corn at the yellow ripening stage, and when filling it into the silo, apply a deoxidizing material mainly composed of iron powder to 1.2 tons of the filling material.
0 kg was charged, and the upper layer was covered with an agricultural vinyl membrane with a thickness of 0.2 mm to block air circulation. The results of investigating the silage fermentation quality after three months are shown below.

Deoxidizing materials are 50% iron powder, 4.5% salt, 6% activated carbon, 2% sea sand.

．． 0 0 <Effects of the Invention> In the present invention, in order to prevent stored materials from decomposing and deteriorating, deoxidizing material can be charged into the silo without newly installing a silo structure, a power machine and a power source for the same. Then, by cutting off the flow of air to the storage container by means such as providing a cover on the top of the layer, lactic acid fermentation can be promoted, the growth of rotten parts and mold can be eliminated, and quantitative loss of stored materials can be prevented. Furthermore, it does not cause a decrease in the nutritional value of the feed, and is extremely effective due to its simple method.

Furthermore, when feeding from the silo is started, secondary fermentation such as putrefaction occurs because the storage layer is exposed to air. Corruption can be significantly reduced by cutting off supply.
