Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing feed using rice husk and rice bran.

Rice has played an important role as a staple food in Japan since ancient times, and although there was a time when rice husks and rice bran were used as fuel, they are no longer used as fuel today, and after the war they were used as cushioning materials. Although it was sometimes used, it is hardly used today.

However, the reality is that many parties involved are at an impasse when it comes to disposing of the rice husks resulting from overproduction of rice, and many are at a loss as to where to dispose of the rice husks without a concrete solution.

The present inventor has been conducting research and development on fermentation methods using microorganisms for many years, and now we have developed a method to utilize rice husks and rice bran, which are difficult to treat as described above, as regenerative resources. and Aspergillus oryzae fujita (Aspergillus oryzae fujita).
This product was developed for the purpose of providing a method for producing a feed in which the feed is inoculated with A. yzae Fugita) (National Institute of Microbial Technology, Agency of Industrial Science and Technology, Bacteria Deposit No. 2575) and fermented and aged.

Here, Aspergillus oryzae Fugit
To describe the characteristics of a), (a) the tip of the conidiophore becomes enlarged and becomes an apical capsule, and a large number of sycamores are attached, and conidia are formed in a chain form from the tip, and (b) angiosperm and apical capsule. No ascospores are formed, (-the apical sac is not rod-shaped, (d) the colony is green or greenish during growth, (the walls of the conidiophore are rough or spiny, ) Colonies are green or green or yellow-green.

To describe an example of the method for producing feed according to the present invention, 200 kg of rice bran is mixed with 1000 kg of rice husk.

Then, 1000 L of animal blood is added, and the reason for adding the rice bran is to facilitate blood adsorption.

After mixing and stirring, Alpergillus Lt.
oryzae fugita, National Institute of Microbial Technology, Agency of Industrial Science and Technology (Bacteria Deposit Number 2575) was inoculated and the fermented mixture was heated to 30°C and fermented for 12 hours. It became ℃.

At this point, the first round of cutting was carried out, and after 15 hours had elapsed since the cut-off was accumulated, the fermented product had a quality of 45
It has become ℃.

So, at this point, I made my second cutback.

When this second round of cutting was performed, the moisture content of the fermented product was 5.
Since the water content decreased by ~7 parts, the water content was adjusted to 55 parts.

If this is left for about 20 hours, the humidity of the fermented product will repeatedly fluctuate between 50°C and 55°C, and the pH will also reach 6.
It repeated up and down from 3rd to 6th place, then stopped.

At this point when it came to rest, it was further cut back and further aged for about 20 hours.

This completes the feed, but it may be dried and ground to suit the taste of the animal.

As a result of analyzing the feed obtained by this invention, the water content (
Normal pressure drying method) 10.1%, crude protein (coefficient 6.2 5)
22.4%, crude fat (Soxhlet extraction method) 4.9%,
Crude fiber: 6.6%, Crude ash: 9.1%, Soluble nitrogen-free matter: 39%
．． It was found that the content was 9%.

The crude protein coefficient 6.25 is a coefficient to be multiplied to convert the N content obtained by analyzing feed into protein, and is the value when the N content of protein is 16% (10
0/16 = 6.2 5 ).

The results of a test in which this feed was fed to egg-laying hens are as follows.

(1) Test period June 10, 1970 to August 4, 1978 (8 weeks) (2) Tested 12,000 hens (60 days old) (3) Test item a) Egg laying Rate a) Incidence of soft broken eggs and scratched eggs c) Eggshell quality and unit rate) Total cholesterol content in the egg yolk Note that (b) scratched eggs refer to eggs with scratches on the inside of the eggshell, and are usually not visible to the naked eye. cannot be detected, but
They can be identified when exposed to light from the outside (usually sorted using an egg wash and sorter).

Academically, it is considered an oddly shaped egg.

(4) Method Shaver type layer hens (60 weeks old) were divided into two groups of 6,000 birds each, and 8
A weekly salary test was conducted.

(5) Test category The feed used in the control group is a commercially available complete compound feed that complies with the Ministry of Agriculture, Forestry and Forestry's official standards for raising adult chickens.

As a result, we were able to obtain results as shown in the following tables.
