Description

[Detailed description of the invention]

The present invention relates to obtaining eggs of superior quality. In recent years, raising chickens in large numbers using cages has been widely used in egg-laying hens, but while maintaining the number of chickens raised per unit area at a high level through cage rearing, it is possible to further improve the egg production rate and the amount of eggs collected per chicken. At the same time, it is desired to improve the quality of eggs, strengthen the eggshells, reduce the rate of egg breakage, and efficiently produce large quantities of high-quality eggs. In addition, although drugs such as sulfur drugs and antibiotics have traditionally been used frequently to prevent the outbreak of diseases, there are concerns that they may cause resistant bacteria and transfer to the human body, so poultry farming methods that do not use these drugs have been proposed. desirable. The present inventors have discovered that by adding fermentation microorganisms to feed and raising chickens using this feed, the health of the chickens can be maintained and improved, and more eggs of excellent quality can be obtained from chickens with physical strength. The present invention was completed based on this discovery. The fermentation microorganisms mentioned above can be non-contaminating, non-irritating, non-toxic, and include cellulose-degrading bacteria, hemicellulose-degrading bacteria, proteolytic bacteria,
It contains lipolytic bacteria, lignin-degrading bacteria, pectin-degrading bacteria, and carbohydrate-degrading bacteria, and at least one of these cellulose-degrading bacteria, proteolytic bacteria, and carbohydrate-degrading bacteria is Bacillus subtilis. It contains bacteria. For example, something like this:
PETE” (Product name: 4-12 Kashima, Yodogawa-ku, Osaka)
31 (manufactured by Microbial and Environmental Technology Research Institute), and among them, for example, "ETTEL PETE 1160" has all bacteria derived from plants, and as mentioned above, it is non-contaminating, non-irritating, and harmless. The degrading bacteria mentioned above include the following. Γ cellulose degrading bacterium Bacillus megacerium
megatherium Bacillus subtilis Ruminococcus Γ hemicellulose and lignin degrading bacteria Bacillus macerans Clostridium dissolvens Γ protein degrading bacteria Aspergillus
niger) Aspergillus flavus (Aspergillus
flavus) Bacillus subtilis Gamma lipolytic bacterium Neurospora cytophylla
sitophila) Γ pectin-degrading bacterium Penicillium glocum (Penicillium glocum)
glaucum) Γcarbohydrate-degrading bacterium Bacillus mezenthroid (Bacillus mezenthroid)
mesenteroides) Bacillus subtilis This fermentation microorganism may be used as is, but
Usually, rice bran, bran, etc. are used for propagation, and these materials are mixed into feed. For example, add about 30 kg of hot water to 100 kg of rice bran and mix until the moisture content is about 31% and the temperature is around 40°C.
Add about 100g to 1kg of ``PETE'', mix well, cover with a cloth or sheet to keep it warm, and leave it overnight to allow bacterial cells to proliferate. Approximately 5 to 35 kg of such material is added to commercially available mixed feed/ton, mixed well, and fed to chickens in a conventional manner. In some cases, an inorganic substance such as Soyoseki powder may be added in approximately the same amount as above. When chickens are raised according to the present invention, they eat food quickly, their physical strength increases, their survival rate increases, and the amount of eggs they collect increases, making egg collection more efficient. Chickens also tend to peck at red-colored objects with their beaks, and when chickens are in a hysterical state, they often peck the butts of other chickens in the same cage, pulling out their intestines and killing them. The phenomenon of this phenomenon was no longer visible.
In addition, the number of eggs increased, the quality of the eggs improved, and the rate of egg failure decreased. In addition, in multi-cage chicken farming, the water content in the feces increases, making it difficult to dispose of the feces, causing the occurrence of mosquitoes and flies, and causing foul odors. The water content in the poultry feces has also decreased, making it dry and normal, and the occurrence of mosquitoes and flies in the poultry house, as well as bad odors, have also decreased. In this way, the chickens have gained strength and the environment inside the chicken house has improved, so the average number of chickens per 10,000 chickens per year is about
We were able to continue raising the animals without using antibiotics or other drugs, which cost around 1 million to 1.6 million yen. An example of the rearing test will be described below. Test [1] Test of egg production rate, etc. (1) Test conditions Γ Test chicken Breed: Dekalb Chicks born on March 10, 1982
Forced molting started on August 16, 2017 Number of Γ chickens: 446 Γ breeding conditions Width 22.5 cm, depth 40 cm, height 45
Place two birds in a cm cage and arrange the cage in two stages. Γ Examination period: October 11, 1982 - January 1982
Month 9th Γ Invention area About 30 liters of hot water for 100 kg of rice bran
Add ETTEL・
Add 300g of PETE1160, mix and leave it for a day and night.
Showa Sangyo Co., Ltd.'s compound feed
Mix in 3S Z1t,
The animals were fed and reared in a conventional manner from the 130th day of age. Γ Control group Only the above 3S Z was fed, and the others were raised in the same manner as the main study group. (2) Test results The chicken survival rate, egg production rate, and egg yield per chicken are shown in the following table.

[Table] (3) Discussion The survival rate, egg production rate, and egg yield per chicken were all improved in the invention plot compared to the control plot. In particular, the amount of eggs collected per bird, which indicates egg-laying efficiency, increased by 2 to 11.5 g compared to the control plot. Test [2] Egg analysis test (1) Test conditions Eggs laid on December 7, 1980 in Test [1] were used. (2) Test results

[Table] (3) Discussion It can be seen that the present invention plot has a higher content of minerals such as iron, calcium, and magnesium, and vitamins than the control plot. Test [3] Egg quality test (1) Test conditions Γ Test chicken Breed: Dekalb Age: 250 days Γ Test eggs Eggs laid on February 16, 1980 were used, and the average value of 10 eggs was taken. . Γ Breeding conditions The invention plot and control plot are the same as the above test [1] (2) Test results

[Table] (3) Discussion Compared to the control plot, the plots of the present invention showed superior results in egg weight, albumen height, how unit, color (yolk), eggshell thickness, and eggshell strength. This increase in egg weight directly increases economic value, and eggs with good albumen height, high unit weight, and color can command high market prices as high-quality eggs. It also improves the shelf life of eggs as a whole. Furthermore, good eggshell thickness and eggshell hardness lead to a reduction in egg rupture rate, which in the area of the present invention is approximately 3.5% (the national average is said to be approximately 7%).
